Wall mounted box for sat

pa990

i ordered a Sat Wall Mounting Box

http://www.hm-sat-shop.de/montage-zubehoer-stecker-und-dosen/antennensteckdose-twin.html

thinking that i could run 4 cables into it , but i only wanted to run 3 (2xsat 1xterrestrial)

But when i opened it up, there are only two holes to insert cables.. i really dont understand how it is suppose to be wired?

has anyone any idea how this is suppose to work ???

Thats a diplexor twin feed box typically used with multiswitches.

They feed in 2 separate feeds, each carrying satellite and an optional diplexed terrestrial feed on both sides.

The feeds are split out on both sides into the satellite and terrestrial. The gender differences are supposed to be RF out ("male" solid centre pin) and a return channel ("female" hollow centre pin). Sometimes it's claimed that these are separated TV/Radio ports. But I've been told otherwise.. that its used to route CCTV through multiswitches. I've found in practice that both work fine for terrestrial TV reception.

To make your 2 sat, 1 ter work.. I >>think<< you only need another diplexor upstream that will combine one of your sat and terrestrial feeds together.. then that single cable should be fed to the side that has the male RF.. solid centre pin.

Something like this:

... trouble is I've never used a combination of these before. In my case, I fed the satellite feeds into a multiswitch along with a terrestrial feed.. then ran cables from the switch to various rooms and these sockets then did the rest.

So I'm not positive that the two are compatible.. hopefully one of the gurus can confirm.

well, i will have 3 cables coming down from the multiswitch, i was gonna use two of them for sat, and one for terrestrial.


(i'm still re-reading your post, it might take a few goes for all of the info to sink in)

Are you using a multiswitch?

if so, then run two cables from the multiswitch to the socket.. as long as your sat and terrestrial feeds are connected to the multiswitch, the socket with do the rest.

i have two cables running to most rooms in the house, (all coming thru a multiswitch) but i have 3 cables coming to the main TV room.

My original ideal was to have 2 Cables for sat and 1 for terrestrial in the TV room

and in everyother room there would be 1 for sat and for terr.

What i will do now is just leave the 3rd cable behind the socket, and use it as a back up or maybe for mmds, or i could use it to send a signal upstairs.

I'll buy a few more of these boxes, now that i am sure that they will do what i want them to do.


Thanks for the help cormaci.


Just to confirm.. I will be running 4 feeds from a Quatro, and 1 feed from a roof top aerial into a multiswitch, this will go directly to each room, I then Put 2 cables into this Box, .. is that right ? or do i need any other equipment?

OK.. here's an update,

The wall box that i have doesn't fit well on the wall.

What are my options now ?

I dont fully understand exactly how the multiswitch works.

- Will i be able to receive a Terrestrial signal from the multiswitch
outputs with out any other equipment ??

- If not, what piece of equipment do i need?

As long as you are mixing satellite and terrestrial inputs, you will need to have a diplexor fitted at the other end. Remove the terrestrial aerial feed on the multiswitch and you can fit standard satellite sockets (the ones with the female F-tpye on both sides) or just cable directly to the receivers etc.

From your earlier posts, it seems you want to have satellite and terrestrial signals combined and are using a multiswitch.. these sockets are exactly what you need to cable 2 feeds to each room.

When you say, the sockets are not fitting.. are the cables you ran behind dry wall? If so, then I'm assuming the problem is that you have fitted standard back-boxes for UK/Irish-style socket fit. is that correct?

The European sat/tv socket you bought should have its own back box that would fit on the wall. But the unit can also be countersunk into the dry wall. If you look at the partially circular-shaped rear.. this will be about 45mm.. (I maybe wrong on the measurements.. so check this).. but you can use a hole saw drill fitting to make such a hole in a dry-wall and then fit in the metal body.

If the wall is wooden, you can use screw holes on the corners to secure. But there are also 2 screws on the side and metal clamp arms loosely attached by these screws. There's usually a rubber band on these to keep them steady.

When the socket is fitted into a recess hole, straightened and these screws tightened, the arms open out and clamp the body to the dry wall giving it a firm hold. Then its a case of screwing on the front plate. I fitted these all over the house. They are a dream to fit and even paint, because you just remove the plates and then then just protect the socket with a bit of masking tape.

Even the worst DIY person like me has difficulty drilling a crooked circle!

All the walls are solid, ie Block on edge or block on flat...

I think i will just get diplexers and hide them behind each TV.

i found this :
http://www.ekmpowershop2.com/ekmps/shops/melksatltd/triplex-plus-return-131-p.asp

and i thought it was the answer to my prayers, i presume that the second F connector could be used as a sat feed rather than a return path.
i tried mailing the company, but it bounced back

Diplexed plate to fit standard UK/ Irish back boxes are readily available.

II found what i was looking for on that site Rippy,

but they wont sell to me unless i'm in the trade

Have you any terrestrial signal on VHF? I ask as that diplexer won't cover all of the VHF band III.

Maybe try eBay for that kinda wallplate, or maybe tlc-direct.co.uk or other electrical outlet will sell them.

all my terrestrial signals come from Spur hill, so its all UHF

I managed to source some, so i'm all happy now..
