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.

> A curious study at my shack... I have an 80m inverted V running from house to the 2 back corners of my yard. One near one corner is a latch of banana plants. 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.
