VECTOR-GUN HANDHELD DIRECTION FINDING ANTENNA SYSTEM
HFDF
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.

Rectangular Horn Antennas
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz.
