free standing pole for antenna to receive broadband access
 

I need info on building a free standing 50 foot pole. It is my best
alternative to get broadband internet access.

I am concerned about lightning and sway.

I am thinking about using steel pipe, in sections, set in a concrete
base with a rotor on top of the pole.

Hi Larry,

This pole is called a tower.

Hi Larry- If what you really ment was a "Utility Pole" aka power pole, telephone pole,
then once you have it planted, and you wish to mount a rotor on it, can be done quite
easily, as long as you have the bottom pipe mount for your rotor. at the top of the pole,
you will need to drill a couple of holes thru the pole , useing 5/8 bit. Next: you
need a chisle - notch about 1 inch deep notch in the pole, perpendicular to the pole
(horizontal) Now get couple of pieces of 5/8 inch all-thread- if you are good with
a torch, bend a section of the all-thread into a circle, slightly bigger than the pipe
to support your rotor (or find a metal smith to do it for you) and be sure to weld
the end of this loop to the part where the circle started to be formed. On the notched
end, insert your all-thread - DO NOT USE A WASHER! on the un-notched end, use a washer,
and nut. Run your pipe thru the loops of the all-thread, then tighten the nut on the
allthread. as the loops suck into the notchs of the pole, it will pinch your support
pipe, and becomes quite tight! and will support at least couple hundred pounds! Another
tactic used is get the mounting hardware from d.b. products for their db-222 antenna
this will allow mounting a pipe to a pipe- now what you want is thrubolt to pipe.
one of the looped pieces needs to be replaced, with a piece of channel iron, drilled
to mate the rest of the mounting hardware parts, and then drilled thru the center for
your thru bolt. Have seen these hold up with several hundred pounds of ice and not break!
And, be sure to run a GOOD ground to this mount, for lightning protection! as info,
