Product Details

Our SAS-550-2B Active Monopole Antenna provides superior performance in electric field measurements. This antenna can drive any receiver with 50 ohm input impedance and will perform FCC, MIL-STD and TEMPEST tests. The antenna is powered by a 2000 mAh battery pack will last a full work day for continuous testing.

We have re-designed our active monopole antenna and changed the input connection from a BNC connector to a more rugged 1/4-20 threaded attachment.

The SAS-550-2B comes with a telescoping rod, ground plane, high impedance matched preamplifier and battery charger.

*** As of Dec-2019 ***

All new active monopole antennas have been re-designed to accept a telescoping rod with a 1/4-20 thread instead of a BNC connector. This new connection makes for a better electrical performance as well as an improved rugged design.

Please note that this new design will not accept the use of the ECF-10 (with the BNC connector) please refer to the new ECF-10K Equivalent capacitance fixture kit that will also inlude a BNC tee and 50 ohm load (all of which is required to preform an antenna systems check).

    Included parts:
  • SAS-550-2B Antenna Base with ground plane
  • Telescoping Antenna Element
  • Battery Charger
  • Antenna Calibration Manual

* Calibration data and certificate included.
