[TowerTalk] Class 2 and Class 7 Poles

[Rob Frohne]

Hi All,

Interesting topic.  A few years ago, I tried to obtain a 120' phone 
pole new, and all the guys I talked to said it had been years since 
they had seen one even close to that size.  One of my mentors when I 
was young, was Gale Alred, (KL7BJW, KL7JW, KL7G) who had a 117 foot 
phone pole with a railroad track up the side.  He had a cart that went 
up and down the track, and could lower the whole thing from his shack 
whenever a big wind blew (and we got them with winds over 100 mph).  He 
had antennas as big six element 20 meter quagi on an 80 foot boom that 
his prop pitch turned on that thing and year after year never had any 
trouble with it at all.

73,

Rob, KL7NA/W7
