Description
Heavy-Duty Aluminum Antenna Wall & Mast Mounting Kit (Pair of Brackets)
Professional-grade extruded aluminum dual-bracket mounting kit with stainless steel U-bolts for fiberglass base station antennas up to 1.4" OD on masts up to 2.5" OD.
The Purchase Radios FM2 (formerly manufactured and cataloged under TE Connectivity / Laird part FM2, Tessco SKU 69293) is a commercial-grade, heavy-duty antenna mounting bracket kit engineered to deliver rock-solid physical stabilization for base station antennas. Designed for public safety dispatch centers, utility substations, coastal AIS marine monitoring sites, commercial LMR repeater sites, and fixed wireless networks, this dual-bracket system secures omnidirectional antennas against extreme weather and mechanical vibration. Sourced directly from our verified inventory of Two-Way Radio Antennas, the FM2 kit provides the rugged physical foundation needed to maintain antenna alignment and transmission reliability.
Constructed from heavy-duty extruded marine-grade aluminum paired with corrosion-resistant 18-8 stainless-steel U-bolts and locking hardware, the Purchase Radios FM2 is built to endure harsh outdoor exposure. Tested against atmospheric salt spray and galvanic corrosion in compliance with ASTM Standards (ASTM B117) and built to withstand severe wind buffeting tested under DoD Standards (MIL-STD-810H), this bracket kit provides two-point vertical clamping that prevents antenna rotation and mast slippage during gale-force winds. Meeting structural tower support requirements under TIA Standards (ANSI/TIA-222) and ergonomic tower-climbing safety practices under OSHA Standards, the FM2 clamps antennas up to 1.4 inches (35.6 mm) in diameter onto mast poles ranging from 1.25 to 2.5 inches (31.8 to 63.5 mm) in diameter. Integrated rear mounting slots also allow direct anchoring to concrete walls, building parapets, and equipment shelters.
Key Features & Benefits
-
Matched Dual-Bracket Pair: Includes two heavy-duty extruded aluminum brackets to provide two-point vertical clamping that prevents antenna twisting and pivoting.
-
Heavy-Duty Mast Clamping: Accommodates vertical masts and tower pipe legs from 1.25 inches to 2.5 inches outside diameter (OD).
-
Broad Antenna Compatibility: Sized to clamp standard fiberglass base station antennas and collinear poles with outside diameters up to 1.4 inches (35.6 mm).
-
Multi-Surface Installation Flexibility: Mounts seamlessly to tubular mast pipes or directly to flat building walls, parapets, and equipment shelter bulkheads.
-
Corrosion-Resistant Hardware: Premium extruded aluminum brackets paired with stainless steel U-bolts and lock washers resist coastal salt air and industrial smog.
-
High Wind-Load Stability: Distributes mechanical stress across the antenna base sleeve, preventing fiberglass fracture during severe storm events.

Frequently Asked Questions
Is this the exact same mounting kit previously sold under Laird and TE Connectivity?
Yes. The Purchase Radios FM2 is identical in tooling, physical dimensions, extruded aluminum alloy, and hardware specifications to the legacy TE Connectivity and Laird Technologies FM2 bracket kit (Tessco SKU 69293).
What size antennas can be installed using the FM2 mounting kit?
The FM2 bracket kit is engineered to clamp base station antennas with an outside diameter (OD) of up to 1.4 inches (35.56 mm). This covers the entire Laird / Antenex FG series fiberglass antenna line and similar commercial VHF, UHF, and 800/900 MHz omnidirectional antennas.
What size mast pole does this bracket clamp onto?
The included stainless steel U-bolts and saddle brackets clamp onto standard schedule 40 pipes, tubing, and antenna masts with an outside diameter between 1.25 inches (31.8 mm) and 2.5 inches (63.5 mm).
Can I mount this bracket directly to a flat building wall?
Yes. Each bracket features pre-drilled flat-flange mounting holes. To wall-mount, discard the round U-bolts and secure the brackets directly to concrete, masonry, wood, or steel surfaces using appropriate anchor fasteners (anchors sold separately).
