| AP-35018 | Grid Parabolic Antenna 3.0 Meters | 330–400MHz. | 18 dBi. |  |  |  |
The AP-35018 is a professional-grade UHF terrestrial microwave antenna engineered for the 330–400 MHz band. Featuring a massive 3.0-meter (10-foot) diameter grid parabolic reflector, it delivers an impressive 18 dBi gain. This antenna is specifically optimized for high-capacity digital backhaul and tactical communication links, offering a superior balance of signal density and structural resilience for fixed-site and rapid-deployment infrastructure.
Strategic UHF Performance
The AP-35018 provides exceptional directional accuracy with a focused 20-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 38 dB Front-to-Back ratio and 34 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 3-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, drastically reducing wind load compared to solid dishes and achieving a wind rating of 190 Km/Hr. To ensure the antenna remains stable and the beam stays on-target during severe weather, it is supplied with two side struts for enhanced rigidity.
Operational and Tactical Efficiency
Despite its significant strategic scale, the AP-35018 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 primary feed horn features a quick fastener system for rapid assembly, and the radiating elements are manufactured from high-quality brass with an Air-Cored transmission line for maximum electrical conductivity. For electrical safety, the antenna operates at direct D.C. ground, providing an immutable discharge path for lightning.

Design Features: The AP-35018 grid parabolic antenna consists of full Parabolic reflector having a diameter of 3 Meters for use in all tactical and fixed station applications for terrestrial point to point analogue and digital communication radio link. The antenna covers 40 MHz bandwidth, operates in linear polarization and requires two operators for installation. The antenna dipole feed uses an Air-Cored transmission line. The mounting arrangement of Grid Parabolic Antenna permits to change the polarization from horizontal to vertical and vice-versa by mounting hardware fitted at rear end of the antenna. The antenna is supplied with +/-10 degrees elevation tracking mechanism. The grid parabolic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise.
