HDMI to Cat6 Tx

How to send a Foxtel box into another room via HDMI, TV antenna or Data cabling part 2

Disadvantages are;

  • There is no built in option to change Foxtel channels from the second room without purchasing addition equipment.
  • HDMI modulator will cost more then an AV digital modulator, AV digital modulator use the yellow/red/white leads, there is a very noticeable picture quality difference between the two standard definition and high definition digital modulates.

Addition equipment to think about; if you would like the ability to change the Foxtel channel from the second, third, fourth ect room, there are devices available to connect to the TV antenna cabling to transmit the remote control back to the Foxtel box.

HDMI over cat6 data cable for multiple Foxtel boxes and longer runs

This option can solve all of the problems listed above, Single HDMI extension kitthere are also a few different options we have available by converting the HDMI into data cable.

The first advantage is, if you have a need to only transmit the Foxtel to one room, we can mix the HDMI signal from the Foxtel box on to a single data cable and then run the data cable up to 70 meters to any TV your home or outside into the man cave. This option is ideal for long runs and only to a single TV.

The second option is, locating all your Foxtel boxes in a single room/cupboard/comms cabinet so they are all out of sight and then mixing them all into a matrix bHDMI to Cat6 matixox. This type of system is too complex to explain in this blog but it can be expanded for example up to 8 inputs and 8 outputs, all 8 TVs have the ability to see all 8 inputs/devices connected, so in simple terms you could input up to 8 Foxtel boxes and HDMI to Cat6 matrix plantransmit to 8 TVs OR input 4 Foxtel, 2 Blu-ray players and a PS4 (as the PS4 uses Bluetooth for the controllers, you would have to be in the next room for this to work) and leave the last one spare for future use. This option gives you the ability to also change channels as well from all the rooms.


There is only one disadvantage, if you have an old TV connected and it is only a standard definition, the matrix will down scale the image to suit the oldest TV (to eliminate and conflicts in the picture), this means if you have a new HD TV or UHD TV, you will see the image in standard definition, this is only because if the old TV, once all the old TVs are updated, only then will the matrix transmit in full HD.


Depending on your requirements will depend on the equipment need, there is no reason why you can not do any of this yourself, but you need to understand that the more complex the system you go the more critical it is to correctly install the equipment, if not done correctly damage can occur to the equipment or the equipment connected. we always recommend something like this be install be a repeatable home theatre installation company.

Send a Foxtel box to another room via HDMI, TV antenna or Data cabling part 1

Setting up Foxtel in another room is all legal so you don’t have to worry, setting up a second, third or more room without a second set top box has its advantages and disadvantages, but it is a great way for you to save money in the long term with a little bit of outlay upfront, there are a few different ways to achieve and this and it will all depend on your overall requirements. From running a single HDMI cable to another TV in another room, to mixing it in with the TV antenna system to using a 3rd party device specially designed for long cable runs and distribution.

HDMI cabling

The simplest and cheapest way is to run a HDMI lead from the Foxtel box to the second TV, but there are limits involved and some extra equipment is needed as well. If cheap and easy is all you want with high quality audio and video, then this option is all you will need, though on the back of the Foxtel box there is only one HDMI output, so how do we split the signal? Easy, we use a HDMI splitter. So to sum up this process we take a HDMI cable out of the Foxtel box and into a HDMI splitter, then one lead will go back into the original TV or amplifier and the second output lead will go into the new TV in the other room.

The advantages are;4 way HDMI splitter

  • High quality video and audio to both TVs.
  • Cheapest solution with without compromising the video and audio.

The disadvantages are;

  • All TVs will see the same channel.
  • HDMI has a limit of 20 meters, the longer the HDMI cable is, the more the will signal degraded, so the second, third or fourth TV would need to be in either in the next room or so for this fix to work.
  • There is no built in option to change Foxtel channels from the second room without addition equipment.

Addition equipment to think about; if you would like the ability to change the Foxtel channel from the second room, there are devices available to transmit the remote control back to the Foxtel box.

Mixing it with the TV antenna

Mixing the Foxtel in with the TV antenna eliminates some of the problems from the first solution. Once the HDMI signal form the Foxtel box (or RCA signal, the yellow/red/white lead) is mixed in with the TV antenna through a digital modulator, only then will every TV HD digital modulatorantenna point be able watch Foxtel on a digital channel, and because we used HDMI to mix into the TV antenna, we will see the Foxtel on all the other TVs in a high definition channel (unless we used the yellow/red/white lead, we will then only see it in standard definition).

Advantages are;

  • We are not limited to distance as much.
  • We can send the signal to all the TVs in the house.

TV antennas


There are many types of TV antennas on the market. But choosing the right one and installing the antenna yourself can be difficult. Some do look similar but perform differently. we’ll go through the main ones so you know which TV antenna is the best one for you with-in the Newcastle, Lake Macquarie and the Hunter region, as different parts of Australia will need different TV antennas.


To start off with, the most common type of antenna is the Yagi TV antenna. Back in the days of analogue TV reception, this kind of TV antenna was ideally used for line of site to the TV tower (and still can be used with digital). A Yagi antenna can come in different lengths. This will plays two roles, first off it is to focus the TV reception, and then second, the longer the antenna is, the more focused it is. As a result, the antenna will pick up more reception (gain). This type of antenna was also the cheap when bought in its shortest form because it had low gain.

Unfortunately, analogue TV reception has it’s bad points, which one was, it can produce ghosting images on the TV. This is due to a reflected signal from something like a mountain or building. The TV antenna would pick up the reception from another angle and then introduce it into the antenna. So both signals, the reflected and original signals are both displayed on the screen at the same time. Depending on the distance and the strength of the reflected signal (off the building or mountain), this would tell us how bad the reflected signal would be (the ghosting image). One way to combat this was to move the antenna in a different direction. Turning the antenna as much as possible to 90 degrees of the ghosting signal or better yet install a high gain (longer antenna) TV antenna to focus the main reception more is better again. Yagi TV antennas are still used and are still an excellent solution to a problem that needs to be fixed, but only if you line of site to the tower.

A standard gain Yagi TV antenna on the right. This antenna is short in length, as you can see on the left, the radial pattern diagram of the antenna starts to really loose reception at 30 degrees. At 90 degrees it will not pick anything up at all.


High gain yagi TV antennaA high gain Yagi TV High gain yagi TV antenna radial patternantenna pictured on the right. Notice the length of this antenna is longer than the antenna above. The radial pattern on the left for this antenna show that the reception really drops off at 15 degrees. This antenna is more directional then a standard gain antenna.



There is another type of TV antenna that is used and mostly seen these days in and around the Newcastle area. The main reason it is common is that it is an excellent all round antenna. The phased array TV antenna is flatter and again comes in both standard gain and high gain. Back in the analogue days, this type of antenna was used to fight scatted TV signals. So for example, if your home is surrounded by trees in the bush, the idea of this type of antenna is that the large flat area would be big enough to pick up scatted reception. If a tree was in front of the TV antenna and was blowing in the wind, each time the tree moved, there was still some kind of a path through the trees for the antenna to pick up the reception.Phased array TV antenna radial patternPhased array TV antennaPhased array TV antenna radial patternPhased array TV antenna
On the left is a Phased Array TV antenna, notice that it is a flat TV antenna. This antenna has a larger surface area to pick up the reception from scattered signals. The radial pattern on the right shows that this antenna is not as directional as the Yagi TV antennas. The reception starts to drop off at 30 degrees and even more so at 45 degrees.


With digital TV, we won’t see this issue as much as we did with analogue TV. The signal is either there or not, but the signal can also have “digital errors” within the signal. Without the proper equipment to find the problem, knowing what the problem is will be a lot harder and you can be running around in circles wondering why the TV keeps freezing or saying No Signal (square boxes and the picture freezing). There can be many reasons for this and it’s always going to come down to the location of course. If you are down in a gully or surrounded by a lot of trees, this will be worse than being high up on a hill of course. Also, if your antenna equipment is full of rust (not necessarily falling apart) or your antenna equipment is ancient, this can also be a major problem as those parts may need upgrading, not to mention the type of TV antenna you’re now using as some antenna just are not up to standard. Other major problems can also be poor workmanship from the last antenna installer, so keep an eye out for that as well.

As a conclusion

Have a go yourself, but if it doesn’t work and you end up giving up, you’ll then have to call us in to fix your TV antenna installation problem. As a result, you could be paying a little bit more than if you would have called us in originally, trying to achieve something yourself is great but you could be just giving yourself more headaches. Please note, a TV antenna booster will not always work, the reason is if you start with bad reception, you will only boost bad reception.

What Can Be Mixed Into A TV Antenna System

TV Antenna Distribution

Antenna Distribution layout

A TV antenna system can be a simple single TV outlet system, all the way up to a complex commercial system with hundreds of outlet. Mixing the satellite dish in and FM radio with other in-house services is possible too. It is possible for other devices to be distributed through your TV antenna system. Things like a DVD player, Apple TV or even security cameras. Your current infrastructure can be used without having to install extra cables to other rooms. But this will depend on if you need things like remote control signals to go back to the source device.

Installing an external FM radio antenna is a superb idea if you enjoy listing to FM. Connecting an external FM radio antenna is best if your in an area where you have poor radio reception. Then mixing it into your TV antenna system, along with other devices can be done. At every point in the house, you’ll be able to plug in your FM radio and listen to FM stations much clearer than before. There is a noticeable difference if you have a two-story building, and your radio is downstairs.

Do you have a Blu-ray player or Foxtel that you would like to distribute throughout the house or business as well? With our wealth of knowledge, this is possible too. At the other end, you can potentially receive HD quality picture as well.


As a conclusion, if any antenna installer says it’s not possible, we would recommend you thank them for their services. Give us a call ASAP so we can sort you out and have things running the way you need it to be.

Freeview Plus – What is it?


So we’re all enjoying Freeview with a new digital TV antenna, and all the benefits it has to offer like a 7 day program guide, setting up timers and multitude of channels (unfortunately some channels we’ll never watch), and just as we’ve mastered this, a new technology is just around the corner, in May 2014 it is set to start, Freeview Plus , oh on not something else I hear you say, so what is it?

Freeview Plus is a hybrid technology which mean it uses a mix if the internet and free-to-air digital TV, technically it uses HbbTV (Hyper broadcast broadband TV) technology. Freeview Plus has some benefits over the current Freeview and of the main benefit at the moment is the ability to catch up on TV show that was missed, as well as all the other features like setup “favorites” and an extended EPG (electronic program guide).

Current “catch up” shows are limited but can be seen here from Freeview here.


For those that already have TV’s connected to the internet, there some channels available to us like “iview”, “SBS on demand” and “Plus 7”, this is all internet TV through a smart TV or a “smart box” connected to a TV, another form of IPTV (internet protocol TV) we featured some time ago was in our blog about NAS systems and streaming DVD and Blu-ray movie that are stored on a hard drive in your home to all the TV’s in the house that are connected to internet, no need for a DVD or Blu-ray player any more.

There are other forms of internet TV that is already here and are all in some kind of set top box form, some we would of heard of and some not, and some of the suppliers are Telstra’s T-box, Apple TV, Google TV and iinet’s Fetch TV, so internet TV has been around for a while but Freeview Plus is a new technology and it will be interesting to see how it will take off and be accepted by everybody.

Will this mean another box, more remote controls? We hate to say but most likely yes, as this is a new technology, some current model smart TV’s may be able to download and use Freeview Plus but the most of us will need a new/another set top box to use Freeview Plus.


As technology evolves, gone are the days where only an antenna cable is run to the TV, now with the invent of the internet, the TV’s having the ability to connect to the internet and a NAS, and now Freeview Plus, running a data cable to each TV has become the norm not an option, some TV’s do come with wireless built in and that’s great where a data cable cannot be run to, but to ensure the TV receives to full bandwidth of the network a data cable should be run, when there are many devices connected via wireless like laptops, Ipads, Iphones ect ect, this can create congestion in the network and slow the wireless down, so it’s always best to run a dedicated cable to each device if possible and if building a new house, or shop that will use TV’s as a display, this now is a requirement as to stay up to date with technology.

Custom Audio Visual Solutions can install a new digital antenna and data outlet for Freeview Plus. We service Newcastle, Lake Macquarie, Hunter and the Central Coast.

Domestic FM Radio & TV Antenna systems


TV antenna systems are different for both commercial and domestic situations, so in this blog, we’ll be only looking into the domestic system. Although a lot of this information will also apply to a commercial TV antenna systems for clubs, pubs, apartments and units, we will talk about a small system in a house.


TV AntennasIn the last few year with the transition from the old analogue system to the new digital system, there has been a big fuss about “digital antennas” and how important it is that everybody has to change their existing TV antennas over to a new digital TV antenna to receive digital signals. Whenever the subject comes up, all that is heard is that it is necessary to change the antenna over to a new “digital” antenna, but is that really the case. There are only a few reasons to change your TV antenna over, and the main reason would be if the picture on the TV is breaking up (pixelating or freezing). Of course, if your TV antenna is about to fall apart then that’s another adequate reason, but who can honestly say they look at their antenna? We’ll get to some more reasons a little later on.


Has anyone ever looked around at different antennas installed? Have you ever noticed that each house has a different antenna, so why do they all look different? Nearly every house has something different on its roof. It all goes back to the analogue days, where we had a mix of TV stations on VHF as well as UHF, and your location in relation to the TV tower dictated how much TV reception was received so hence different TV antennas were used. So as a legacy of the good old days, a lot of houses still have the original antenna on the roof, not to mention the very tall masts to pick up TV stations from Sydney before all the channels were available in Newcastle. Today with only digital TV available, none of this is necessary anymore, but do you need to change your antenna over to a new digital antenna?

There are two different thought reasonings to this question; the first being is if the TV has a picture, why should I change the antenna over? You would think it’s not required and 99% of the time you would be right. This reasoning is valid but floored at the same time, for example, we have seen VHF antennas still picking up digital UHF reception. Every TV antenna will pick something up, but it all comes down to the amount of TV reception, the quality of the TV reception and the “digital errors” in the reception that the antenna is picking up. Also, all TVs have a threshold where the TV needs a minimum amount of reception to produce a picture on the screen, if it falls below the threshold or there are too many “digital errors”, that is when the TV will start to pixelate or even start saying “no signal”. As a result, nobody will know how much reception any antenna is picking up until a qualified antenna technician connects a signal meter to analyses the signal. But as a given rule – if there is a VHF antenna on the roof and regardless of the reception it is picking up, that antenna will need to come off, it’s not compatible with the new digital signals, and it’s not required for the Newcastle and Hunter areas.


Without getting too technical and from a technicians point of view, every old analogue TV antenna will need to come off and be replaced with a single UHF TV antenna for many reasons. The main reason is compatibility with the digital TV signal. Radio Frequency signals can do funny things including interfering with each other so to eliminate any external interference in any signals; only one antenna should be on the roof to minimise this effect. If another antenna is still connected it can still pick up other signal and it does not have to be RF signals to create problems, other problems can come from things like rust on any of the connections and even a connection done poorly will create problems too. Trees, hills and other building can be a problem too, this can be a matter of just relocating your antenna to a different part of the roof, or possibly having to raise the antenna higher on a mast to get over the problem, or even just point the antenna to a different tower. One thing that is easily overlooked is the coaxial cable and the splitter. If the cable is over 15 years old, there is no doubt that it will need to be replaced, but also the coaxial cable that is attached to the antenna will need to be replaced much earlier as the sun plays a significant effect on its effectiveness over time. All the coaxial cable we use are all UV treated, but even this will only extend the life for a period of time, if any installer tells you that their cable will last forever, thank them for their service and kindly ask them to leave, no cable will last forever when exposed to the sun.


Other problems can come from things that are out of your control, which is the transmitter tower. In the middle of 2013, we come to a home in the Charlestown area, previous to us arriving they had another antenna company there that could not find the problem. The antenna was pointing directly to the tower, and we could see the tower directly, the TV was still pixelating, the installation looked good except there was a lot of digital errors coming up. After talking to the television station’s technical engineers, we found out the errors on our meter was coming from the transmitting tower. After the transmitter was replaced the customer was receiving the channel correctly as if there were no problem at all, we also found out that we were the only antenna company in Newcastle to have called the station to see if there are any problems.


For views that cannot pick up TV reception with a TV antenna, we have a solution for you. We can install a satellite dish to pick up TV station, (like Foxtel) but this service is only available to views that are outside the digital broadcast area (there are no monthly fees like Foxtel).


As a conclusion, you can see that TV antenna problems can develop from anywhere at any time, and multiple problems occurring at any one time is very common as well. Because the industry is not very well regulated, there are a lot of companies that are running around that are ill equipped to handle many of the digital TV antenna problems we encounter that we have listed here. So, as a result, we’ve seen many installations completed poorly. So if you want quality service, and the job is done right the first time, we are the only company you will need to call.
