    Dumb ???? #3 (about radial length)

    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.

    Dumb ???? #3 (about radial length)

    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...

    Dumb ???? #3 (about radial length)

    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...

    Dumb ???? #3 (about radial length)

    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.

    Dumb ???? #3 (about radial length)

    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...

    Base Beam Antenna Question

    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.

    First thread and need help.

    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.

    Yet another dumb ????? (about TOA's)

    Yet another dumb ????? (about TOA's)

    Thanks, Henry. That helps a lot. I got another question. On your plots above, am I correct in assuming that would be a side view of a vertical antenna? I never saw this kind of stuff 40 years ago, and am still learning. Thanks, John.

    Yet another dumb ????? (about TOA's)

    So.... I did "Google" it. I did read the TOA myths, for the third or fourth time. Based on the description of TOA in that article, I can't see where you can have very much of a change in 20 or 40 feet of height. Maybe in miles, but not feet. I imagine a teeter-totter with the fulcrum at 20 to...

    Yet another dumb ????? (about TOA's)

    See, I learned something today. It still don't seem right to me..... but, I'm old, now. It's been over 50 years since I needed Ohm's Law (or, what the color codes on resisters mean). ARRL manuals are your friend. Thanks, John.

    Yet another dumb ????? (about TOA's)

    Quick question that I don't know the answer to. If you change the down angle of the ground plane radials IE: 90*, 45*, 20*, does that change the takeoff angle, significantly????? I've seen it discussed about impedence IE: 90*=36 ohms, 45*= 50 ohms, and ~20*= 75ohms, but, not weather that...

    How to: push-up masts

    FYI, I ordered a small 22foot ez-up today. It's got to be easier to push that straight up than trying to wrestle the antenna, coax, and 10 feet of mast on to the top of another piece of mast. Now, to find some help to get my old temporary (30years!) antenna down. Thanks, John. PS: Mudfoot: I...

    How to: push-up masts

    Thanks for the Puppy pic's. Gotta luv it. There is no radio club in this town. There is no other CB'er in this town of 700 people. Advantage: I never have bleedover. The exception to that is some of the stations on the east coast, over a thousand miles away. Can you believe 5 channels either...

    How to: push-up masts

    Prolly be steel, if I get one. Maximum antenna weight is a Sigma 5/8 Venom, plus LMR400 coax. 5 or 10 pounds??? ( I don't know if I'm strong enough to push/pull that much weight + pole) I'd be about 7 or 8 feet off the ground, standing on the deck. I guess I would be pulling up. Maybe. I...

    How to: push-up masts

    This may seem simple and a no brainer. How the heck do they work? Do you stand the base, and then push up the rest? For the hundreds of you who put them up and down all the time, gimme some help here. Inquiring minds want to know...... Thanks, John.

    How to: push-up masts

    For my second post, I'm gonna ask a question that I don't know the answer to. I've only owned one pushup mast in my life. 50 years ago we stretched it out and locked it down, then tilted the antenna up. Is there another way??? Now I'm alone, so if there is an easier way I'd like to find out...

    5/8 wave starduster?

    Hey, the original question has been answered. (waste of time unless I'm bored) I'm still gonna put one up, at about 10ft, just to see what it does. I'll get the old antenna down when it warms up (snowed yesterday), and I can get some help. That will be younger people, when not at work. Older...
