Mine are also DXE twinlead  in a dense redwood forest with rather 
irregular terrain, and go through a lot of brush and scrub trees. When I 
installed them about five years ago, I used electric fence post 
stand-offs on trees, but after a few years most had fallen off or the 
twinlead had separated from the standoff. For several years, my 
Beverages have been supported by the brush and branches of low trees. 
They work.

A year or so ago, I helped string a single wire Beverage along a dirt 
road in Bonnaire, again supporting it on the scrub trees and brush. it 
worked fine.

Bottom line -- Beverages don't have to be ideal to work.  What DOES 
matter is keeping common mode noise out of it, and also off of the 
feedline. That means a decent transformer and ferrite chokes formed by 
winding at least 14 turns of the coax around a #31 toroid.
