Many hams think the tuner they have in their shack,
or built into their rig, is the only tuner they will ever need.
This is not the best way to match the antenna Z and reduce coaxial transmission line losses.
John’s presentation explores a class of popular antennas
which should have the tuner located at the antenna, i.e., a Remote Auto Tuner.
Come to the presentation and learn from a professional who really knows antennas
and impedance matching with antenna tuners!
