Sky signal help!

Hi

I am trying to setup my new home so that I can have the sky+HD box in either one of two locations (the box may move, but only 1 box used at any one time)

I have a twin feed from the LNB (this feed is fully working), which I have snipped half way, installed 2 satellite 'y' split adaptors and continued the existing cable to the furthest socket. I now have no signal!

If I disconnect one of the inputs and outputs from one of the splitters and join the connectors (using a f-connector coupler) I get signal on input 1. If I put these 2 cables back into the splitter, I get nothing.

Am I correct in thinking that the DC power is not passing through the splitter? (assuming this, I have tried swapping around the 2 outputs to see if one passes any power, still no joy)

If this is the case, and I can purchase a splitter with DC pass, does the sky box output DC on both aerial inputs? If not, would I need to get a splitter with DC pass on both outputs, and always ensure that this line goes to input 1 when in both positions? If not do I have a problem and will I ever get this to work?

Thanks in advance!

Do it properly - run two sets of cables from the dish to the two locations. Sooner or later you are going to want to fit a second box.
 
The LNB is an 8-way and it is all full to the rest of the house. So not an option - and really want to stay away from having 2 boxes and spending our lives in different rooms!
 
In which case, just put a small IP67 box on the wall and swap them around as and when you need to, splitters, even the ones which pass DC on both legs, will attenuate the signal by 5db or more. _http://www.satelliteandaerialsupplies.com/product/?s=konig-2-way-f-type-splitter-5-2400mhz-vhfuhfif
 
Thanks for that. Am I correct in thinking that only aerial input 1 will send the DC voltage to the LNB? In which case, in both locations, input 1 need to go to the same splitter?

In real world terms, how much is a 5db drop? Presumably not too bad as long as there is moderate/good signal strength to start with?

Thanks

No, you're incorrect, both inputs send a voltage to the LNB, 13v for Vertical channels and 18v for Horizontal to switch the polarity.

So you need to split each feed and send to both rooms, so that each room has both feeds. 5db can be make or break in bad weather, particularly if the cable runs are long in the first place.
