Rated 5 out of 5Â by BRABUS Works in both directions
I was after a bi-directional diplexer so that I could combine satellite, radio and normal tv and then feed them via one coax to another part of the house using the single cable runs already fitted by the builders of my house.
The Screwfix technical team confirmed when I rang them that it was bi-directional and they weren't wrong (unlike the 4 output version I had previously bought from them).
I fitted one at either end of the cable run and then connected my source cables at one and and my tv and freesat box at the other end. It worked perfectly for about 15 minutes and then is started to get interference lines on the screen but only when watching the RF output from my Sky box that was in the other room. I retuned the RF output on the Skybox and the image has been perfect ever since.
Don't bother running additional cables around your house anymore, use these in pairs and save yourself a lot of work.
