[TowerTalk] Resonant Frequency - 40m Dipole

[john at kk9a.com]

I do not think that this will be easy to estimate plus your coral  
ground is different than the ground in Arkansas. Usually I pull my  
antennas up in the air, test them while it is hanging from the rope  
and bring it back down to the ground to make any adjustments.

If any of you have built a coil loaded 40m dipole and can remember
approximately how much higher in frequency it resonated when moved from
10-15 feet off the ground to a half wavelength or more, please let me
know.

Guess my memory isn't as good as I thought because I can't remember exactly
what happened when I built one and put it up at home a couple years ago.
Whatever it was, as I recall, was not nearly the same as my model
indicated. I've got more work to do but want to put it up soon.
