Electrical Polarization Switch
The polarization device FPD-01 (1) is designed for the polarization of antennas. The maximum weight of antennas is 5 kg, slewing range 0° – 90°. The FDP-01 polarization unit has an antenna tube of 22mm, which is equipped with a clap ring for easy and safe installation of antennas. On the side a 3/8-16 UNC thread is foreseen for the installation of a stand. The control is effected with the controller FC06-24V. The control signal is feed through the shielded wall via an EMC filter that is mounted on the carrying unit. (2)

Manual Antenna Masts
The height level of the double telescopic antenna masts FSM-1.6 and FSM-2.0 can be manually adjusted from 0.9 / 1.2 m to 1.6 / 2.0 m (depending on the model). The continuous height setting is made within a few seconds. In order to avoid unwanted reflexions the mast rods are made of fibre glass. A collapsible tripod provides a secure stand and easy adaption to uneven ground. The perpendicular mast-adjustment is simplified with a spirit level mounted at the tripod. A rotatable spider fixes the tripod-legs for easy movement within seconds by one person only. Antennas can be mounted directly on the 3/8” male thread or using adapters for double stacked antennas.

The main application of FSM-4.0 are emission measurements, where frequent height scans are required. Level adjustment from 0.4 m to 4.15 m can easily be done by using the manual winch. The mast can be setup and disassembled without any tools within 2 min. The FSM-4.0 tripod is suitable for both stationary and mobile applications. Thanks to its small transport dimensions it can be stored without problems even in small cars. The antennas are mounted with their 22 mm tube directly to the support, the polariza- tion is fixed with an indexing ring for both, vertical and horizontal polarization without tools. There is no additional adapter needed to accept antennas with 22 mm tubes. Each of the three spider legs can be adjusted individually for a coarse level adjustment on uneven or inclined mounting.

Fully Automatic Antenna Masts
The FAM is Frankonia’s standard antenna mast solution compliant according to CISPR 16-1-4. For customers’ convenience, the Frankonia antenna mast are equipped with wheels and can be folded to enable easy transportation and handling. To reduce unintentional reflections, the masts are made of fiberglass and plastic materials. Any reflecting materials have been reduced to a minimum.
Features

Based on the FAM antenna mast construction, the FBM boresight antenna mast is compliant with ANSI C63.4 and CISPR 16-1-4 that includes an advanced tilt function. To offer full flexibility, the tilt function can be switched off, so that the FBM operates as a standard mast. Within the tilt function, the FBM software automatically calculates the tilt angle in accordance with the antenna specific reference point, as well as distance, position and size of the EUT and monitors the complete test procedure.
