The PALS PFMA-750 is a high-performance antenna system engineered to meet or exceed stringent global standards. It features a highly efficient design that ensures superior gain, low sidelobes, and a high G/T ratio for optimal communication efficiency. Its robust construction utilizes hot-dip zinc processed steel parts for maximum corrosion resistance in harsh environments.
Designed for maximum versatility, the PFMA-750 supports a wide spectrum of frequency bands including C, Ku, Ka, as well as customized L, S, and QV band options. It offers flexible configurations such as Rx/Tx or 2Rx/2Tx, and multiple structure types including A+E and X-Y to meet diverse operational requirements.
The antenna is delivered as a comprehensive turnkey solution, ideally suited for Telemetry, Tracking, and Command (TT&C), mobile deployments, and critical communications. It includes a full suite of optional accessories such as the antenna servo system, de-icing components, BUCs, LNBs, modems, and more to ensure immediate and reliable operation.
