AP-35020

The AP-35020 is a strategic-grade UHF terrestrial microwave antenna designed for the 300–406 MHz (specifically optimized for the 330–400 MHz segment). Featuring a massive 4.0-meter (13.2-foot) grid parabolic reflector, it delivers an elite 20 dBi gain. This antenna is engineered for maximum-distance point-to-point links and high-capacity digital backhaul where extreme signal stability and structural resilience are mission-critical.

Strategic UHF Performance

The AP-35020 represents the pinnacle of UHF directional technology, offering a focused 15-degree beam-width. This narrow aperture concentrates RF energy with precision, maximizing link distance for "backbone" communication while effectively rejecting interference from adjacent signal sources. Performance is further stabilized by an exceptional 40 dB Front-to-Back ratio and 36 dB cross-polarization discrimination, ensuring the high 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 4.0-meter reflector is built to survive punishing environmental theaters. The grid architecture is a critical efficiency feature; the 16 mm (5/8 inch) grid members allow wind to pass through the reflector, significantly reducing the "sail effect" and torque on the tower compared to solid dishes. This enables a wind rating of 190 Km/Hr. To maintain structural integrity and parabolic precision, the antenna is supplied with two side struts to provide extra rigidity to the 200 Kg assembly.

Operational and Tactical Efficiency

Despite its strategic scale, the AP-35020 is designed for professional field optimization. It includes an elevation tracking mechanism allowing for fine +/- 5 degree adjustments, essential for "dialing in" peak signal strength on long-distance hops. The radiating elements and dipole feed are manufactured from high-quality brass for maximum electrical conductivity. For electrical safety, the antenna operates at direct D.C. ground, providing an immutable discharge path for lightning and atmospheric static to protect ground-station equipment.
