Below are all of William 's postings, with the most recent are at the bottom of the page.I only get 18v at the master aerial point when I switch the sky box on and the sat cables are connected from wall to box when the sky box is switched off or I take the sat cables out the box I get no voltage at my aerial

Is the 18V going back towards my aerial when the box is switched on not a back feed through my sat cables into the triplexed unit as the voltage only appears when there plugged in and the box is powered up.

When you said the sky box sends 18V DC to the LNB for polarity switching purposes is that not why I am getting the voltage on my triplexed unit as its a combined unit hence the reason for the isolated coax point in the room

jb38 with regards to my bedroom coax plate which is isolated with a capacitor on it when I plug my main aerial into return on my living room wall plate I get roughly 18V on the bedroom cable ( no voltage at the front of the plate ) but when I take a cable from RF2 to return I get roughly 9V on the bedroom cable

But remember I only get a voltage to my main aerial cable when my sky box is switched on as if the back feed ( 13 to 18V ) is going back up the sat 1 cable into the triplexed module which is joined with the main aerial output marked " TV " and that's why when I take the main aerial cable into my " aerial IN " port on my sky box it cuts the sky signal ( without the attenuator ) but with the attenuator and through the box into return via RF2 I get both freeview and sky signal but only Half the freeview channels its strange

The return output is a separate module/cable at the back but it is part of the master wall plate

Lastly I don't realise why now when I loop a flying lead from TV to return ( the way it was before sky was even installed ) The main aerial menu on my bed TV now is gone where u go to tune/store channels etc but I can still get all my channels
