  • ICE 3000 Series

    ICE3006 - Pole/Zero

    The ICE3006 is an agile filter/amplifier cascade for the UHF frequency band with a VHF bypass. It enables simultaneous operation of multiple transceivers in the cosite environment. This filter/amplifier provides multiple poles of RF selectivity to reduce broadband noise, harmonics, and spurious signals while still providing full output power in transmit mode and excellent selectivity to interfering signals at the transceiver’s RF input in receive mode. All transmit, receive, and bypass switching is incorporated into the three-port design (LOS and SATCOM). The ICE3006 incorporates extensive Built-in-Test capability and is qualified for airborne applications. A mounting tray is available as an option for easy incorporation on your platform. Cost-effective modifications are available on the ICE3006. Please contact your sales representative at 513.870.9060 or Support@PoleZero.com for details.

  • Mini Bug Detector II

    P7050 - P3 International Corp.

    Peace of mind is now within your reach. The Mini Bug Detector™ offers state of the art protection against wireless microphones and transmitters. Perfect for securing homes, offices and hotel rooms, the unit not only detects such devices, its LED display and audio tone actually pinpoint the precise location of bugs. The audio alarm can be turned off for discreet sweeps, while the unit’s sensitivity adjustment minimizes false alarms. The Mini Bug Detector™ features wide range circuitry that enables it to detect concealed transmitters operating on frequencies from 50 MHz to 3 GHz, exposing most high frequency transmitters as well as more common VHF and UHF bugs. You didn’t know they were listening…until now.

  • ICE 3000 Series

    ICE3005 - Pole/Zero

    The ICE3005 is an agile filter/amplifier cascade for the UHF frequency band with a VHF bypass. It enables simultaneous operation of multiple transceivers in a cosite environment and is factory configured for an ARC-210 interface. This filter/amplifier provides multiple poles of RF selectivity to reduce broadband noise, harmonics, and spurious signals while still providing full output power in transmit mode and excellent selectivity to interfering signals at the transceiver’s RF input in receive mode. All transmit, receive, and bypass switching is incorporated into the two-port design. The ICE3005 also includes a separate audio processor circuit that mitigates popping and drop-outs in the R/T audio that are common in hopping or blanked waveforms. The ICE3005 incorporates extensive Built-in-Test capability and is qualified for military applications. A mounting tray is available for easy incorporation on your platform. Cost-effective modifications are available on the ICE3005. Please contact your sales representative at 513.870.9060 or Support@PoleZero.com for details.

  • VECTOR-GUN HANDHELD DIRECTION FINDING ANTENNA SYSTEM

    HFDF - National RF, Inc

    National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.
