COLLINEAR ANTENNA 136-174 Mhz

The 136–174 MHz 6 dBi Collinear Antenna is a high-performance, vertically polarized omni-directional antenna engineered for VHF communication systems that require extended range, stable coverage, and reliable signal quality. Designed using a collinear radiator structure, this antenna stacks multiple radiating elements in phase to achieve higher gain while maintaining a uniform 360-degree horizontal radiation pattern.

Operating efficiently across the 136–174 MHz VHF band, the antenna is ideal for land mobile radio (LMR), public safety networks, amateur radio, marine and aviation support systems, repeaters, and base station installations. The 6 dBi gain significantly improves signal reach and clarity, making it well suited for both urban and wide-area outdoor deployments.

The antenna features a robust, weather-resistant construction, typically enclosed in a high-strength fiberglass or UV-stabilized radome, ensuring long service life in harsh environmental conditions such as rain, heat, wind, and dust. Its low-loss internal phasing network ensures consistent performance with minimal signal degradation, while the optimized impedance provides low VSWR across the operating band.

With vertical polarization, the antenna ensures maximum compatibility with standard VHF mobile and handheld radios. The omni-directional radiation pattern delivers consistent coverage in all directions, making it an excellent choice for fixed installations where uniform area coverage is required. The antenna is suitable for mast, tower, or pole mounting and is easy to install and maintain.
