I've recently dug out an old groundplane antenna I built years ago to
play around with. I've lost all my old papers and haven't been able to
find the tuning equation for setting the proper angle of the base
emitters down from the verticle emitter to a certain freq. Setting the
lengths is no problem, it's the angle I haven't found. I believe I
originally pulled them from an old Satellite Times Mag about 15 years
ago which has long since gone the way of the wind. Would anyone lend a
hand?
