You took my response wrong. I am very interested. I have an ORION ll driving
a Ten Tec amp into a 43 foot Zerofive vertical. But beyond that, antennas are
very complex to analyze, model and, in fact, understand. I am an engineer, you
can Google me, although I did graduate several years ago. And to top it off, I
spent 45 years in the world of Digital Data Communications. But I have been a
ham since 1951, and have put up most every kind of antenna. I do know one
thing, antennas follow sound theory not witch craft or voodoo electronics.
I just wish that if you are an expert...contribute! If you are not, and have
an opinion, so state it is an opinion.

George,
If someone is not at all interested, that's ok. They can delete without
reading.
If someone is interested but doesn't understand all of this, Phil, AD5X has
a PowerPoint presentation on his web site which explains a lot of this in a
simple way, using drawings and simple examples.
Remember, this thread originated from an OM with a TenTec transceiver and a
TenTec amp and a problem feeding his 43 ft. vertical antenna.
As Jerry said, we all use antennas.
Most of us are forced to use verticals, due to space limitations.
Therefore I think this is the correct venure for this type of discussion.

This discussion needs to be in a venue where people understand antennas.

My point entirely. I suggested the AV-6110 in jest (where I should have
marked it with ;<)_)but its a real solution for those long in pocket and
short on building.
