VHF/UHF Handheld Signal Location Antennas
Type NVF-2
The Type NVF-2 series of handheld directional antennas are used to locate interfering signals or noise in either the 420 – 470 MHz (Type NVF-2A) or the 900 MHz ISM band or cellular telephone bands (Type NVF-2B). Both models incorporate a solid reflector positioned behind a resonated half wave driven element, both elements being mounted on a fiberglass rod with an integral pistol grip. The configuration of the reflector and driven element are such that a deep null in the signal being received will occur when the antenna is pointed in the direction of the signal being radiated. A T-pad resistive attenuator is also incorporated in the antenna mounting enclosure to aid in the direction finding process on very strong signals or when excessive reflections present multiple returns.

GPS/GNSS Antenna Signal Splitter 2-Way, TNC Female, IP67 Weatherproof, 1-2 GHz
GPS221
INSTOCK Wireless Components, Inc
GPS221 is a two way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between two receivers while providing a DC current path to power a remotely located active GPS antenna from one receiver while blocking the DC path from the other. Furnished with TNC female connectors all ports. A special feature of this unit is the 200 ohm internal load which provides a current drain for the GPS receiver not powering the active antenna. Some GPS receivers incorrectly sense an antenna fault when there is no current draw. The 200 ohm internal load provides a simulated antenna current drain which prevents receiver faulting. Max voltage rating at the DC blocked port is 15 VDC; maximum current rating is 75 mA. Max voltage rating at the DC pass port is 50 VDC; max current rating is 2000 mA.

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.

Automatic Antenna Tuner 3.5 kW
DU 3500 AL
The DU 3500 AL automatic tuner has been primarily manufactured for an automatic PA, but it can also be used with any manual PAs as well. The tuner is primarily compatible with the OM POWER automatic PA.This tuner was designed for antennas calibrated to HAM BANDs. The maximum power can only be utilized with these antennas. With other antennas, it should be set at a lower power (max. 2kW).The major advantage of the tuner is that during competitions it is possible to change BANDs particularly quickly.
