The EM-6961 Double Ridged Guide Antenna is a linearly polarized broadband antenna designed and built specifically for EMI measurements and specification compliance testing.

The versatile EM-6961 is constructed of rugged aluminum, which makes it excellent for use under severe field conditions and the size makes it suitable for use in the limited space of a shielded enclosure.

Applications

The EM-6961 is a linearly polarized antenna capable of operating as either a transmitting or receiving antenna.

Exhibiting highly efficient performance characteristics for a broadband antenna, the EM-6961 is ideal for measurements to meet MIL-STD-461/462 EMI specifications. It is also well suited for radiated susceptibility testing in the microwave range and general transmitting and receiving applications. Antenna factor chart supplied with each antenna.
