[QUOTE="spiney, post: 193065, member: 192438"] Oops ...... Sorry, there's something i didn't say, because it seemed obvious, but might not be ..... In my Freeview guide, aerials from 1 transmitter are combined to get a stronger signal (for digital tv to work). In which case, as mentioned, the cable lengths from aerials to combiner (reverse splitter) must be the SAME length. However, for aerials pointing at different transmitters, this restriction does not apply, and then cables to the aerials can be any length! Also, when looking at wideband splitter specs, these will mention signal loss, which increases with number of output ports. But, when used in reverse as combiners, these loss figures no longer apply. The expected loss for using any wideband splitter in reverse as a combiner would be about 2dB, which is negligable. [/QUOTE]
