I'm always terrified of losing the thumbscrew in the grass. I wish MFJ made these with a built-in right angle and a binding post, or even just a bolt and a wing nut, at the base. On Tue, Mar 29, 2016 at 8:21 AM Wayne Burdick wrote: > Use one of the KX3's thumbscrews. We

Use one of the KX3's thumbscrews. We relieved the paint on the chassis at these points so you can use them for counterpoise wires or ground. Wayne N6KR On Mar 29, 2016, at 5:14 AM, "Barry N1EU n1eu.ba...@gmail.com [KX3]" wrote: > > Probably a dumb question, but

Hi Wayne, Yes, I do that too especially on the low bands like 30 on down. I have found, though, that with the long 9' whips, the bandwidth and SWR is low enough on 20 and up that I don't even need to use my tuners, especially since I'm normally down in the CW portions. On 15 and below the overall

John, Just like Bruce said regarding the 1899... I started at one tap position for 20M and then changed the coil tap to another for 40M. When I wrote my original note that was my 40M testing... I failed to mention in my earlier email. In this case the whip length itself isn't adjusted, just the

You can, but the better compromise if you can do it is the longest possible radiating element with the least amount of added inductance in the coil. Reason being, a very short radiating element, even when tuned to resonance with a lot of coil will have, among other things, a very low radiation

Most of the electrical length of these physically-short whips is in the loading coal. Adjusting the length of the 40m whip as you describe would only move the resonance point around within the 40m band. To move the resonance point between bands, you'd need to tap the coil. MFJ makes such a whip;

Hello All, Please excuse the amateurishness of this question, but could you get one of these whips for a low band such as 40M and use it on say 20M if you don't extend it fully? John Pitz KD8CIV On Wed, 2016-03-23 at 22:02 -0700, Wayne Burdick wrote: > "Walter Underwood

I'm glad my XYL is happy with the Little Tarheel antenna on the 4Runner. My high point with it was driving over I40 from Barstow and contacting 5Q4B in Denmark on 15M SSB. It was a good day and he was working stations all over North and South America. DX at 100 KPH. (She was driving.) 73
