Thankyou. This is good, it sounds like the basic plan will work then, and I
might be able to get some chicken wire to cover at least part of it.


Chicken wire rusts out pretty fast.. You'd probably be better off just
scrounging some AWG20 copper wire and improvising a little grid or
randomly laying it out.

One other thought... In that USMC antenna manual there is a mention of
something similar, a 15' whip tilted and also tied back so the upper part is
almost horizonatal, it's intended as a way to use short(ish) distances for
skywave propagation. It looks useful given the context of trees and buildings
within 100m of my best mounting point. What I'm not sure of is whether the
curvature of their tied antenna is relevant, or a straight tilted whip would
have no significant differences.


Curvature isn't "significant", and for a lot of cases, the tilt isn't
either. But, tying the whip back does keep it from whacking too hard on
low hanging branches.
