Hiltron announces HMFC motorised feed-change antenna mount

Hiltron has chosen IBC2014 as the venue for the introduction of the new HMFC motorised feed-change antenna mount. The HMFC allows easy positioning of repositioning of waveguide horns on a motorised tray table. It can be used for antennas of various types and sizes.

Two waveguide horns of different sizes can be attached, allowing signals from satellites operating in two different frequency bands to be received electrically selectable via a single antenna. Movement of the table is controlled via the Hiltrons HACU antenna control software. The waveguide horn for a desired frequency band can be aligned into the focal point of the reflector within 20 seconds.

The Hiltron HMFC can perform automatic changeover of the operational feed as well as sequential measurement of different frequency bands. Available options include inclined-orbit tracking, high-accuracy optical encoders, extended temperature tolerance and increased protection against exposure to salt water. A handheld control for manual alignment, plus integral de-icing can also be specified.

Operation is via an IP-connected PC. The HMFCs control GUI displays all the information required to set and maintain azimuth, elevation and polarisation, including current position, target position and a database of potentially accessible satellites. Once a satellite is selected, precise access parameters can be calculated at the press of a single button. Azimuth and elevation can be adjusted at up to three different speeds. Typical travel rates are 2.5 degrees per second (azimuth), 1.7 degrees per second (elevation) and 3.0 degrees per second (polarisation).

Azimuth movement is accomplished via an axle bearing with a drive motor. Elevation movement is via a jackscrew with a further drive motor. This design, combined with the use of resolver-angle indicators, provides highly reliable positioning far beyond the stability and precision of commercial-grade actuator devices. The very high rigidity of the construction ensures essentially zero backlash. The HMFC can operate in winds of up to 125 kilometres per hour and survive gusts of up to 200 kilometres per hour.
