AG3-350

The AG3-350 is a professional-grade, high-gain Omnidirectional Ground Plane Antenna engineered for the 300–400 MHz UHF spectrum. Constructed from high-quality brass with a specialized Nickel Chromium plating, this rugged all-weather model is designed for elite base station performance in military and industrial applications. Delivering a stable 3 dBi gain and a robust 500-Watt power handling capacity, the AG3-350 ensures reliable 360-degree signal saturation across a 20 MHz bandwidth without requiring field tuning.

Hardened Construction & Strategic Finish

Enhanced durability for persistent performance in severe theaters. The AG3-350 utilizes an all-brass radiating architecture, which is fundamental for preventing "Signal Cells." This design eliminates internal inter-modulation (IM) and ensures signal purity, even when operating high-power transmitters. The addition of a Nickel Chromium plating provides an extra layer of defense against extreme environmental conditions, such as high-salinity coastal air or industrial pollutants. All mounting hardware and fasteners are fabricated from marine-grade stainless steel for total corrosion immunity.

Operational Efficiency

True omnidirectional dominance with superior "Null Fill." The antenna features a 78-degree vertical beamwidth, providing an exceptionally wide elevation aperture. This design ensures excellent "null fill," effectively saturating the local area with a consistent signal and eliminating the communication "dead zones" common in narrower-beam antennas. For maximum field survivability, the N-Female termination and feed cable are completely enclosed within the mounting pipe, shielding the most vulnerable electrical connections from moisture, ice, and mechanical strain.
