Re: Topband: Some experiments with a short beverage, not succeeding very well

Mystery solved TDR mode on my AIM 4170 revealed problems with the coax that I did not know were there. All working good now, thanks everyone for the help! Mark Lunday, WD4ELG Greensboro, NC FM06be wd4...@arrl.net http://wd4elg.blogspot.com SKCC #16439 FISTS #17972 QRP ARCI #16497

Topband: Bent Beverages, BOGs, and about those gutters...

Topband gurus: I'm a very active lurker here but try to keep quiet so everyone doesn't know my lack of lowband skills. This weekend's Field Day has me itching to get back into lower bands again. ( I had burned up/out doing 26 hamfests a year hawking 'one of those SDR radio companies'.) I had to

Team I have installed the new ground rod and I am using a pre-amp at the feed-point. I will measure the SWR over the weekend after work calms down. Mark Lunday, WD4ELG Greensboro, NC FM06be wd4...@arrl.net http://wd4elg.blogspot.com SKCC #16439 FISTS #17972 QRP ARCI #16497 _

Re: Topband: Some experiments with a short beverage, not succeeding very well

Hi Mark, After following this thread, and assuming that your coax connectors etc. are properly installed, I strongly suspect that you need to improve your RF earth ground. Its resistance is likely too high. Add some random-length ground radials, about 4 or 5 of them running from the rod in

Re: Topband: experiments with a short beverage

Hi Greg, Four to six feet is not too high for a Beverage on 160 through 40 meters Beverage sensitivity improves gradually with increased height and th rear lobe and sidelobes increase (directivity degrades) gradually with increased height. The only Beverages I ever installed lower than

“How does a 250 ft long, BI-directional beverage even work? Thats only .5 wavelength long on 160m, and only 1 wavelength long on 80m.“ At my QTH a 300’ unterminated beverage at 3’ is FABULOUS on 160 meters. It’s a true marvel. I can hear signals buried in the noise on my other RX
