[Hi-zreceivingarraydiscussions] Weatherprrofing amps

[Dan Kovatch]

Dave, I use plastic coffee cans. I'm basically lazy and just invert the cans 
over the preamp and tape them to the post holding the vertical. The plastic 
is easy to cut to allow cable ingress and egress.  I leave the bottom of the 
can open. I have found over the years in Ohio that humidity does the most 
damage and sealing anything results in corrosion. So now I leave everything 
open and covered from the rain or snow. The coffee can preamps were buried 
in snow and have been rained on heavily with no ill effects so far. I need 
to do a Spring inspection soon.

I do use decafe cans so the preamps don't get too 'excited' whilst catching 
DX on 160 and 80!

Greetings. . .

It's great to see Lee and Dick back in business!  Great products, great 
support, and good prices.  Has anyone come up with a good long term solution 
for weatherproofing the amplifier units at the antenna elements?  Last 
December when it was cold and I was installing my 8 circle 160m array, I 
wrapped the amps in plastic grocery bags and taped them up.  While they've 
held up surprisingly well, I need to implement a permanent solution which 
doesn't introduce excessive C between the antenna and ground leads on the 
amps.  Any ideas?
