55 ft antenna, with radiation patterns in horizontal plane and a plot of impedance for the 7 ham bands. The data points in the latter are the frequencies where computations were done. For the impedance plot, connecting lines drawn thru the intervening non-ham frequencies should be ignored.
|W8JI 55 ft doublet|
66 ft antenna, with same plots and same feeder & height above ground.
|W8JI 66 ft doublet|
Radiation patterns for vertical plane are not included here, but are readily available.
