The SYST-A0005 is a shipborne rotatable antenna used for wideband detection and monitoring of communication signals.
The SYST-A0005 is a shipborne rotatable antenna system used for wideband detection and monitoring of communication signals. It consists of two LPDA antennas fitted to a single vertical mast, mounted on a rotator. The rotator can be aimed at all angles and is controlled via software.
The LPDA-A0083 is a large LPDA for 30 to 1000 MHz and is mounted on top of the mast. The LPDA-A0084 is a small LPDA mounted at the base of the mast. The SYST-A0005 features low-loss internal cables, a rotary joint for unlimited continuous rotation and a protected cable exit system.
It is designed for shipboard use above deck and has been tested to withstand a 200 km/h wind speed. All components are stainless steel and aluminium for complete protection from salt. The antenna has ample power capability for immunity from nearby communications and high power transmitting. The mast has an integrated fold-away hoisting boom to facilitate installation with a crane.
