| AP-45015 | Grid Parabolic Antenna 1.8 Meters | 406-512MHz. | 15 dBi. |  |  |  |
The AP-45015 is a professional-grade UHF terrestrial microwave antenna engineered for the 406–512 MHz band. Featuring a 1.8-meter (6-foot) diameter grid parabolic reflector, it delivers a strategic 15.5 dBi gain. This antenna is optimized for high-capacity digital backhaul and tactical communication links, offering a superior balance of signal focus and structural resilience for fixed-site and rapid-deployment infrastructure.
Strategic UHF Performance
The AP-45015 provides exceptional directional accuracy with a focused 26-degree beam-width. This aperture concentrates RF energy with precision, maximizing link distance while effectively isolating the signal from adjacent interference. Performance is further stabilized by a 32 dB Front-to-Back ratio and 28 dB cross-polarization discrimination, ensuring the superior signal-to-noise ratio (SNR) required for sophisticated digital data transmission across its 40 MHz bandwidth.
Industrial-Grade Structural Hardening
Constructed from 6063T6 architectural-grade anodized aluminum alloy, the 1.8-meter reflector is built to survive punishing environmental theaters. The grid architecture is a critical efficiency feature; the open-frame design allows wind to pass through the reflector, drastically reducing wind load compared to solid dishes and achieving a high wind rating of 200 Km/Hr. For defense against coastal and industrial pollutants, the entire assembly is finished with an epoxy-based anti-corrosive powder coating in tactical olive green.
Operational and Tactical Efficiency
At a gross weight of 36 Kgs, the AP-45015 is manageable for field deployment and requires two operators for installation. It features a quick fastener system for the primary feed and an integrated +/- 5 degrees elevation tracking mechanism for fine-tuning signal alignment. The mounting hardware permits a near-instant switch between Horizontal and Vertical polarization. Electrically, the antenna operates at direct D.C. ground, providing an immutable discharge path for lightning and immunity to atmospheric noise.
