It depends how you are measuring the reactance I guess Warren, If you are using a selective method i.e. a receiver as a null detector you should not get that problem, It it is a wideband detector sty
Thanks Andy and Tom for the suggestions. Feedline is balanced 450 ohm ladder line w/ #14 conductors. I'm beginning to think that Bill Ashlock was correct in suggesting that the extra 10dB loss is due
The way I look at it Andy, is that the coax fed dipole is an un-balanced system, so I had two antennas in parallel, each resonant on a slightly different frequency. I bet if I had used twin balanced
It would. The Hi-Q quarter wave resonator formed by the shorted coax, interacting with the reactances of the antenna could cause all sorts of issues. Compre this situation with the parallel and serie
Warren I also had a strange effect when strapping a coax fed 80m dipole at ground level for use as a 160m 'TEE'. It appeared to show 2 resonant frequencies a few Khz apart. When I strapped the feeder
