If you love 2nd harmonics be sure to feed them with coax and run your rig right into the feedline. 73 Rob K5UJ _______________________________________________ _______________________________________

Put your GOOD rig and amp on 3595 and put 1500 w. CW into your coax to your fan dipole and have a listen to what comes out on 7190. Have a ham listen a couple miles away. Who told you it was a good

That's all wonderful but crusades with hams are usually counter productive. I submit that a detectable 2nd harmonic qualifies as a real problem especially if it is out of a ham band. 73 Rob K5UJ ___

You can go to all the trouble of putting down "mesh" and risk having to do it all over again since that is a material and product not intended to be in contact with the ground. Or you can spend the

I wouldn't call it "some kind of stake" as much as simple doubt because what you assert is, to be charitable, unsupported by observation. How long is "a long time?" Rob K5UJ ________________________

The path between earth and radials is capacitive. The wire can have enamel or even insulation and still work fine. They don't need to be buried but they usually are. The reason is protection from da
