AG3-850

The AG3-850 is a professional-grade Omnidirectional Ground Plane Antenna specifically engineered for the high-frequency 700 – 990 MHz band. This spectrum includes critical LTE, GSM, and specialized military communication frequencies. Constructed from high-class chrome-plated brass, this antenna provides a high-efficiency solution for base station infrastructure where wideband coverage and mechanical survivability are mandatory. With a stable 3 dBi gain and a massive 500-Watt power handling capacity, the AG3-850 is a primary choice for high-intensity signal broadcasting and cellular monitoring.

Strategic Construction & Signal Purity

Hardened materials for zero-maintenance operational life. The AG3-850 features an all-brass radiating architecture, which is fundamental for preventing the formation of "Signal Cells." This design choice eliminates internal inter-modulation (IM), ensuring the antenna maintains absolute signal fidelity even when operating high-power transmitters. The radiating core is finished with high-class chrome plating, providing an elite defense against corrosive atmospheric gases, UV radiation, and industrial pollutants. All mounting hardware is fabricated from marine-grade stainless steel.

Operational Efficiency

True omnidirectional dominance with superior "Null Fill." The antenna delivers a stable 360-degree horizontal radiation pattern with a 72-degree vertical beamwidth. This wide elevation aperture provides excellent "null fill," ensuring the localized area is saturated with signal and effectively eliminating the communication "dead zones" common with higher-gain, narrower-beam antennas. For maximum field survivability, the N-Female termination and feed cable are completely enclosed within the mounting pipe, shielding the critical RF connections from moisture, ice, and mechanical strain.
