The ASC Signal 3.9 Meter Trifold™ is a transportable satellite antenna system, designed for use worldwide in various applications serving data, voice and communications networks.
A broad range of adjustments provides non-critical Positioner/Trailer orientation and the ability to view geostationary satellites, horizonto-horizon, from any location worldwide. The system provides a high quality and dependable antenna platform, supported by the ASC Signal Corporation service and support network.
The electrical performance and versatility allows the ability to configure the antenna with a variety of transmit and receive feed assemblies. This versatility provides the ability to configure the antenna with multiple linearly or circularly polarized C-band, X-band, X-band Low Passive Intermodulation (PIM), Ku-band, K-band, and Ka-band feed systems. Each feed system has been designed to be easily removable for transport.
The antenna system design consists of a spun aluminum reflector, a removable subreflector, heavy duty elevation over azimuth Positioner, and an optional heavy duty Trailer for transport.
