Monopole/Dipole

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.

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 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.

The A.H. Systems' SAS-530 Broadband Dipole Antenna operates efficiently over the frequency range of 160 MHz to 500 MHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, this antenna will provide reliable, repeatable measurements. Whether testing outdoors, or in a shielded enclosure, the rugged construction of the Broadband Dipole makes it suitable for all conditions.

The TV-2 is a tuned dipole antenna from A.H. Systems that operates within the 325 MHz to 1000 MHz frequency range.

The TV-1 is a tuned dipole antenna from A.H. Systems that operates in the  50 MHz - 220 MHz frequency range.

Model TDS-535 Tuned Dipole Set provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.5). This half wavelength dipole set is manufactured per the FCC balun design and is individually calibrated per ANSI C63.5 at 3 and 10 meters.
