The Ground Plane Antenna operating in the 450–520 MHz frequency range with 3 dBi gain is designed to deliver reliable, uniform signal coverage for UHF wireless communication systems. Built on a classic quarter-wave monopole configuration with a precisely engineered ground plane, this antenna provides stable impedance, low VSWR, and consistent omnidirectional radiation performance.
Covering a wide UHF bandwidth, the antenna is suitable for applications such as PMR, TETRA, paging systems, telemetry, SCADA, base stations, and other professional radio communication networks. The 3 dBi gain offers an effective balance between coverage and signal strength, improving communication range while maintaining a broad radiation pattern in the horizontal plane.
The antenna features a vertically polarized radiation pattern with 360-degree omnidirectional coverage, making it ideal for fixed installations where uniform signal distribution is required. Its robust mechanical design ensures dependable performance in both indoor and outdoor environments. Corrosion-resistant materials and durable construction allow reliable operation under varying weather conditions.
Easy to install on masts, poles, or flat mounting surfaces, the ground plane antenna is compatible with standard RF connectors and commonly used coaxial cables. With its stable electrical characteristics, efficient radiation efficiency, and long service life, this 450–520 MHz 3 dBi Ground Plane Antenna is a dependable solution for professional and industrial UHF communication applications.
