The TW4000-EP antenna mast is suitable for use in either open areas or in electromagnetic absoption chambers. Metal parts are located only in the base plate and the drive mechanism (max. 0,4 m above ground level).
Adapters for all commercially available antennas are available. Special designs on request. All antennas during polarisation rotate around their axis so as to eliminate any elevation errors. Limit switches and the general mechanical design ensures a reliable system operation.
The GPIB (IEEE 488) bus, when operated wit the CO2000 Controller, or GPIB (IEEE 488) & LAN (TCP/IP), when operated by CO3000 Controller provides an additional control option for all functions.
