Improving airband radio reception

said in rec.radio.scanner: The loss will be considerable. Yagis are quite narrow band. For a few bucks/pounds/euros you can buy some aluminium tubing from a hardware store and build your own. Or look for "broomstick and wire hanger" designs on the web. If you have a long enough piece of wood for the boom and a few wire hangers it'll cost you nothing and still work as well. Or you might look into building a quad - more gain with less antenna. |

Hi
I liked the idea of the 'broom stick and coat hanger' antenna, but have strugled on the practicalties. I went through the design he http://k7mem.150m.com/Electronic_Not.../yagi_vhf.html and ended up with a very large (about 48" square) antenna that still complained it was to short and the elements too thin! It also doesn't explain the driven element connection details. Help please :) Cheers Kev |
