I am just about to finish my barn conversion and have istalled coax from each room to a central cupboard where I intend to put a tv splitter. I'm not allowed an aerial but my friend next door says I can put an aerial on his mast. I have a few questions if anyone knowledgble would care to help. 1) Will another aerial effect his signal in any way? I intend to put mine about a foot below his. 2) Which is the best aerial for DTT? Am I lookinng for the highest gain? I'm looking at Maplin item XQ42V but is there a better one? Edit: Just noticed this is an Antiference aerial. There are higher gain ones in the range, would they be better? 3) My transmitter is group C/D, Should I get a C/D aerial or would a W (Wideband) be better? 4) I will get a masthead amp. Should I go for the most powerful? Maplin sell 2, one 23db and one 13db. Will the most powerful have any negative effect? 5) I intent to use FT125 cable and the distance from the splitter to the amp will be about 40m, is this too long? Thanks in advance.
