Founded in 1985, the company specializes in designing and producing broadband antennas, antenna kits, and low-noise preamplifiers used in electromagnetic compatibility (EMC) testing environments. AH Systems products conform to international standards including ANSI, CISPR, MIL-STD, and FCC requirements.

AH Systems antennas cover a wide frequency range, from below 20 MHz to above 18 GHz, making them suitable for both radiated emissions and immunity testing in open area test sites (OATS), semi-anechoic chambers, and shielded rooms.

Key Product Lines

• Biconical Antennas: for radiated emissions measurements in the 20 MHz to 300 MHz frequency range per CISPR and FCC standards
• Log-Periodic Antennas: broadband directional antennas covering 200 MHz to 18 GHz for emissions and immunity testing
• Antenna Kits: pre-configured sets providing complete frequency coverage for full EMC test compliance
• RF Preamplifiers: low-noise amplifiers boosting signal sensitivity for accurate sub-threshold measurements

Industries Served

AH Systems equipment is used in accredited EMC test laboratories, defense electronics qualification testing, FCC and CE certification facilities, and engineering departments developing wireless devices, automotive electronics, industrial control systems, and consumer electronics.
