The Model 6507 Active Shielded Loop Antenna produces good sensitivity and almost constant antenna factors, when testing for EMC applications. The 6507 has a pre-amplifier that activates a saturation indicator if the incoming signal exceeds 5 V/m limit. Power for this pre-amplifier is provided by rechargable, sealed batteries.

The antenna features a front control panel where power switches and indicators are located. A switch selectable battery charger for either 115 VAC or 230 VAC 50/60 Hz is included.

Every loop antenna is individually calibrated in accordance with ANSI C63.5.
