So will someone post a simple rule of thumb. If you have the option of
optimizing cable length from PA to first cavity, IE you haven't made
them yet what's the best "simple" rule of thumb to follow to build them
to avoid reactance. 1/2wl if allowed minus coupling loop depth? Or is
that past a simple thumb. Also, This will obviously not work well for
220 or 440 or a most vhf repeater setups. So what would the next ideal
cable wl be? And so forth. The reason I ask, if your building new cables
why not? Answers on here seem to range a lot.
