My 49 years of antenna useage has taught me it is bad to bring the high voltage end of the antenna down close to the earth because of ground losses due to the capacity of the antenna to earth. Not to mention the high RF voltage induced into the shack. My center fed antennas have all worked muc

Hi Steve, As long as you mentioned the inverted vee, I thought I'd offer this to think about. I have been using a 20m center-fed inverted vee with very good results. And here's the great thing about it... it's a coil of TV twinlead. One end of the twinlead is split to form the two arms of the

Steve, If your tuner is of the L network type (like the Elecraft auto-tuners), it will have a difficult time matching the high impedance of a half wave end fed antenna. If you want something similar, use the W3EDP length antenna - an 85 ft. radiating section with a 17 ft. counterpoise wire in pla

This may be silly question? I'm trying to cut down on set up time and weight for my backpacking journeys into the field with QRP gear. The end fed halfwave or random wire 'sounds' good to me becasue of the no feed line and a simple LC tuner can be used. Opposed to CF halfwave with balanced tuner (
