I don't care to imagine concrete blocks dangling in space or screen door
closers affixed to trees, Mike.

Neither do I.
I'd imagine a pulley in the tree which a rope attached to the antenna to
be tensioned was attached. This rope would then run to a weight on the
ground to where the HD door closers were attached.
I mean, I'd imagine that as opposed to beginning to pour concrete to
which an eyebolt with a insufficient deadman held into the concrete!
