Most HOAs don’t even understand all of the ways that antennas can be deployed. All of the ones I have read specify prohibiting free-standing antennas or specify the length/width/height of antennas above the rooftop. I read very carefully and there was no restriction on my very long L shaped 80m water droplet collector that I had strung in my trees. If asked, I would say that I am making sure that the trees are structurally sound.
In fact, if you raised a tower 1 inch above the ground and banded it to a tree, you would be in compliance with your HOA, since it is not free-standing.
