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.

Subject: [TowerTalk] Half Wave?
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
