So.... I've been thinking about this for a week, and wandering thru a lot of websites. I found that "the DB" (on another site) agrees with you at .99. Using .1 wave, I got 36" (1/10 wave), for the placement of the RF choke. Using .15 wave, the answer was 54" (1/8 wave). I think that the next...

OK, got everything but that...... What the heck is a Lambda???? I made an assumption that the VF would have an effect on the coax. I don't see that it doesn't. Are you saying that coax shield has no VF? How can that be? And if it does, then wouldn't having a fraction of a wave length make...

Thank You. That is it exactly. John.

I don't know if you're interested but I have Lou Franklin's CB PLL databook and, Understanding & repairing CB radios. I'd be willing to let them go for cost+shipping. The books are in excellent condition, as I'm not smart enough to use them. John.

As for today, I got the antenna down. Much easier where I have it now, as I can do it by myself. I also took down the mast. Replaced it with a EZ-up 22ft. Now it's even easier. I took down the Skipshooter, and put up a Semi-duster. That's a Starduster that I drilled and tapped out the radial...

Several days ago I was reading a post on these forums of a guy looking for books by Lou Franklin. I believe it was a member named "715". I can't find the post again, and I don't know how else to contact him. Any info welcome. Thanks, John.

I re-read your post for about the 10th time (I'm, slow). Increasing the length will cause the efficiency of the antenna to go up, and that's all. The rf choke should make no difference. Is that correct? Thanks, Again.

Henry, If I understood what you said correctly, the only way that the Chicom 1/2 wave can "get away" with using three 30 inch radials is by also using the mast and coax as part of the ground plane. That also allows it to "cheat" the antenna in to thinking it's 50 ohms. Is that correct? If I were...

Jeff, Imagine, if you will, a 7ft Skipshooter mounted on an "L" bracket (to clamp to a pipe). Between the mount on the "L" bracket and the Skipshooter is a workman WIL-KIT-B six element (about 6 inches long) radial kit that uses 3/8x24 threads for mounting. It's obviously a cap-hat of some kind...

Once again, I don't think I explained myself very well. Is there a relationship between the length of the radiator and the radials? Can I lower the SWR by lengthening the radials? How about by drooping them? My 1975 ARRL book doesn't tell me. Thanks, John.

I finally got my 30 year old temporary (?) antenna down. I then spent about 2 hours taking apart/breaking the old antenna- a 1/4 wave radioshack with a Francis hotrod 5.5ft as the radiator. After 30 years it did not want to disassemble. Anyway, I then put up another home-brew antenna made from a...

Wandering websites tonight. Mosley deviant 1 on ebay, $230ish, used. John.

Hi, The driven element will be the one with a match (gamma,beta), where the coax goes, on it. The reflector will be about 5% longer, and not driven. On a three element the director (front) will be about 5% SHORTER. Point the driven and/or director element at who you want to talk to. HTH. John.

If you have a VOM (volt ohm meter), check the wires in the mic from the mic to the connector. A broken wire is usually where the coily cord goes in to the mic or the connector. That's where the cord bends the most. HTH, John.

ya know, sometimes I feel like I'm chasing butterflies, with a cannon. John.
