Just curious. Besides using a ham radio to slide up and down various meters like 10, 6, 2 meters etc, can ham operators use 11 meter cb antennas on ham freqs by cutting or lengthening the whip/stinger, or must they use Arrl approved ham antennas? And if so, why? |

Hope this helps...
I use a Wilson 1000 magmount on 10 meter with the directions used from the Wilson page,,
http://www.wilsonantenna.com/cutting.htm
Also You can make a antenna out of almost anything,,
I have directions to make a 6 meter antenna out of those old lawn chairs made of aluminum (called a SQUALO) and it can be vertical or horizontal
I also made a 5 element 2 meter beam out of a old television antenna
Heres a GREAT project!!!
take those old rabbit ear antennas used on TV's and with a SO-239 connector you can make a 2 meter dipole for the house!!!
so basically ,,,,NO there is no limits to antenna building/cutting ,,,,just as long as it works.
Maybe the forum master can watch this thread and if there is enough interest he can make a section for antenna's ???? |

Heck over the years I have made ham antennas from 300 ribbon cable, coax cable, curtain rods, the guys on the tower, a complete 2 mile mesh fence (2m transmitter hunt), and at one stage even a tree (I think it was a Euculyptus or Gum Tree).
On the ham bands as elsewhere antennas are only limited by your imagination and the room you have to play with.. |

I use an Antron A-99 for ham bands(10,12,15,17 meters). This is marketed as a cb base antenna. Works great too. I run it through a tuner.(Lew McCoy said all antennas should be run through a tuner. If McCoy said it, I'll go with it!!)
The Antron is exactly as it came out of the box. I did not trim it, simply put it up and went to work. You can trim it if you like, but it does not need to be.
On 10 meters in the car, I use a Radio shack mag mount cb antenna. It did require a bit of trimming, but it was easy and the antenna works very well. I have worked Japan, Australia, New Zealand, Germany, France to name a few places, using this set up.
If you really want to use a very good antenna that is cheap to build then....
Roll about 80-90 feet of wire off a roll. Cut it in half. Feed it with 450 ohm ladder line to the balanced outputs of an antenna tuner.Get it in the air using trees,push up poles, what have you as high as possible. That will get you on 80-10 meters with a decent signal.
Simon said it...you are only limited as far as antennas go, by your own imagination.
