AH-840 Horn Antenna

The model AH-840 Horn Antenna is designed to be used in an EMI laboratory to
measure and/or to generate electro-magnetic E (electric) fields.

Generating Electro Magnetic Fields:

The model AH-840 antenna should be operated by trained personnel in the
field of  EMC for the purpose of generating electro-magnetic fields. Test location
should be carefully selected to avoid interference to other equipment and
exposure of personnel to high electromagnetic fields.

Maintenance and Service:

There are no user serviceable parts in the antenna. However, the user should peri-
odically check the antenna for any deformed elements or dents on the antenna
caused by accident during use. Com-Power recommends calibration of the an-
tenna be checked once a year (If used in accordance to ANSI C63.4-1992 Section
4.4 Calibration of Measuring Equipment). Com-Power provides calibration ser-
vice for all equipment sold. Call the factory if calibration or other service is de-
sired.
