Many of you sent advice on how to cope with beavers, and I thank you. Several
of you have asked about the environmentally correct stacked tribanders, and a
summary follows hereinbelow.
The key to getting stacked tribanders in a tree was Alec Hansen. Alec lives
upriver and is a semi-retired high climber.
High climbers make their living in a remarkable way--clambering up fir and
pine trees (many of which are 200 feet tall) and cutting off the tops. From
Alec's point of view, my trees (which are only 150 feet tall) were pipsqeaks.
First, Alec cut off the dead limbs of the Antenna Tree up to a height of 100
feet. Then, he mounted two metal brackets to the trunk, one at 50 ft and one
at 80 ft. Next, he simply hauled C-3 tribanders up to the brackets and bolted
them into place (one of the reasons I chose C-3s is that they're light). All
along, I stayed on the ground, pulled on ropes, and issued expert commentary.
I aimed the antennas to the east, which, when you live in Oregon, is where
most the people are. I decided not to rotate them, because the south and
north are blocked by the steep walls of the McKenzie River canyon.
The reason why the Antenna Tree is environmentally correct is that it's
surrounded by a community of similar trees. It started out looking like dense
forest and it still does.
To the best of my knowledge, no visitor to my house has ever noticed the
Antenna Tree. One day I took the UPS man (who has been here many times and
has never noticed any of my QRP follies) on a little walk, to a place in the
forest where you could look up directly at the elements of the stacked
His eyes bugged out.
