| AP-85017 | Grid Parabolic Antenna 1.2 Meters | 700–990MHz | 17 dBi. |  |  |  |
The AP-85017 is a professional-grade directional antenna designed for high-performance terrestrial point-to-point communication in the 700–990 MHz UHF band. Featuring a 1.2-meter (4 feet) diameter grid parabolic reflector, this antenna offers a strategic balance of high gain (17 dBi) and low wind loading, making it an ideal choice for tactical field deployments and permanent fixed-station radio links.
Precision Directional Performance
The AP-85017 provides a focused 19-degree beam-width, ensuring that radio signals are concentrated toward the target receiver for maximum link stability. With a 28 dB Front-to-Back ratio, it effectively rejects interference from neighboring towers or rearward noise sources. The antenna utilizes a high-conductivity brass dipole feed with an Air-Cored transmission line, minimizing signal loss and ensuring clear analogue or digital transmission across an 80 MHz bandwidth.
Tactical Mechanical Hardening
Constructed from 6063T6 architectural-grade anodized aluminum alloy, the AP-85017 is built to withstand extreme mechanical stress. The grid architecture is a key efficiency feature, allowing wind to pass through the reflector and reducing drag significantly compared to solid dishes. This results in a high wind rating of 200 Km/Hr. The entire structure is finished with an epoxy-based anti-corrosive powder coating in military olive green, providing a defensive shield against salt fog, acid rain, and UV degradation.
Operational and Logistical Efficiency
At just 18 Kgs, the AP-85017 is highly portable and can be installed by two operators. It features a quick fastener system for the primary feed and an integrated +/- 5 degrees elevation tracking mechanism for fine-tuning signal alignment after mounting. For mission versatility, the hardware at the rear permits a near-instant switch between Horizontal and Vertical polarization. Electrically, the antenna operates at direct D.C. ground, shielding connected radio equipment from lightning-induced transients and atmospheric noise.

Design Features: The AP-85017 grid parabolic antenna consists of full Parabolic reflector having a diameter of 1.2 Meters for use in all tactical and fixed station applications for terrestrial point to point analogue and digital communication radio link. The antenna covers 80 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.
