3S-FRM-HDW Non-Pen Roof Mount FRM Frame for up to 2.25 inch OD Antenna Mast
3 Star Inc.
Made in the USA!
Ideal for Light Off-Air TV, Satellite Dish and Wireless Internet Antenna mounting, is constructed of pre-galvanized steel, uses 8 standard concrete blocks to anchor, 35.5" x 35.5" base. The Assembly comes with a GR-3 Universal Clamp that allows you to insert masts from 1.5 to 2.25 inch OD and tighten set screws to secure. The mast You supply will need to be drilled to accept a 1/4-20 carriage bolt that secures the mast bottom to the Frame Base. This Order is for the Base Frame Only (No Mast, Cinder Blocks or Mat Supplied). Bring your own Mast and drill to fit!
This Frame can support Telescoping and other Masts 10 ft. and Higher, but not in a Frame-Only self-supporting configuration. You will need to integrate Down Guys for additional Wind-load resistance.
Light Duty Antennas on 1.50" OD Mast of 10 ft. may be guyed back onto the Frame itself, whereas all other diameter masts at this height or higher will require Down-Guy Tie-Down points (anchoring) at distances farther out, away from the Base.

*Redesign Difference from Legacy "RT" to New "RTL" Towers*
The "RT" Series Tower Sections had cross bracing segments that spanned from one Tower Section to the next.
The "RTL" Series Towers Sections feature cross bracing that starts,stops and is contained within the same Tower section; making it easier to assemble a complete tower section on the ground for lifting and easier attachment/fitting onto the next Tower Section during erection.
