The MM4000-PP 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. The MM4000 antenna mast has no metal parts above the drive unit. Special designs are available upon request. The mast tube can be delivered in 2 seperate parts for easy transportation and storage.
Adapters for all commercially available antennas are available. Special designs are available on request. All antennas rotate around their own axis during polarisation to eliminate any elevation errors. Limit switches and the general mechanical design ensure a reliable system operation.
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.
