Do you have any info on who or where these are sold? Does they run off batteries, worms, or bird seed? I wonder if they have a solar powered model which would be cool. I have used the plastic ones he
Scott, I might have missed this but what BRAND of antenna is this? If it is an M2, take a very hard look at the gamma match. The one on my 7ele is of 72ohm cable. The cable was cut and "F" connectors
