TV Aerial Socket - Splitter?

[DrC]

Hi there - Quick Question about my TV aerial if you'd be so good. We have a loft mounted aerial with a coax cable that is chased into the masonry and comes out in the lounge. The faceplate that is attached has 1 input from this cable and 2 sockets on the front - enabling us to plug in an FM aerial as well as the telly if we so wish. Now, given that when an aerial feed is run through a Y-shaped splttter it effecticvely halves the signal strength down each subsequent wire, is the same effect happening in this instance, even though we on'y have the telly plugged in.?

Would replacing the faceplate for one with a single socket be a simple way to double signal strength to our telly? On freeview channel 5 we only have 8% strength and 50-60% quality so we're having to put in an aerial booster to make it viewable.

And if anyone knows how a correctly wired socket is supposed to look it would be grand if a piccy could be posted. It all looks rather messy in there.

Many thanks in advance.

The idea of the FM socket, is to feed link the tv & radio in the loft, send it down the one cable & then separate it at the room.
If you have no radio aerial you have only uhf at the socket.

There are two aerials in the loft, both feeding into a black box (have not investigated what is in there but assume some sunning wire joining device).

From this comes 1 coax cable that terminates in the lounge. Funnily enough, the signal strangth for the telly is about the same whether it's plugged into the TV or FM socket in the faceplate.

So it looks like you have an FM ant in the loft, I think these usually join with a Y connector, maybe its just been hard wired.

So you should get FM out of the FM socket.

If you want to increase the output. I think you need either a better
aerial
different location
or amplifier.
