[TowerTalk] Shortened Elevated Radials_Choke Balun Needed

[Dennis W0JX]

Jeff's (AC0C) comments are an excellent summary of the choices available for radials on 160. My main point in posting was that you can install an effective radial system for the low bands with radials that are shorter than 1/4 wavelength with little efficiency penalty and a possible improvement in radiating pattern.
I should have mentioned that an effective choke balun at the feedpoint is absolutely necessary to produce effective results. See K9YC's choke cookbook for that information.
Lastly, depending upon angle of radials and other factors, the feedpoint resistance will usually be less than 50 ohms and SWR greater than 1 to 1 at resonance. This can be remedied by an adjustable shunt coil across the feedpoint.
