Antenna Masts

EMC antenna masts provide precise vertical positioning of measurement antennas for radiated emissions height scans as required by CISPR 16-1-4, ANSI C63.4, and EN 55016-1-4. Constructed from non-conductive materials such as wood, fiberglass, and PTFE composite with no metal fasteners, these masts eliminate field perturbation and ensure measurement integrity. The standard height range is 1–4 m per CISPR requirements, extendable to 6 m for MIL-STD-461 applications, with stepper-motor drive systems delivering ≤1 cm positioning accuracy and ≤5 mm repeatability. Automated horizontal/vertical polarization switching and tilt mechanisms for above-1-GHz horn antennas are supported, with seamless integration into R&S, Keysight, and ETS-Lindgren test automation software.
