AP-85025

The AP-85025 is a high-capacity, strategic directional antenna designed for long-range terrestrial point-to-point links in the 700–990 MHz UHF band. Featuring a massive 3-meter (10 feet) diameter grid parabolic reflector, it provides an exceptional 25.5 dBi gain, making it a premier choice for high-bandwidth analogue and digital backhaul in both tactical and fixed-station environments.

High-Gain Precision

The AP-85025 is engineered for maximum signal density, delivering a razor-sharp 8-degree beam-width that concentrates RF energy with clinical accuracy. This narrow aperture, combined with a 36 dB Front-to-Back ratio, ensures elite interference rejection from neighboring signal sources. The antenna utilizes a high-conductivity brass dipole feed with an Air-Cored transmission line, minimizing internal insertion loss to maintain a high signal-to-noise ratio (SNR) over extreme distances.

Industrial-Grade Structural Integrity

Built to survive in the most punishing theaters, the 3-meter reflector is constructed from 6063T6 architectural-grade anodized aluminum alloy. The grid architecture is a critical efficiency feature; the 16 mm grid members allow wind to pass through the reflector, significantly reducing the "sail effect" and torque on the tower compared to solid dishes. This results in a high wind rating of 195 Km/Hr. The entire array is finished with an epoxy-based anti-corrosive powder coating in military olive green for maximum defense against salt fog and UV degradation.

Operational and Tactical Efficiency

Despite its strategic size, the AP-85025 is designed for practical field use, requiring only two operators for installation. It features a quick fastener system for the central feed horn and an integrated elevation tracking mechanism providing +/- 5 degrees of fine adjustment for peak link optimization. To ensure mechanical stability in high-wind zones, the antenna is supplied with two side struts for extra rigidity. Electrically, the antenna operates at direct D.C. ground, shielding connected radio equipment from lightning transients and atmospheric static.
