Wow, that was a read.


Any update to this? Any new alternatives to a quality Sigma 4?


My experience with one in the mid 80’s to the late 90’s was there was no better ground plane used in my location. It was in a 70 foot tree in the Great Pacific Northwest and held up well to the windstorms and the one and only severe icing. I wish I had paid someone to remove it when I moved away but at the time wasn’t using it much.


I did purchase a quality 5/8 ground plane with 4 radials that was installed in a 65 foot tree that has held up well. I wish I knew the name of it, met a guy at the truck stop back in roughly 2004. I believe it is 21’?

The tree it’s in needs to be trimmed as the branches are blocking the radials and the SWR which has been almost flat for years is now running about 1.8-2.0 


Probably Time for new coax (It was the highest quality back then) and if I’m going to go through the effort of replacing, probably time to expect to replace the antenna.


I don’t mind paying for something real as quality, workability, and longevity are the only  considerations. Any recommendations??
