[QUOTE="Analoguesat, post: 947914, member: 176362"] Welcome to the forum! :) Shame you didnt ask us a few months ago - we could have advised you with the cabling you needed. You can use passive splitters to split the cabling but its not going to work satisfactorily long term. Consider this- the lnb is an active device which responds to a combination of voltage changes & 22khz tone bursts to switch to one of four possible states with the band (hi/lo) and polarity (H&V): 13v tone off 13v tone on 18v tone off 18v tone on State 4 will trump all the others if one box switches to a channel using that state and no matter what you do on the other box(es) you wont have a signal. Unfortunately sooner or later someone is going to switch the second or third box on at an inopportune time and and the big film or football match in the living room is going to go off at a critical moment! :D Or you are feeling lousy and stay in bed - you want to put the news on & find someone has left the living room box on a shopping channel & no signal for you. At the end of the day its still going to be best to do the job properly - can you run cabling round the outside of the house for example - if you use cables that are similar colour to your brickwork you can hide them fairly well.
