TV points wiring

[driverman]

Touched on this before in another thread but unable to find. I've started to first fix a TV system. At the moment I've done it as old standard ie from aerial to amp in loft then down to various TV points. TV point in lounge will be near the BT / Sky box etc. Would it be better to run a coax down to Bt /sky box from aerial first, then back up to amp in loft and then from amp to each and every TV point. If done that way, would the smart TV's in various rooms all be able to use the Bt / sky facilities offered. Thanks

Yes run aerial down to main point and a return to the distribution unit Sky will be available via RF2 but recent BT boxs will require a modulator to feed other TV's via distribution unit.

Do you have a TV aerial "buddy"? If so talk to him about the multi channel splitter amps available and make sure you have a socket in the loft ready!

Yes provision for a twin socket to be sited in the loft (on it's own circuit) in readiness for TV amp. Re splitter, thanks, I will do. 7 x TV points required, all of which will be wall mounted TV's.
There is a possibility of an 8th TV point required in a studio flat above a detached garage. TV coax cable via u/g in ducting? think I'd had better measure overall distance of that particular one.
So to confirm lounge situation. aerial >>>> to BT/SKY >>> back up amp in loft >>>>then back down to TV point in lounge.
When connecting the 2 x coax cables by the BT /SkY boxes...possibly one standard plate, whereby both coax cables are connected separately? in the back
PS by standard I mean 1 x plate with 2 x separate outlets.

I always install loft boxes which distribute the two sat feeds, freeview, fm, and return to loft box.

You need 3 coax cables from your loftbox to lounge tv (all in one deep 2g box) then one coax from loftbox to each tv.
You the take your two sat feeds from your dish and aerial feed to the loftbox and do all the connections there.

Many thanks for your reply. i've used RG6 cable solid core....75ohms resistance. Is that acceptable for modern day requirements? What do you use?

I've always used CT100 now called WF100 I believe. I think it's about £70 for a 250m drum. RG6 should be alright although it is a lower grade cable, RG6 uses an aluminium screen and copper braiding whereas WF100 uses copper screen with copper braiding. Just take care when running RG6 as it's very flexible and susceptible to kinking and snagging. Shouldn't be a noticeable difference between the two once installed though buddy.

£50.99 + £5.99 P&P on eBay for 250m drum.

Thanks, already installed RG6..........but will remember your cable if ever i do another TV install. Taking it stage further, especially for the main wall mounted TV in lounge which will sited near /above BT / SKY boxes. I intend to install at least 2 x HDMI leads flush behind dot -dab plaster board. Is there a better way of terminating the cables at either end/ I'm a bit concerned if left hanging out from plasterboard, the plasterer float may cut / damage them. I'm possibly thinking of installing flush conduit /trunking behind dot dab and instal afterwards. No doubt many on here who this type of work have other ideas. Would it be a good idea to instal cat5 also? Anything else that I've forgotten for the modern home?

Hard wired phone points
Hard wired network points
Hard wired CT 100 cable x 2

That neatly fills a 2G 47mm deep box - so that's most things covered.

As for cables hanging out of walls - use the grid plates with the "brushes" - looks neater and protects the cable.

By using deep box, you mean first fix HDMI and coil them up inside the box out of the way of plasterer etc?

No, just remember to use a deep back box where you may be terminating up to 4 different "devices"

Be careful bending hdmi cables inside boxes, we used to leave them hanging out of the wall but covering the first 6inches or so in flexi conduit to protect from trowel or coiling them up inside a plastic bag.

Trunking or conduit is a good idea as it allows for future cables to be pulled in, 2x Cat5/6 is always a good back-up

On my own home, i tried adding HDMI cables at a later date by going up behind the dot-dab.I did manage to get a draw wire behind the plasterboard but the gap was not sufficient to get the terminal heads of the HDMI cables up. So in order to get the HDMI cables to work , I went against all my principles and drilled straight through cavity wall to outside then back in behind TV itself for a temp measure. Year later I thought, hang on, they are not LV cables, so redid them up the actual cavity wall. Out of site now..........Hate seeing any type of electrical cable on show!

Are you able to terminate HDMI cables within an accessory? I've taken your advice from a bit back re hard wire data / phones etc but my customer (family member) doesn't seem to want them. Answer I get is wireless this that and the other. Ah well, I can only advise! . As it is a new build, it's not that difficult to install as opposed to an occupied dwelling.
