A 3-Sector T-Arm Monopole Antenna Mount is a specialized structure designed to support three directional antennas spaced 120° apart on a single monopole. This configuration maximizes cellular network coverage and capacity by dividing a 360° area into three independent 120° sectors, each served by its own antenna/RF system.
Monopole Structure
Material: Galvanized steel or aluminum alloy.
Height: 30–200 ft (9–60m), tailored for urban/suburban coverage.
Foundation: Reinforced concrete base (5–15m depth) for wind/seismic stability.
T-Arm Assembly
Configuration: Three horizontal arms welded/bolted at 120° intervals.
Arm Length: 6–20 ft (1.8–6m), depending on antenna size and wind load.
Material: Steel tubing (e.g., ASTM A500) with corrosion-resistant coating.
Antenna Mounts
Adjustability:
Azimuth: ±15° fine-tuning for sector alignment.
Downtilt: Mechanical (0°–10°) or electrical (0°–15°) for coverage shaping.
Hardware: U-bolts, clamping brackets (e.g., Rohn SS25H), and torque limiters.
Ancillary Attachments
RRUs (Remote Radio Units): Mounted behind antennas to minimize feeder loss.
Cable Management: Ladder racks, drip loops, and grounding kits (IEEE 80 compliant).
Auxiliary Mounts: Microwave backhaul dishes, small cells, or IoT sensors.
