Topband: Air Wound Coil

[W7RH]

Guys, I'm confounded by the complexity suggested for all band coverage 
of 160m "Top Loaded T Antenna".

May I make a simple suggestion. A simple T antenna will have a radiation 
resistance of 10-12 Ohms with electrical height of say 43ft with a Good 
ground system of quarter wave radials. By trimming the top load portion 
(both legs equal) to resonance on the high end of the band 12 turns of 
quarter inch copper tubing wound on a 4 inch ABS pipe with length of 12 
inches and three relays would provide entire band coverage when 
connected to 12.5 Ohm Un-Un transformer. Cheap generic DPDT relays may 
be used to switch resonant points and can handle legal power limit.

Just sayin...
