Frankonia provides a broad range of positioning devices such as standardized and multi-use turntable systems and antenna masts, which are designed and developed by Frankonia’s own R&D department. Frankonia considers highest quality and technology standards respecting the latest EMC standard requirements.
Range of products
Turntable Systems
FTM – Turntable Systems
Frankonia’s wide range of turntables is fully compliant with the EMC chamber environment. The turntables are available in different sizes and can be equipped with various options. They are integrated flush in the raised floor and are surrounded by a conductivity grounding ring to ensure the contact with the ground plane of the chamber. For the control of the turntable series FTM, the Frankonia controller FC06.1 is perfectly adapted using the IEEE 488.2 (GPIB) commands.

Antenna Mast Systems
FAM – Frankonia Antenna Mast
The FAM is Frankonia’s standard antenna mast solution compliant according to CISPR 16-1-4. For customers’ convenience, the Frankonia antenna mast is 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
FBM – Frankonia Boresight Antenna Mast
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.

Features
Operation modes
FSM – Frankonia Antenna Stand
The FSM is Frankonia’s standard manual antenna mast solution. The height level of the double telescopic antenna masts FSM1.6 and FSM2.0 can be adjusted manually. To avoid unwanted reflections, the mast rods are made of fiber glass. A collapsible tripod provides a secure stand and easy adaption. The perpendicular mast adjustment is simplified with a spirit level mounted at the tripod. Antennas can be mounted directly on the 3/8” male thread or using adapters for double stacked antennas.
The main application of FSM4.0 is 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 FSM4.0 tripod is suitable for both stationary and mobile applications. The antennas are mounted with their 22mm tube directly to the support, the polarization device is fixed with an indexing ring for both, vertical and horizontal polarization.
The polarization device FPD-01 is an electrical unit to adjust the polarization of antennas. The maximum weight of antennas is 5 kg with a 90° polarization range. The FDP-01 polarization device has an antenna tube of 22mm, which is equipped with a clamp ring for easy and safe installation of antennas. On the side, a 3/8-16 UNC thread is foreseen for the installation to a FSM antenna stand. The software operation requires a FC06.1 controller with 24V output.
