I have come across a problem today splitting a TV Aerial, I have split many TV Ariels in the past without a problem until today. I took the fitting from the back of the TV and put it into a 2 way Y splitter and then added another Aerial to the splitter also but then I had no signal at all so I thought maybe the splitter is duff so I simply joined the wires instead as I have done many times previously with no problems and still no signal at all which has intrigued me somewhat. The only way I can get the TV to work is by fitting the Aerial directly into the back of the TV, if I try joining the wires or using a splitter I get no signal at all. I have also tried one of those in line joiner pieces and no signal there still. Why havent I got a signal if I simply join the wires as I have with my own tv's in the loft where I have 4 tv's working without a problem?
