Hi Guys, Thank You for all the wonderful ideas on getting my 160-m. Inverted L tuned. Your ideas got me going! My first mistake was connecting the radial ground to my tower ground. Here's what fixed
Great - Glad to help -- You might try a few extra radials, also, as I believe that will bring the SWR down naturally. It does for my vertical monopole. Happy trails. == Richards - K8JHR == UNUN and =
Hi Richards. Wouldn't adding more radials bring up the SWR? 73 Tom W7WHY _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTa
Your last post came in just as I was about to send this one. I see you found something that lowers your SWR. I will go ahead and send this anyway, so you can see what was causing the problem. Assumin
ER... ah... um.... In my experience with a large vertical monopole antenna, adding more radials seems to bring SWR down. As for the correct answer in theory... I am not entirely sure. I based my advi
There is a scenario that you are both correct: If the large vertical has quite high ground resistance in the beginning, the base impedance can actually be greater than 50 ohms. As radials are added,
Hi Richards Yes,in some cases--maybe :-) If you have a vertical, with just a ground rod, you may have a great SWR, clear across the band. Some people think that is GREAT! But, it probably means you
Makes sense when you say it that way. The good news is that we all seem to agree the guy needs more radials. Thanks for the uptake! == Richards -K8JHR == == == _______________________________________
We did a test here with a vertical cage antenna. Started with four quarter wave radials. SWR was 1:1...every weekend we added four more radials. Each time the SWR went up and the input impedance went
