Wireless Service Providers → 45g vs 25g

Hi,
I've got a 6 mile point to point link I'm doing for a small business. I have a 100 ft 45g tower but I think it would be overkill. An airfiber5 would be the biggest radio I would use. Will a 25g be enough? I'm concerned about twisting and shaking. 100ft is the lowest I can go, need to be at 110 or better ideally.

What is the wind loading in your area? You can find online resources to help you determine that. Here is a map that will give you a general idea:

Towers are subject to longitudinal bending and torsional twisting...something that you are concerned specifically about. You can combat this by using torsion arms on the 25G.

Lots of good discussion on this exact subject here:

Thanks for the link John Galt I have been looking for more info on this subject

They are are both going to twist and shake @ 100 ft.

AirFiber will mount fine on 25 as for wind loading, but regardless if 25 or 45 you'll have significant twisting of the tower. You'll need at least one set of torque arm assembly near the radio

Proper tensioning of the guys is essential for proper tower performance.

"Good enough"...isn't.
