ROHN FRM238 Non-Penetrating Roof Antenna Mount 2.375" OD x 30 inch Mast
ROHN
Made in the USA!
This roof mount is able to support various Antenna EPA's depending on wind and Ballast load (see details). The base of the roof mount is 3’ square with a 16" tray to fit concrete blocks, typically used as ballast for placement of various TV, Radio, Microwave, WiFi and Wireless Internet Antennas. The base mount is 16 gauge Pre-Galvanized and the mast tube is thick-walled galvanized steel for corrosion protection and go together quickly.
Mast Dimensions - 2.375" 14 GA Pipe (2-3/8 O.D.) x 30”
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

Keystone Jack Module Inserts
A Keystone module is an industry standard type of wall jack used in residential and business environments. The system consists of a modular face plate to which jacks are mounted. Flush mount Keystone Wallplates will fulfill the most complicated station installation requirements through a wide selection of snap-in modules. A variety of jacks and connectors will fill the wall plate openings to meet your specific requirements of voice, data, audio, video, fiber optic, etc. The inserts are a snap to install and remove, giving you a highly adaptable system.
A keystone jack module is a standardized snap-in package for mounting a variety of low-voltage electrical jacks such as TV, Phone, LAN, Data, BNC, RCA or optical connectors into a keystone wall plate, surface-mount box, or a patch panel. Keystone modules have a commonly popular standardized rectangular face of 14.5mm wide by 16.0mm high and are held in place with a flexible tab. This allows them to be snapped into or out of a mounting plate with correspondingly-sized rectangular holes, called ports. All keystones, regardless of the type of jack they carry, are interchangeable and replaceable. This is what makes Keystone a popular choice in today's installations at Home or Office. Some keystones use a pass-though type connector, where there is a jack on both the front face as well as the rear side. Others only have a jack on the front and employ a different means for hard-wiring signal cables in the rear, such as a mini 110, insulation-displacement connector, crimp or solder connection.
