| AG-450 | UHF Base Station Ground Plane Antenna | 406-512MHz | Unity |  |  |  |
The AG-450 is a professional-grade, military-hardened Omni-Directional Ground Plane Antenna precision-engineered for the 406–512 MHz UHF spectrum. Constructed from high-class chrome-plated brass, this rugged all-weather model is designed for elite base station performance in military, public safety, and industrial trunking networks. With a focus on signal purity and high-power stability, the AG-450 provides Unity Gain (2.15 dBi) and an impressive 500-Watt power handling capacity, making it a primary choice for high-intensity UHF broadcasting and spectrum monitoring.
Strategic Construction & Signal Purity
Hardened materials for zero-maintenance operational life. The AG-450 utilizes an all-brass radiating architecture, which is fundamental for preventing the formation of "Signal Cells." This design choice eliminates internal inter-modulation (IM) and ensures signal fidelity, even when operating high-power transmitters. The radiating core is finished with high-class chrome plating, providing an elite layer of protection against corrosive atmospheric gases, salt spray, and UV radiation. All mounting hardware and fasteners are fabricated from marine-grade stainless steel.
Operational Efficiency
True omni-directional 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 narrower-beam antennas. For maximum field survivability, the N-Female termination and feed cable are completely enclosed within the mounting pipe, shielding critical RF connections from moisture, ice, and mechanical strain.
Detailed Technical Features
