Currently replacing a twin 1 gang aerial wall socket, however im having problems with one input signal being shared across both sockets (even when the second feed isn't wired up). The previous socket had two completely seperate sockets, however this new socket, the grounds/shields seem to be connected together (ie: the two input feeds shields are bridged together via the shield clamp) As well as that, i've noticed that the shielding on both of the aerial feeds (one from a loft aerial, one from a booster amp connected to cable box downstairs) and the centre pin (not sure what the actual name of it is called) seem to be shorted (connected together, buzzed it out using a digital volt meter). Because of this, it's causing both of the sockets to short.
should the sheild and centre pin be connected? Do the shields need to be connected at all, good i just have the centre pin going to the socket and leave out the shield clamp etc? Any help would be appreciated

At home we have the main aerial going into a 6 way splitter. Each room then has it's own cable running to that room connected to a wall socket. Some of the bedrooms just have the cable direct to the tv for the time being.
Works fine without the need of boosters. Running freeview in all the rooms too and the sigal is 90% - 98%.
Maybe you need to upgrade the aerial?
Maybe the booster is sending back a signal corrupting the signal?

no it's nothing like that, i have two seperate feeds to my bedroom, one from a booster/splitter (which is the cable box signal from downstairs) and another which is from an aerial in the loft.
Eitherway, i've tracked it down to the socket im installing (the twin aerial socket), which bridges both of the shields and in turn basically connects both of the feeds together (with both of the sockets just being spurs), which gives you lovely interference on the signal.
So im going to be ripping apart the circuit thats within the socket and modify it a little.
just a little bit miffed as the socket was £20 quids worth

John's the man for such questions tbh, he could fit an aerial in a tree house with a packet of chewing gum, 3 resistors and a golf club.
