A 1/4 wave length height IS exactly a cloud warmer.
At least 3/8 wave length height is necessary for a lower take off angle.

My experience is that 1/4 wavelength is okay to avoid a cloud warmer.
However, higher is always better for DX, aka lower take-off angle.

Greetings: My understanding is that a yagi should be at least 1/2wave
above ground to avoid warming the clouds. So, considering that thought,
how much does an antennasuffer if such antenna is 63 feet up instead of 67
feetfor 40 meters over VERY rocky "soil"? Thanks, Warren; W7WY
