2.4m Troposcatter auto-point ‘Flyaway’ antenna system

The Tropoline 240 auto-point troposcatter terminal is designed as a robust, light-weight and easy to use Flyaway for C-band communication over long distances.

GENERAL DESCRIPTION

This 2.4m fully automated motorized troposcatter and line-of-sight (LOS) flyaway terminal is made of state-ofthe-art composite segmented light weight reflector and military grade pneumatic mast with a quadpod base for high stability. The system comes complete with hand pump for easy deployment of the mast and extension to 3m to clear obstacles. The center-fed architecture reduces antenna signal blockage leading to increased antenna efficiency. Its highly robust design allows it to operate safely in steady winds of 80kph and gusts of 108kph when properly deployed and guyed.

The antenna and RF components are packaged in rugged cases, the mast and its accessories are packaged in military grade bags.

ANTENNA CONTROL UNIT

The Antenna Control Unit (ACU) includes all sensors for positioning, orientation, monitoring and control.

MAST AND POSITIONER

The pneumatic telescopic mast and elevation over azimuth positioner are designed for robustness and reliable operation in all weather conditions in all environments and comply with MIL STD 810G as described below.

MULTI BAND ANTENNA SYSTEM

The center-fed antenna system is comprised of a light weight axisymmetric composite reflector, manufactured with high tolerances to provide excellent sidelobe and cross-polarisation performance.

INTEGRATION POSSIBILITIES

Requtech is able to provide a complete turnkey system by integrating modem, SSPA and LNB.

Currently designed to work (and optionally supplied) with the Datum Systems M7 modem.

SSPAs up to 2kW can be either installed on the ground or on a shelf mounted on the quadpod base, whichever best suits the application. LNBs can be optionally provided.

Troposcatter Communications are used for beyond line of sight (over the horizon) point to point communications between remote geographic areas where cable links are not feasible. A troposcatter system has an antenna at both ends, capable of both transmitting and receiving signals.
