Description to any band, 10 thru 80 meters, by a simple adjustment of the feed point on the
base inductor. It is designed to be fed with 50 ohm coax, and works efficiently for
DX or local contacts. It now features stainless steel hardware for all electrical and
most mechanical connections.
The antenna is self-supporting and can survive winds in excess of 80 mph. It is
highly portable and knocks down to an overall length of 5 feet.
