AP-145019

The AP-145019 is a professional-grade directional antenna designed for high-performance terrestrial point-to-point communication in the 1300–1600 MHz band. Featuring a compact 0.9-meter (3-foot) diameter grid parabolic reflector, this model offers a strategic balance of high directivity (19 dBi gain) and exceptional tactical portability, making it an ideal choice for rapid field deployments and fixed-station radio links where space or weight is a constraint.

Precision Directional Performance

The AP-145019 provides a focused 16-degree beam-width, ensuring that RF energy is concentrated toward the target receiver to maximize link stability. With a 23 dB Front-to-Back ratio, it effectively minimizes interference from 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-145019 is built to withstand extreme mechanical stress while remaining ultra-lightweight. 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 10 Kgs, the AP-145019 is highly portable and manageable for single-operator transport, though two are recommended for rapid mast 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.
