so far the discussion has only treated the effect of trees in the immediate
near field area... what about the effect of wood in the Fresnel zone?
especially at low angles the ground reflected ray will surely be more
attenuated when passing through a relatively long space of dense wood than
Thanks Frank and Uli, Today I was able to remove the insulation of the
quad driven element wire(s) and test the results. Zounds! Amazing change
as everything came back to normal. The Three element Cubex Quad is now
broadbanded ( as when I first installed it with #14 bare before i made

I've fiddled around a bit
