Default 2m antenna home brew??

Ok, Thanks for the ideas.

But I want to hear some positive ideas. How can I make this work for 2m and
70cm. I don't want a 10m omni.

Can I convert this to full wave omni for 2m? And should I use the gnd planes
or not? I see the lengths of the ringos are 5/8 wave and would that be more
suitable to measure it for 5/8 wave? Why not make it a full wave?

Yes, I could easily buy one that does everything I need or want, but I was
hoping to salvage this one to utilize it to its maximum use. Or is it
rubbish? My goal is to erect it at its most useful length for 2m and
hopefully receive 70cm much better than I do now. But hopefully get better
range on 2m.

Any reason why I shouldn't shorten this ringo I have to 6ft 4in (full
wavelength for 2m) ? Any reasons why I shouldn't use the gnd planes? How
long should they be for that length omni?

Thanks

I just bought at some flea fest an old style Ringo style CB antenna with
the ring on the bottom for matching tune. Also has the ground planes and
bracket for them and the aluminum antenna looks about 20 feet long (in
sections) and about 8 foot ground planes (4 total).

What I would like to do is make a 2m full wave antenna out of it. It
looks real solid at about 6ft 4inches long with or without its gnd
planes. I was thinking of using it at this length on a 45 foot tower at
the top. I was thinking of wrapping the coax about 8 times at the top
for RF reasons or matching reasons.

Any ideas why i shouldn't or should or any tips?

Thanks

Forget it! Use what you have on 10 meters. If you were closer, I would
give you a 2-meter Ringo antenna. The vertical part is 5/8 wave, not full
wave. They are a piece of aluminum junk. The Ringo Ranger type antenna
does actually work. I have one here I use on 2.
