AH-118 Horn Antenna

The Model AH-118 Horn antenna were designed for use in an EMI laboratory to
measure or generate electric fields.

Test Operator and Test Location:

The Model AH-118 antenna should be operated by trained personnel in the
field of  EMC for the purpose of generating electromagnetic fields. Test location
should be 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 antenna at
least once a year.   

Com-Power 

provides calibration service for all equipment

sold. Call the factory if calibration or other service is required.
