Counterpoise

Rick Dwight
I believe that most pedestrian mobile operators suggest walking away from the direction of your QSO when you utilize a dragging radial.  An elevated counterpoise would probably be the same.  Perhaps two decades ago I modeled single radials and counterpoises, and if my memory is correct I believe they all indicated that the wire should point in the general direction of your desired radiation.  The above statements assume your radiator is more or less vertical.  My (poor) models showed only a slight advantage in that direction….possibly only a very few dB.    My portable antenna for my KX1 is usually a 17 foot radial laying on the ground and a 26 or 27 foot wire more or less vertical, or an inverted L.  This is a very satisfactory portable antenna for 40, 30, and 20 meters.  However not equal to my linked dipole with an apex up over about 25 feet which is heavier and harder to set up.  Sometimes if this 17 foot wire is elevated, it will still tune all 3 bands, but sometimes I need a longer counterpoise wire to tune it up on 40 meters with the built in KX1 tuner.  Probably 2, 3, or 4 symmetrical radials or counterpoise or radial wires would be the best solution if possible.  The single radial solution is a compromise which is often enough to get you on the air and make some (good ?) QSO’s.  Rick KL7CW
