Re: [TowerTalk] question Rohn 25 wind load capacity/thanks

Thanks for all the responses!
Consensus is I should go with 55G if possible, and 45G as a minimum.
Too risky to put that much antenna on 25G but I may keep the 25G for a smaller 
setup in addition to the heavier duty tower.

73 to all and stay safe,

Subject: [TowerTalk] question Rohn 25 wind load capacity

Hello all,
I'm planning a Rohn 25 guyed tower, at this time likely 120ft or 130ft.
At the Rohn site, it appears wind load limit for a 120ft 25G would be 17sq ft.
I will likely put up a C31XR on top and a 2nd C31XR sidemounted at around 60ft.
This is about 20sq ft wind loading.
Is anyone using this configuration with Rohn 25 ?
Alternately I could have just the C31XR on top and add a 2 el 40m shorty yagi. 
This would be right around 17sqft.
I already have almost 200ft of Rohn 25, so was hoping to use that.
However, I'm thinking I may need to sell it and buy Rohn 45 or 55 to go with a 
pair of C31XRs and then possibly a 40m yagi as well.

I know this can be subjective with many opinions. One local ham has had a TH7 
and 3 el 40m KLM up for almost 30yrs on 100ft of Rohn 25 without trouble, yet 
I'm sure that exceeds the recommended wind load.

Thanks and 73 to all, hope you found a vaccine shot if you wanted one,
NJ was not bad, got my 2nd shot in mid-Feb,

Darrell AB2E
