Detachable Antenna Mast System (glass-fibre tubing) for VHF-UHF Antennas.
The main application of AM 9104 is the measurement of radiated emission with antennas where frequent height scans are required. The mast can be set up and disassembled without any tools within 2 minutes. Due to its small transport dimensions it can be stored without problems even in small cars. The antennas are mounted with their 22 mm tube and indexing ring directly into the antenna support. The polarisation is fixed by a latching mechanism in the antenna support that uses the indexing ring mounted to any Schwarzbeck antenna. There is no additional adapter needed to accept antennas with 22 mm tubes. A bubble level is mounted on the tripod to enable a convenient perpendicu-lar adjustment of the three leg spider on uneven ground. The spider legs can be equipped with caster wheels with brakes optionally.
