I have an 8-circle array in the woods. The tallest trees in my area are about
60-70 feet, so your trees might be larger and denser than mine. However, my
system works very well, judging by the fact that its pattern seems to match
very closely the theoretical pattern for this array. In other words, I
seriously doubt that the trees are detuning or degrading my array in any
significant way. Some people believe that trees and foliage introduce
attenuation, even on 160 meters, but as long as the attenuation is the same for
every element in the array, it is of no consequence because these short
verticals are already very inefficient. I do try to keep the verticals a few
feet clear of big trees and foliage, and periodically I trim away foliage that
grows in around them.

Subject: Topband: 4sq vs SAL 30 Mkii in a forest
Hi all, newb to the topband 160 reflector here so thank you for any coaching or
corrections on protocol…
I live on a heavily forested (douglas firs - almost all of which are 100’+)
piece of land.
I have enough room left to put up either an SAL 30 or a 4sq of 20’ verts with
80’ spacing. HiZ probably
Problem is regardless of which I choose, there will be at least one or two
trees in the “infield“ and foliage around the edges.
Any experience with the same or thoughts? Grateful for the coaching please
feel free to reply direct to mikebfischer@comcast.net
