A.H.Systems, Inc.
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.

ARA 01 -
York EMC Services Ltd
The Active Receive Antenna (ARA 01) is a compact emissions antenna with an antenna factor comparable to a conventional wideband passive antenna such as the Bilog. The small size makes the ARA 01 particularly suitable for use in anechoic chambers; however it can also be used on an Open Area Test Site (OATS) or at on-site locations.

AD-100 -
Com-Power Corporation
The Tuned Dipole Antenna model AD-100 is a reference antenna set specified in many EMC standards. It is used in the frequency range of 30 MHz to 1 GHz. This set consists of four baluns and was designed according to American National Standard C63.4. This reference antenna set is used for EMC test site calibrations and for calibrating other antennas, because it is considered a standard antenna according to ANSI C63.5 standard.

Spirent Federal Systems
The Spirent CRPA Test System is a development of Spirent’s GSS9000 Series platform for testing Controlled Reception Pattern Antenna (CRPA) systems with a separate RF output per antenna element. The CRPA Test System generates both GNSS and interference signals. Users can control multiple antenna elements. Null-steering and space/time adaptive CRPA testing are both supported by this comprehensive wavefront approach.

Radio Frequency Systems
Cable testing sections may be used to isolate the antenna inputs from the main feeder when testing either the antenna or feeder. These devices are normally installed between the main feeder cable and antenna inputconnector and allow access to the antenna input without the need to remove the main feeder cable. Cable test sections are particularly useful with large feeder cables that are difficult to manoeuvre.

Antenna Research Associates
Antennas for RADAR test, simulation and training are designed for integration into complete threat RADAR simulators for use on combat training and test ranges or in simulators for training and evaluation of RADAR operators, aircrews, air-traffic-control or weather radar applications. All antennas for RADAR simulators have high RF power handling capabilities and generally use pressurized transmission lines. Dual-band, single aperture antennas and a cluster of separate antennas mounted to a single pedestal are ideally suited for RADAR simulators in mobile, fixed, shipboard and airborne environments.

SG1000B/PR1000A -
Praxsym
The SG1000 Signal Generator and PR1000A Preamplifier have been designed to simplify the measurement of shielding integrity in a shielded enclosure. When coupled with a high stability spectrum analyzer and an appropriate selection of test antennas, the SG1000/PR1000A combination can measure shielding effectiveness at all of the NSA 94-106 (supersedes NSA 65-6) defined test frequencies from 1 kHz to 10 GHz.The PR1000A amplifies the received signal from the test antenna and overcomes the high noise figure of the companion test receiver or spectrum analyzer. The PR1000A will ensure that the system noise figure will be less than 4.5 dB at all test frequencies from 1 kHz to 10 GHz. When used with a spectrum analyzer measurement bandwidth of 100 Hz, the system exhibits a sensitivity of -150 dBm at the test antenna output.To overcome high cable loss between the test antenna and the PR1000A assembly at 10 GHz, a remote low noise pre-amplifier (Praxsym PN 310-010091-001) is mounted directly onto the 10 GHz antenna.
