CB antenna on 10M?
I have an old mag mount RS CB antenna with a 24" (approx.) telescopic
whip. It is fitted with an integral audio cable (as the feedline) terminating in (what else?) a male RCA jack that plugs into the CB's antenna jack. The CB is rated at 5 watts FM. The whip can be shortened quite a bit. Is there any reason it wouldn't resonate on 10M? Audio cable ain't RG-8/U, but is it enough to handle 30 watts FM on 10M?

Ken,
Most 11 meter antennas will work on 10 meters with just a little retuning, so it should work. The 'RCA' plug will be a problem so either change it or use an adaptor. 'Doc |

The audio cable is a problem.
Why not just buy a 10 meter antenna? Ken wrote: I have an old mag mount RS CB antenna with a 24" (approx.) telescopic whip.

That coil is designed to handle 5 watts AM. It might handle 30 watts SSB but probably not 30 watts FM. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I once bought an 18 inch long 11m antenna for RC use. It consisted of wire wound on a fiberglass rod, covered with a plastic sleeve Tam/WB2TT. Tam/WB2TT |

Is there such a thing as a telescoping helical antenna? -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

"truck mirror mount" CB whips I bought from RS on clearance last year for $1.03 (down from over $50). These can be snipped for 10M, but they are not as convenient as a mag mount.
