COLLINEAR ANTENNA 136-174 Mhz

The 136–174 MHz 2 dBi Collinear Antenna is a high-quality VHF omni-directional antenna designed to deliver stable, uniform signal coverage for professional and commercial radio communication systems. Engineered using a collinear radiating structure, this antenna provides enhanced horizontal radiation performance compared to a standard dipole, making it ideal for base stations, repeaters, and fixed installations operating in the VHF band.

Operating efficiently across the 136–174 MHz frequency range, the antenna supports applications such as land mobile radio (LMR), public safety networks, utilities, railways, marine communication, and amateur radio (VHF). The 2 dBi gain offers a balanced improvement in signal strength while maintaining wide area coverage, ensuring reliable communication in both urban and rural environments.

The antenna features a rugged, weather-resistant construction, typically enclosed in a durable fiberglass or UV-stabilized radome that protects internal elements from harsh environmental conditions such as rain, dust, wind, and prolonged sun exposure. Its corrosion-resistant hardware ensures long service life, even in outdoor installations.

With an omni-directional radiation pattern, the antenna provides consistent 360-degree coverage, making it suitable for mounting on towers, masts, rooftops, or poles. The design supports low VSWR across the operating band, enabling efficient power transfer, reduced signal loss, and improved overall system performance.
