The MA4000-DG antenna mast is suitable for use in either open areas or in electromagnetic absorption chambers. Guy wires and anchoring pins are available for antenna installation in open areas. Metal parts are located only in the base plate and the drive mechanism (max. 0,3 m above ground level).

Adapters for all commerically available antennas are available. Special designs are available on request. All antennas during polarisation rotate around their axis so as to eliminate any elevation errors.

The IEEE 488 (GPIB) bus, when operated with the CO2000 Controller, or IEEE 488 (GPIB) & TCP/IP (LAN) interface, when operated by CO3000 Controller provides an additional control option for all functions.
