The PALS PFMA-620 is a high-performance, servo-controlled auto-pointing antenna system for critical satellite communications. It excels in TT&C (Telemetry, Tracking & Command), TX/RX, and RX-only applications across C, X, Ku, and Ka frequency bands.
Engineered for precision, its robust construction with formed panels and a machined hub ensures high gain and excellent radiation patterns. The system provides exceptional pointing flexibility with continuous 360-degree azimuth rotation and 85-degree elevation for full horizon-to-horizon satellite tracking.
Ideal for a wide range of uses—including TV distribution (DTH/SNG), data networks, emergency response, and mobile deployments—it delivers reliable connectivity for both fixed and on-the-move operations. Integrated with the reliable PALS Antenna Controller for fast, stable satellite acquisition, the PFMA-620 is supported by a complete suite of accessories for turnkey solutions, including servo/power systems, BUCs, LNBs, modems, and installation kits.
