The AP-180027 is a professional-grade directional antenna designed for high-performance terrestrial point-to-point communication in the 1700–2000 MHz band. Featuring a 1.85-meter (6-foot) diameter grid parabolic reflector, this antenna offers a strategic balance of high gain (27 dBi) and structural resilience, making it an ideal choice for both tactical field deployments and permanent fixed-station radio links.
Precision Directional Performance
The AP-180027 provides a focused 6.5-degree beam-width, ensuring that RF energy is concentrated toward the target receiver to maximize link stability and range. With a 30 dB Front-to-Back ratio, it effectively rejects interference from neighboring towers or rearward noise sources. The antenna utilizes high-conductivity brass radiating elements and a precision dipole feed with an Air-Cored transmission line to maintain clear analogue or digital transmission across its 150 MHz bandwidth.
Tactical Mechanical Hardening
Constructed from 6063T6 architectural-grade anodized aluminum alloy, the AP-180027 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 an exceptional wind rating of 200 Km/Hr. The entire assembly is finished with an epoxy-based anti-corrosive powder coating in military olive green, providing a defensive shield against salt fog and UV degradation.
Operational and Logistical Efficiency
At a gross weight of 35 Kgs, the AP-180027 is manageable for tower-top installations and requires only two operators for installation. It features an integrated +/- 5 degrees elevation tracking mechanism for fine-tuning signal alignment after mounting. For mission versatility, the mounting hardware at the rear permits a quick 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-180027 grid parabolic antenna consists of full Parabolic reflector having a diameter of 1.8 Meters for use in all tactical and fixed station applications for terrestrial point to point analogue and digital communication radio link. The antenna covers 150 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.
