ROHN FR25G Flat Roof Mount Base for 25G Guyed Tower on Building
Made in the USA!
The ROHN FR25G bolts directly onto a Watertight and Reinforced Flat Roof Surface for a 25G Guyed Tower, but Cannot be Used as a Self Supporting Base Plate. (see 25GSSB or 25GBRM) Roof Mounted Tower Options may limit Potential Height considerably as there is no Wind Load vs. Height Guidance to be found this type of Mounting in any of the Specification Literature for good reason. You need to Consult an Engineer to determine the Load Bearing Capability and Wind Speed Survivability of such an Installation. Guying is an absolute must, but remember that guying will simply increase the down pressure onto the Base support, which in this case, is your Roof!
