GROUND PLANE ANTENNA 3DB GAIN 136-174 Mhz

The 136–174 MHz 3 dB Gain Ground Plane Antenna is a high-performance VHF antenna designed to deliver reliable omnidirectional coverage for land mobile, marine, aviation support, and amateur radio applications. Engineered for durability and consistent signal performance, this antenna is ideal for base stations, repeater sites, and fixed installations where stable communication across the entire VHF band is essential.

Operating across the 136–174 MHz VHF frequency range, the antenna provides a 3 dB gain, offering improved signal strength and extended communication range compared to standard 0 dB ground plane antennas. Its radiation pattern is optimized for low-angle transmission and reception, ensuring excellent coverage over wide areas, especially in flat or semi-urban terrain.

The antenna features a ground plane design with multiple radials, which enhances impedance matching, reduces signal loss, and ensures consistent performance across the full operating band. The vertical polarization makes it fully compatible with most VHF radio systems used in commercial, public safety, and amateur radio networks.

Constructed using high-quality corrosion-resistant materials, the antenna is built to withstand harsh outdoor environments, including extreme temperatures, rain, wind, and UV exposure. Its rugged mechanical design ensures long service life with minimal maintenance, making it suitable for continuous outdoor operation.

Installation is simple and flexible, with compatibility for standard mounting brackets and masts. The antenna supports commonly used RF connectors, allowing easy integration with a wide range of VHF transceivers and coaxial feed lines.
