The AP-145022 is a professional-grade directional antenna designed for high-performance terrestrial point-to-point communication in the 1427-1535 MHz band. Featuring a 1.2-meter (4-foot) diameter grid parabolic reflector, this model offers a strategic balance of gain (22 dBi) and tactical portability, making it an ideal choice for both rapid field deployments and permanent fixed-station radio links.
Performance, Durability, and Efficiency
Precision Directional Performance
The AP-145022 provides a focused 12-degree beam-width, ensuring that RF energy is concentrated toward the target receiver to maximize link stability and range. With a 28 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-145022 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 just 18 Kgs, the AP-145022 is highly portable and manageable for tower-top installations. 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.
