New HMAM makes first IBC appearance

The latest version of the HMAM high-precision motorised satellite antenna mount is being showcased, designed for two-way VSAT communication or receive-only downlink applications. It can be used for a wide range of applications including broadcast and telecoms downlinks.

The HMAM is being shown in compact form for up to 2.4m diameter dishes. Making its first exhibition appearance is a new motorised feedchanger which allows the head to be moved quickly to a new position for switching between two different frequency bands. The system comes complete with drives for azimuth and elevation plus a high-accuracy polarisation drive.

The combined head and drive form a three-axis motorised system with 180 degrees of azimuth adjustment, 90 degrees of elevation adjustment range and fully adjustable polarisation.

The HMAM-IOT variant incorporates inclined-orbit tracking. To conserve guidance propellant, older satellites are allowed to drift further from their nominal target position than during their main service life. Operators therefore offer greatly reduced transponder capacity pricing. The HMAM-IOT’s tracking capabilities enable the antenna to follow these variations in position.
