HOT PRODUCTS

<B>Biconical Antennas</b> Biconical Antennas

A.H. Systems has designed and manufactured a family of 7 biconical antennas that operate efficiently over the 20 MHz to 18 GHz frequency range. Each antenna is made to provide reliable, repeatable measurements and is suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing.

<B>Bilogical Antennas </b> Bilogical Antennas

For rapid deployment along with the mobility of small package, these Bilogical Antennas and Kits provide an inexpensive solution to broadband applications.

Current Probes Current Probes

A.H. Systems offers Current Probe devices designed to be used in generating and measuring high levels of RF current, and in many industrial and scientific applications. They can be used to measure conducted currents without making direct contact with the source conductor or metallic surface.

<B>Dipole Antennas</b> Dipole Antennas

A.H. Systems offers a range of half wavelength resonant dipole antennas with operation frequencies between 25 MHz and 3 GHz as the foundation of every compliance testing lab. Ideal for site attenuation measurements, each antenna is manufactured with a balun loss of less than 0.5 dB and a VSWR ratio of less than 1.5:1.

<B>H-Field Rods </b> H-Field Rods

The A.H. Systems' set of H-Field Rods provide an accurate standard for magnetic field testing. The rods are available individually or in a set of four to cover the frequency range of 100 Hz to 30 MHz.

<B>Horn Antennas</b> Horn Antennas

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. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.

<B>Log Periodic Antennas</b> Log Periodic Antennas

A.H. Systems' offers 13 Log Periodic Antennas. Each antenna is lightweight, compact, rugged and has been manufactured to ensure maximum gain, low VSWR and high power handling capabilities.

<B>Loop Antennas </b> Loop Antennas

A.H. Systems' designs, manufactures and delivers high performance Loop Antennas for a wide range of magnetic field testing. Whether used in a set to measure shielding effectiveness per MIL-STD 285 and NSA 65-6 or individually to satisfy specific requirements, the Loop Antennas are an efficient, low cost solution.

<B>Monopole Antennas</b> Monopole Antennas

A.H Systems presents Monopole Antennas designed to provide superior performance in electric field measurements. Active Monopole Antennas are capable of driving any receiver with 50W input impedance, and can perform FCC, MIL-STD, and TEMPEST tests.

<B>Low Noise Preamplifiers</b> Low Noise Preamplifiers

A.H. Systems' Preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 20 dB.

<B>Cables, Adapters And Accessories</b> Cables, Adapters And Accessories
