Product Details

Looking for the perfect for low frequency omni-directional antenna. The SAS-550-1B active monopole antenna is ideal for instantaneous bandwidth scanning (without tuning) of electric fields from 9 KHz - 60 MHz. It's well suited for test technicians performing FCC, MIL-STD and TEMPEST low frequency tests. A fully charged hefty 2000 mAH battery will last a full work day for continuous testing, and this 104cm rod antenna has a signal output connector that is electrically bonded to the matching network case per MIL-STD 461F. This model boasts A.H. Systems' amazing 3 year warranty too, so you've got complete peace of mind.

The SAS-550-1B 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-550-1B Antenna Base with ground plane
  • Telescoping Antenna Element
  • Battery Charger
  • Antenna Calibration Manual

* Calibration data and certificate included.
