Hey Chris,

Sorry to bother you here on the Forum. I have been unsuccessful in reaching you at chris.sisler@rfarmor.com.

I need certified engineering drawings of the NPM30WM mount. Our county now requires a certified engineer to sign off on any broadband facilities that they are structurally sound. I checked with Yoder Industries as their name appears on the installation diagram, but they said you were the owner of the intellectual property which included the engineering diagrams.

Thanks in advance for your reply.

I would suggest using the rohn 25g roof mount then for installations in this area. Got to love CO and their regulations.

Where as this is designed to be stronger than the rohn 25g roof mount which is now only 25' which if you have climbed on both you can tell ours has less sway and is more rigged but we never paid for the certification seal as they wanted far more money then we have profited from sales.

In all the years we have sold less than 100 units with a profit of about $200 if purchased through a distributor and about $450 if direct sales.

The seal would have cost over $50k


The base provides more stability then if cemented in ground and we instruct user's to follow wind loading specs of free standing non guided rohn 25g at 30' as if cemented in ground.
