SC-243-318

The SC-243-318 is a compact, high-performance SATCOM Collinear Antenna specifically engineered for the military UHF aviation and satellite communication bands between 243–318 MHz. Designed for maximum tactical flexibility, this ruggedized aperture is optimized for man-pack, vehicle-mount, and fixed-station applications. Featuring vertically stacked brass radiating elements and a specialized coaxial stub feed, the SC-243-318 provides consistent omni-directional coverage and 200W power handling in a lightweight, low-profile form factor.

Design: Tactical Mobility & SATCOM Interoperability

The SC-243-318 is built for rapid-response units and mobile command platforms that require reliable SATCOM links without the bulk of traditional arrays.

• Targeted 243–318 MHz Bandwidth: Precision-tuned for military UHF SATCOM and aero bands, enabling seamless coordination between ground teams, tactical vehicles, and airborne assets.
• Compact Tactical Profile: At only 330 mm (13 inches) in length and weighing just 500 grams, it is one of the most portable apertures in its class, making it ideal for integration onto soldier-worn man-packs or low-profile vehicle roof mounts.
• Collinear Gain Efficiency: By stacking high-grade brass radiating elements vertically and feeding them in-phase, the antenna delivers a stable 2 dBi gain with a wide 78-degree vertical beamwidth, ensuring reliable links even while the vehicle or operator is in motion.
• Plug-and-Play Performance: Engineered with a specialized coaxial stub and spark gap technique to ensure a smooth VSWR (2:1) across the entire band without requiring any field tuning or adjustments.

Construction: Ruggedized & Mission-Ready

Built to survive the rigors of combat and extreme environmental exposure.

• ABS Protection: The radiating elements are fully enclosed in a high-strength ABS radome (32 mm diameter). This material offers excellent RF transparency while providing the mechanical robustness needed to withstand impacts and vibrations.
• High-Grade Materials: Features an internal structure of vertically stacked large-diameter brass elements supported by a high-class aluminum alloy base pipe, ensuring long-term electrical stability and corrosion resistance.
• Versatile Mounting Options: The design allows for direct mounting into vehicle roof-top holes or equipment chassis. Optional pole-mounting hardware is available for fixed-site or temporary TOC (Tactical Operations Center) deployments.
• Environmental Finish: Supplied in Military Olive Green, the antenna is designed to maintain a low visual signature while operating in temperatures ranging from -30°C to +70°C.

Technical Features

• Unified UHF SATCOM Solution: Optimized for the critical 243–318 MHz tactical window.
