I’m wondering what experiences are out there regarding small vertical array, or
beverage performance in the winter over frozen ground.
The reason for this question is that over the last 2 weeks or so, my HI-z (24’
vertical) SDR skimmer antenna at my remote QTH has shown somewhat diminished

Hi Steve
I am fairly confident that Sudbury counts as a cold place...
I have found Beverages to be very insensitive indeed to their locale and
operating conditions. (I have a total of 15, mostly phased.) I now use 4 x 50'
radials at each end, but have previously used 3 x 25'. I do not believe t
I thought I'd share my own experience with Beverages and *newly-driven-in
ground rods* in frozen soil. Here's a relevant excerpt from
