Broadband Antennas (RF200 & RF230)

High performance EMC antennas to cover the range 30MHz – 4GHz

The RFxxx range are specifically designed for general use as EMC emissions measurement antennas. They combine excellent broadband characteristics with high sensitivity and sturdy construction. Although primarily used with the Laplace range of analysers and receivers, they can be used with any other receiver and are supplied with full calibration data so that antenna factors can be entered into any third party system.

In order to achieve optimum performance consistency, the RF200 is designed to work with the SA1020 pre-amplifier, located at the head of the support tripod. This improves sensitivity and ensures that cable configuration does not affect results.

The RF200 is supplied complete with rigid adjustable stand and the RF230 is complete with an all plastic miniature tripod.
