I have one True tv box fitted and the reception is good

If I have an addtional box fitted in another room will it affect picture quality

I realse it will require 2 cables

Cheers

Hi

Not too sure which way you want to do it. Ill assume this a satellite receiver box and you want to run both tvs on different stations at the same time.

The signal can be split from the LNB off the dish and fed to the two receivers conditional that there is sufficent signal, the splitter needs to be able to do 2.5Ghz signal (from memory) and have power-pass on one of both splits. then the power needs to be shut off out of the auxillary reciever to prevent both units feeding power to the LNB. Obviously this way requires an aditional card from true, Im not going to go into alternative methods for fear of T&C breach.

An easy test to see if there will be any negative affect to splitting the signal you could add an F-connector 3 - 6dBi antennuator into the circuit to see the affect. IF there is a negative affect a larger dish or another dish would solve that problem.

Hope that helps

Cheers.
