[AFMUG] Wooden pole twisting

[Adam Moffett]

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.
