[TowerTalk] "Antenna Tuner"

[WA3GIN in King George, VA]

Dave, with ipmost and all due respect those mentioned auto-tuners do NOT 
adjust the resonance of the antenna... they are purely impedance matching 
devices... some do understand the terminology and the physics ;-)  You can 
dumb down the tech talk but that doesn't change the fact...K
