As I sit here not participating in the Jan VHF QSO party partially due
to a cold but mostly due to freezing rain, I wonder. I wonder what
stories and advice the group has about this sort of situation on VHF and up.
What sorts of design and fabrication details work to make antennas
perform well in environmental extremes?

Up here in Alaska we use covered Rotators, Bearing Shields, Low Temp
Freezer Grease, and heated Radomes to keep things working clear down in
the -60F range. Freezing Rain means you just have to keep the rotator
moving back and forth, every few minutes, to keep the Ice from building
up on the rotary sections....
