You are in good company with Walter Maxwell, W2DU, now silent key. Maxwell was
an engineer at RCA. He designed the antennas on several earth orbiting
satellites and the antenna on the Lunar Rover. He explained this quite
succinctly in his book Reflections (all three editions), by use of the

And the Texas Bug Catcher, Webster BandSpanner, SteppIR's, et al. All

Save one; the screwdriver antenna on my truck is tuned (coil adjusted) by the

The rest are matching circuits to compensate for the disparity of input to
That's not in the least true, but those among us fixated on semantics

You could, for example, have an antenna with a feedpoint impedance of 50

Unless the "tuner" is simply a broadband transformer, I might agree.
But if the "tuner" is an LC network, like an adjustable L n
No antenna has, at any time, anywhere in any of our lifetimes, been

Kurt,
We are not tuning the antenna , we are matching the antenna to the coax at the
base of the antenna.

I agree. I suggested a remote tuner as a K3 option some time ago, but I

Speaking of antenna tuners Is there any possiblity that the new

Walt and all,
Just one clarification (for the protection of your KAT100 and K2).
The KAT100 does not talk with any RS-232 signals. It does connect to
the K2 AUX I/O connector, but that is not rs-232 either - there are only
3 RS-232 signal lines (RXD, TXD and signal ground) in the AUX I/O

I'm planning on ordering the K3, but don't want to have to pay for two

tuners.
Any ideas?
