[TowerTalk] Crankup Danger

[Bob K6UJ]

Me again,
How do you guys with the motorized towers block your towers ?  I am thinking of using 1 inch water pipe.
And where do you block it ?  Since it telescopes, do you you put blocking through every section ?

I am subject to FAA concerns if the tower is tall enough (red and white alternating paint and lights.)  I do have neighbors but the nearest are 1/4 mile away and not in the “kill zone” of anything I would put up. I have a small black Angus cattle ranch (cow-calf operation) on 160 acres so I can get pretty wild with sky wire and such if I want.
