Folks, I'm starting to get ready for the upcoming winter frolics on 160. The 160 antenna is a sloper and I have somewhere around 50 or so 130' radials pretty much buried under 6-7 years of leaves. When I went to the remote coax switch & checked the readings on the sloper with 10' of coax, I found some readings with the old MFJ-259B that concerns me.
I thought I'd cut the Sloper at 129' long for best SWR at 1.825 but I'm now reading the lowest SWR at 1.737 MHz and the impedance read 85. Going back to the shack I read the antenna (with 360' of 7/8 50 ohm commscope now in-between), and the resistance drops to 55 but the SWR still reads lowest around 1.737 It appears I need to shorten my antenna, I'll have to work out the proper length again but my concern is why at the feed point would I see 85 for the resistance at resonance. Suggestions on what might I give a look to when I go back out tomorrow? Thanks & 73, Gary KA1J _________________ Topband Reflector Archives - http://www.contesting.com/_topband
