H-065 Fixed Satcom Antenna
The H-065 Fixed SATCOM Antenna is a directional UHF antenna operating across the 300–520 MHz frequency range. It is designed to support next-generation Mobile User Objective System (MUOS) satellite communications, delivering reliable performance for mission-critical military and defense applications.
Description
The H-065 Fixed SATCOM Antenna is engineered for military and defense satellite communications requiring dependable performance in harsh operational environments. Operating within the 300–520 MHz UHF frequency band, it provides directional coverage with 12 dBi gain at 520 MHz and right-hand circular polarization (RHCP) to support stable and efficient satellite links.
The antenna’s frequency coverage includes both the uplink (300–320 MHz) and downlink (360–380 MHz) bands used by the Mobile User Objective System (MUOS), making the H-065 well suited for modern UHF SATCOM networks and MUOS-based ground systems. Designed for fixed, mission-critical installations, the H-065 combines robust construction with precise RF performance to ensure long-term reliability and consistent connectivity in extreme environmental conditions.
