H-064A Fixed Satcom Antenna
The H-064A Fixed Satcom Antenna is a high-gain, directional UHF helical antenna engineered for military and defense satellite communications. Operating across the 225–400 MHz UHF frequency band, it provides wideband coverage supporting legacy UHF Follow-On (UFO) SATCOM systems as well as the next-generation Mobile User Objective System (MUOS).
Description
The H-064A Fixed Satcom Antenna is a high-gain, directional UHF helical antenna engineered for military and defense satellite communications. Operating across the 225–400 MHz UHF frequency band, it provides wideband coverage supporting legacy UHF Follow-On (UFO) SATCOM systems as well as the next-generation Mobile User Objective System (MUOS).
Its frequency range encompasses the full uplink and downlink bands used by both UFO and MUOS networks, making the H-064A well-suited for platforms requiring dual-system compatibility during SATCOM transition and mixed-fleet operations. Designed for mission-critical applications, the antenna delivers consistent, high-quality signal transmission while maintaining reliable performance in harsh and demanding operational environments.
