An antenna rotor.....that's either genius or totally insane. I'll
explore that idea.
Thanks for the ideas guys.

What about those old systems for aiming antennas on tripods from your
living room?
Is there anything like that remotely controlled that you could rig up?

Hmm...maybe it doesn't need two radios, but two antennas. Like a
spatial diversity setup.
I wonder if McCown makes parts for that.

May not be a viable solution with an 11 ghz backhaul, but you could
install two radios, once that is on target in summer and one in
winter, and switch between them without climbing at least.

When you look at the high voltage distribution lines with twin poles
they through bolt hanger connectors on the poles and then hang the
cross braces across the hangers. Poles twisting then doesn't do
anything but put tension or compression on the cross bracing...
Unless the poles actually start to lean, the cross bracing stays
pretty much immobile.. But putting two poles up pretty much brings
it to the price of a tower.

I imagine the pole would win that tug of war over time.
Looking at a photo of this pole, it has a noticeable curvature near
the top. Maybe we'll move the dish below the curve and see if that
helps.

For us they are and haven't hand problems with twisting. We've
got one with a link that's been steady for 6 years or more. The
problem is accessing the link on short notice since we don't know
a bucket truck and operators are very busy. It seems like you
could put two wood posts on either side of the pole and secure a
4x4 with large lag screws to keep it from twisting.

I always thought wood poles would be great for CPE locations but
now maybe not.

I've got a 70' (61' AGL) class 3 pole with an AP and backhaul on
it. It's
been in the ground about 3 years now.
This past spring we noticed the signal drop slowly on the
backhaul over the
course of a month. A climber went up and adjusted it by about 9
degrees,
but he said the mount was tight when he got there. This past
month the RSSI
on the backhaul has been slowly dropping again.
The humidity here tends to shoot way up in the summer and drop
in the
winter. I'm supposing this beast must be twisting as it soaks
up moisture
and then dries out again.
Is this a problem that might diminish as the pole ages, or is
there perhaps
any possible remediation? I guess the permanent fix is a real
tower or a
steel pole, but I guess I'm hoping that one of you old phone
guys knows some
magic trick. Seems like if there was a wire attached to this
pole, that a 9
degree twist would put some wicked tension on it.
