COLLINEAR ANTENNA 136-174 Mhz

The 136–174 MHz 3 dBi Collinear Antenna is a high-performance VHF omni-directional antenna designed to deliver reliable and extended coverage for professional radio communication systems. Operating efficiently across the VHF band, it is ideal for applications such as two-way radios, land mobile radio (LMR) networks, public safety, utilities, transportation, marine, and amateur radio communications.

This antenna uses a collinear radiating element design, which stacks multiple antenna elements in phase to achieve higher gain and a flatter radiation pattern. The result is improved signal strength and enhanced communication range compared to standard 0 dBi antennas, while maintaining uniform 360-degree coverage in the horizontal plane. The 3 dBi gain makes it especially suitable for base stations and fixed installations where consistent area coverage is required.

Constructed with high-quality conductive elements and enclosed in a durable, weather-resistant radome, the antenna is engineered for long-term outdoor use. It performs reliably in harsh environmental conditions, including high temperatures, humidity, wind, and rain. The robust mechanical design ensures stable performance with minimal maintenance.

The antenna is designed for low VSWR and high efficiency across the entire 136–174 MHz frequency range, ensuring optimal power transfer and reduced signal loss. It supports both analog and digital VHF communication systems and is compatible with a wide range of radios and transmitters.

Easy to install, the collinear antenna can be mounted on poles, masts, or towers and is suitable for rooftops, communication sites, and remote installations. Its clean radiation pattern and dependable performance make it a cost-effective solution for improving VHF communication coverage.
