Hi Ralph.  I think the dialogue here has confirmed my suspicion that I/ we have nature induced swr rising.  😀
I’ll make an extension for my pole cutter and see if I can get to the 25’ branches this weekend.  Ugh.

I cut them to the ground after the any freeze and have a nice swr.  As they grow my swr changes and I retune after a month.  The capacitance of a plant full of water off the side of the wire has a major impact.
