Subject: [aprssig] power poles (oh noooo)
I hope this doesn't get too much of a tirade started, but does anyone have
any info / experience with the use of power poles in a marine environment?

Poles similar to power poles are often used as pilings for piers and wharfs.
Possibly they recieve special treatment for their harsh environment, since
they are ( largely ) submerged for their entire lifespans. I would suggest
you pursue that line of thought, contact a harbor department, etc.

Not in a marine enviroment, but the one I installed in my engine
compartment of my car does get coroadded and no longer makes contact. I
have replaced it twice now and this last time used some heatshrink tubing
around it.

Subject: Re: [aprssig] Coverage between Oklahoma City and Little Rock
I spent a few days in OKC last month. There was fairly good digi coverage
in the OKC area (using D7 and 1/4wave magmount). However, I was
disappointed to see that only one digi (of the ten I counted) seemed to be
compliant with the new n-N Paradigm. There was IGate stations in the area
too.

Finally, an intelligent conversation about Power Poles, if a bit off-topic!
Funniest thing I've heard on the sig in a while!
AFAIK, there is no special marine treatment. Typical pressure
(arsenic-copper) treated 4x4's last about 4 years in tidal areas, and rot
at the area which is intermittantly exposed to air. A power pole would last
longer, but if it were under load it would not be long until the load
bearing ability was compromised.
