VMP FRM-125 Powder Coat Non-Pen Antenna Roof Mount 1.25 OD x 60 in. Mast

Height and Antenna Loading capability are dependent upon ballast weight to counter the tip-over moment of the Windspeed rating desired. In addition to the Windspeed Loading Data found under the "Specification" tab (if Available), You need to Consult an Engineer to determine the Building Code Requirements and Load Bearing Capacity of the roof structure where you will be installing this mount. It is Important to choose a Mount and Mounting Location with a Picture of the Finished Installation in Mind. Be Sure to First select a location that lends itself to applying a Load without Compromising the Integrity of the Material you place the mount on top of; i.e. roof membrane, covering, decorative cover, etc., or the Structural Members beneath. Next consider the Location over a Lifetime of Adjustments, does it lend itself to modifications in Height or Direction? Larger Antennas increase the surface area presented to air movement and thus, Wind-load does increase. As the height of the mast increases from Its last attached point on the structure, the torque applied in cantilever towards the tip-over moment also increases with Antenna off-center Weight and Wind-Load EPA (Effective Projected Area), requiring a more substantive Downward Force and/or Load Dissipation; i.e. supplemental Down-guys may be required as to keep ballast weight within Load-bearing capacity. Keep the Distance Minimal from the Antenna to the Equipment you feed, as to minimize loss and the need for Amplification.
A Retention Tether SCK150 (Safety Cable Kit) is required for Commercial Installations to mitigate Loss and Damage to Property, Further, the FRM-PAD or FRM-MAT is recommended for all installations to prevent slippage, distribute weight more evenly and prevent damage to the roof surface
