PXY-750 offers exceptional pattern characteristics and a high gain. The possibility to configure the antenna with a circularly or linearly polarized multi-port combining network contributes to its exceptional versatility and high RF performance. This antenna solution is a durable and dependable antenna system capable of operating efficiently in S, C, X, Ku, or Ka bands while successfully withstanding environmental conditions. Main reflector, sub-reflector, mount assembly, back struts, and feed assembly comprise the antenna. The aluminum alloy reflector is precision formed to ensure strength and accuracy while requiring little maintenance.
The primary reflector assembly is divided into multiple parts in order to facilitate transportation to remote locations and decrease the overall shipping volume. After conversion coating and painting with a highly reflective white paint, the reflector panels are completed. A mount made of hot-dipped galvanized steel ensures pointing precision, durability, and dependability. The capacity to track LEO/MEO/GEO satellites will be ensured by the S/X band feed with MONOPULSE capabilities.
