[Elecraft] 80 Meter Verticals

[Fred Jensen]

Coupled resonator?  I built a C-R antenna for 30, 17, and 12 when we 
first got the WARC bands using 300 ohm open-wire line.  Only the 30 m 
wire was fed.  It seemed to work well, on the rare occasions I could 
find someone on the bands.  The same technique can be used to expand the 
BW of an 80 meter antenna although there are some side effects to be 
dealt with.
