Gary,
Everything Bill says is true, however, it may not be important. Yes, if you
have a high SWR on coax your losses will go up. The best place for an
antenna tuner is at the antenna feedpoint. It isn't the most practical
place however. My antenna tuner is at my operating position. My
transmission line is ~100 feet of 1/2 " coax, RG-8/u size. On 40 meters it
has a reasonably low SWR. On 20, 17, 15, 12, and 10 the SWR is quite high.
It works fine for me. If I was serious about the higher bands, I wouldn't
use this vertical, I'd put up a small Yagi. I've never considered a remote
antenna tuner. I just don't think they are worth the price.
My suggestion to you is to stick with a good manual antenna tuner at your
operating position and use 1/2" diameter coax such as RG-8/U to the antenna.
It will work great on 80,40 and 30 meters and will be more than adequate
through at least 10 m. It will easily handle a kW on the lower bands and
a100 W through 10 m.
