1-Technical Description & Features Breakdown VHF Fiberglass Omni Antenna
The VHF Fiberglass Omni Antenna is a heavy-duty, high-reliability station antenna precision-engineered for wide-area coverage across the 134 MHz to 174 MHz professional mobile radio (PMR) band. Housed inside a rugged, weather-sealed white fiberglass radome, this low-profile vertical antenna is designed to withstand extreme wind loads, severe icing, and UV degradation. It is a critical asset for municipal public safety networks, marine communications, emergency dispatch operations, and utility telemetry arrays requiring continuous, 360-degree signal propagation.
- High-Efficiency Radiation: Delivers a stable 3.2 dBi gain paired with a concentrated 66° vertical beamwidth, maximizing ground-level cell-edge footprint extension while minimizing skyward RF leakage.
- Heavy-Duty Power Handling: Safely supports continuous transmitter loads up to 100 Watts, providing deep building penetration and crisp voice/data links.
- Low-Loss N-Female Interface: Features a gas-tight, heavy-duty N-Female connector recess at the antenna base for seamless, weatherproof low-loss cable runs.
- Rugged Base Station Mounting: Tailored for rock-solid mast clamping across standard Φ40mm to φ50mm poles, ensuring steady vertical polarization geometry under high vibrations.
2-Particular Specification and Features VHF Fiberglass Omni Antenna
Electrical & Mechanical Subsections VHF Fiberglass Omni Antenna
- Premium Fiberglass Radome: Built with an ultra-durable, all-white protective housing that minimizes signal attenuation while shielding copper elements from wind, rain, and ice.
- Stable Omnidirectional H-Plane: Delivers uniform 360-degree horizontal signal distribution, eliminating dead zones around the transmission site.
- Low VSWR Profile: Maintains a highly efficient impedance match (VSWR ≤1.5) across the entire operational VHF spectrum window.
