GROUND PLANE ANTENNA 0DB GAIN 136-174 Mhz

The Ground Plane Antenna with 0 dB gain, operating in the 136–174 MHz VHF band, is a reliable omnidirectional antenna designed for stable, short-to-medium range communication. Engineered for consistent performance, it is widely used in VHF land mobile radio systems, base stations, repeaters, and monitoring applications where uniform signal coverage is essential.

This antenna features a quarter-wave vertical radiator combined with radial ground elements, forming an efficient ground plane that provides a balanced radiation pattern. With 0 dB gain, the antenna radiates energy evenly in all horizontal directions, making it ideal for applications that require equal coverage around the installation point rather than focused or directional gain.

Constructed using high-quality conductive materials such as aluminum or brass, the antenna offers low loss, high efficiency, and excellent impedance matching across the entire 136–174 MHz frequency range. The rugged mechanical design ensures long-term outdoor durability, with resistance to corrosion, wind, rain, and harsh environmental conditions.

The antenna is typically supplied with a standard mounting arrangement for mast or pole installation and is compatible with commonly used RF connectors such as N-Type or SO-239, allowing easy integration with VHF radios and coaxial cables. Its simple structure makes installation and maintenance straightforward, even in remote or elevated locations.
