3 BAND HF VERTICAL ANTENNA
15M 20M 30M

This antenna consists of one 15meter bumpermount coil antenna and the bottem and middle section of a old discarded 11meter antron-99.
the bottem section of the antron-99 useally the wire inside breaks clear,so since it is broken clear from the top solder point,the fiberglass shell is now serving as the insulator for the antenna.
a seperate ground wire is run from the shield of the coax to a grounding rod, while the center conductor of the coax now gets connected too the bottem bolt of the middle section of the antron-99, you could make the connection were the two sections screw into one another.
