I'm currently pricing a House Rewire and the Client wants TV/FM & SAT in each room. Can someone please give me some advice as to how to go about this please? I've only ever wired standard tv aerials into the loft before so it's all new to me.
The easiest way is to use a diplexing distribution amplifier, such as a Global T8 Loftbox. These allow the diplexing of multiple signals down a single cable then splitting it out using a diplex / triplex faceplate into TV, Satellite and DAB /FM.
The loftbox will take inputs from a TV Aerial a FM / DAB Aerial and a satellite dish and combine them into one feed. This cable goes from the Loftbox to the room and splits into its components using a special faceplate.
The importnat thing to remember if you want to go down this route is to use good quality cable such as as WF100 / CT100 or WF125 or CT125. Do not be tempted to save money and use cheaper RG59 or RG6
The best thing is to seek advice from someone who does and is paid to do so in the aerial trade.
Also the client needs to specify exactly what is required. Your spec is too vague at the moment.
Antennas (dishes and aerials) will be required too and that needs some specialist skills to install and get right.
The way described above is now old-fashioned and won't work with $ky Q installations... and the latest freesat boxes use the same 'wideband' lnbs that cannot be di/tri/quadra-plexed with filtered plates.
That may or may not matter on this job, but.
What about DAB radio? CCTV cameras? PVR viewing in other rooms?
iPTV is becoming more important so ethernet wiring would be a sensible install.
Yeah sorry should have mentioned that $kyQ will not work with ANY form of distribution amp or Multiswitch as there has to be a continuous feed from the LNB to the $kyQ box. Even an in-line connector such as barrel will cause it to fail the install. But a loftbox will take a feed from an older Minidish and LNB and quite happily feed most freesat enabled TVs.
If its a $skyQ install we tend to provide a pair of WF100s to the dish location with 1 -2 m hanging outside and take them back to the location of the main box(s) and again bring them through a brush plate with a metre or two un-terminated and let the $ky engineers do their own termination and hook up. They actually quite like this as it saves them slinging the sh*tty shotgun RG59 that they all seem to use today.
My experience with aerial installers is a bit hit and miss with diplexed installations I would tend to let them put the aerials up and provide drop feeds and go from there.
CCTV we tend to use Digital RF Modulators for distribution via RF as you can push a 1080p signal to most TVs.
I'm an Electrician obviously, doing the rewire and I usually just wire a co ax into the loft and then ask the Client to get an aerial expert to come and install the aerial and make the connections in the loft when I'm done.
I'm planning to do the same on this job but I'm not sure where to start with the wiring. I think I need to get some more information off the client.
Just out of interest, when I've been in new build houses, they all seem to have the plates with tv/fm/sat. Now, I think that's what he's trying to achieve. If so, is it just a case of running a ct100 cable to a central point from each plate? And if he needs it to work with sky q, then how would that be wired?
‘Obviously’ - I never assume, we come across all sorts of folks tasked with areas of a contract.
Client - you must have that conversation, and as others have suggested it can be a fairly complex conversation when you have a modern family with multiple requirements.
New build - I would not use the usually outdated, low cost, badly thought out wiring you see in your average New Build as your starting point for a multi-occupant, multi-room, home entertainment system if you are offering a wiring plan specific to your customers needs.
In wall Conduit - may be your smartest route and give the client/entertainment system installer a bit of a head start.
