[Antennas] maxx-com tuners

[Chris Boone]

Yes, that exactly what I and KE5O found decades ago...we had looked at one
at our employment for our HF emergency network system..We had been using
B&W's AC3-30 antenna but the loss below 10 MHz on signal level was enough to
consider something else. Bought one of these "tuners" and measured it with
test gear.....hmmmmm constant 50 ohm load across HF.....
When we finally broke it apart (well, we WERE curious) we found the
resistors...and nothing else!!!
NO Wonder it makes a good 50 ohm load across HF...the resistor does
that...what the dipole elements get is little or nothing!!

What a rip........better to run a tuner and have a REAL signal!
