The Ground Plane Antenna with 6 dB gain for the 136–174 MHz VHF band is a high-performance omnidirectional antenna designed to deliver extended range, improved signal clarity, and reliable communication in demanding environments. Engineered for professional VHF applications, this antenna provides enhanced horizontal radiation, making it ideal for base stations, repeaters, and fixed communication systems.
Operating across the full 136–174 MHz frequency range, the antenna covers land mobile radio, marine, aviation ground support, public safety, and commercial VHF services. The 6 dB gain is achieved through an optimized radiator and ground-plane element design that focuses RF energy toward the horizon, resulting in stronger signals over longer distances compared to standard 0 dB or 3 dB antennas.
The antenna features a robust ground plane structure with precisely tuned radial elements that ensure stable impedance, low VSWR, and consistent performance across the band. Its omnidirectional radiation pattern provides uniform 360-degree coverage, making it suitable for wide-area communication without the need for antenna alignment.
Constructed using high-quality corrosion-resistant materials, the antenna is built to withstand harsh outdoor conditions, including UV exposure, rain, wind, and temperature variations. The durable mechanical design ensures long service life with minimal maintenance, even in continuous operation.
This 6 dB ground plane antenna is easy to install on masts, towers, or rooftop mounts and is compatible with standard VHF coaxial cables and connectors. It is an excellent choice for base stations, control rooms, repeater sites, industrial facilities, and infrastructure communication systems requiring reliable VHF coverage and improved range.
