Gang, It's been way to quiet here. With fall only a week away and winter not too far behind, it's a great time for antenna work. I'am going to out up a off center fed dipole. After reading pages afte

Mike, Probably nobody on the planet has built and tested more different versions of the OCFD (Windom) than I have. I can give you a few pointers here that you don't read on the W8JI Windom page. I go
Rick and the group I've been to your site, but didn't see any dimensions given. I may have overlooked them. I dropped $100 for a comtex W2 jerry someone balun. I figured a 4:1 balun is pretty much th
Mike, You cannot buy the right balun at any price. PERIOD. I pointed out the two mistakes most balun manufacturers make. The comtex balun you bought (built to Jerry Sevick, W2FMI) is insufficient. Th
Rick, I hate to be a wet blanket, but off-center fed antennas produce VERY high common mode voltage/current, enough to fry a very good ferrite choke with as little as 100W. Running a power amp is rea
Back in 1997 I bought a OCF, which was called a TNT Windom made by Antennas West, that I still use today. It is 135 feet long has a balun & isolation choke made of ferrite beads. I don't know what ba
Jim, (and all others), Before reading below, let me say that I deem Jim to be one of, if not "the" world's top authorities on baluns and CMC. He has been instrumental in my learning before doing my o
But Rick, the common mode current varies along the line, just as it does on any antenna. I suspect that you measured the current at or near the shack. That is VERY different from what it is up in the
GM Jim, Now we are getting to the interesting part! (hi) I would suggest others not interested in this topic simply hit the DELETE key now. This is a VERY LONG RESPONSE. Fundamentally, ALL of the ass
Mike, I am late in picking up this thread, nevertheless I went through the OCF dipole fever, modeled like mad (EZNEC), read the literature, and like all of our antennas you have fans for everything f
*Well my guess is that I am about to get really Slammed. We have used several OCF Antennas. At 100 Watts, things are pretty good. My problems appear anytime we try to go QRO. At a Kilowatt there does
The antenna Im planning on installing, the off center feed dipole, will be replacing the 132 on a side center fed zepp feed with 600 ohm open wire that up there now. After all the work I put into thi
Kris, Sounds to me like you didn't do your homework. (this is not flaming, just a statement of my opinion) Part of your problem was the choice of balun. The other part was the position of the feedpoi
Ha Ha, love that Wade! I don't want to fry anyone. My goal here is to help people understand how to use these antennas in a safe way that will not fry them. First of all, let's ALL agree the definiti
Mike, You were a bit vague on a few points, making it difficult to 2nd guess the problem. 1. When you say your openwire fed dipole (OW-FD) dipole "won't perform", what do you mean by "perform"? Do yo

Jim, Congratulations on your excellent placing in the contest. Somehow I just can't get interested in low band contesting during the summer. Once it turns cold (which is about a month away) I will co
