Monopole/Dipole

A.H. Systems FCC-4 half-wave dipole antenna, consisting of a matching balun, two horizontal elements, and a mounting clamp and tape measure to adjust the element lengths, is the simplest form of antenna.

The FCC-1 is a tuned dipole antenna operating in the 25 MHz - 70 MHz frequency range.

The SAS-550-1B Active Monopole Antenna is an active, general-purpose, receive-only antenna that covers 9 KHz - 60 MHz frequency range. It is ideal for instantaneous bandwidth scanning (without tuning) of electric fields in its frequency range and can drive any receiver with 50-ohm input impedance.

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.

The A.H. Systems' Tuned Dipole Set provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.4). Each Tuned Dipole Set is manufactured per the FCC balun design and is individually calibrated. 

The SAS-530H is a broadband dipole from A.H. Systems that operates in the 160 MHz to 500 MHz frequency range.

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.

This Equivalent Capacitance Fixture is used for the verification and calibration of the active monopole antennas.
