Better than the fan dipole
You guys heard me gripe about the difficulties of a fan dipole,
especially with close element spacing, last week. I spent some more time cutting and pruning and rehanging and just gave up because the damn thing never had a resonance fall anywhere in the 40M band. I just obliviated all the issues by getting rid of everything except for the 135foot element, and replacing the feed coax with 450-ohm ladder line on the back of my antenna tuner (Ten Tec 277). The antenna loads up very nicely on all the ham bands, and although the patterns on the upper bands are certainly different than a dipole, they were just fine for doing some DX'ing yesterday. Lotsa fun! I had previously worried about the gotchas of routing ladder line into my shack but it really wasn't so hard. Tim N3QE |

And if you really wanted to, you could change the system resonant frequency by changing the length of the ladder-line. http://www.w5dxp.com/notuner.htm -- 73, Cecil http://www.w5dxp.com |
