Thanks for all the inputs, much appreciated.

Maximum run length for the 75 ohm cable would be 1/4 wavelength on 28MHz. For other bands just a couple of feet as a series section transformer in each case.



if you're running it as a transformer, you need to look in detail at the current and voltage along the transmission line - it's not a "matched line" situation where voltage and current are basically constant along the line.
