Double Ridge Guide 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.
A.H. Systems Double Ridge Guide Horns are broadband antennas that offer excellent performance over the frequency range of 170 MHz to 40 GHz. These Horn antennas are an excellent choice for both radiated immunity and emissions testing. Here are several double ridge guide horn antennas ideal for most compliance testing and/or general field measurements.

Standard Gain Horns
The Standard Gain Horn Antennas
are designed specifically for utilization in emissions and immunity
testing over the frequency range of 1 to 40 GHz. Each antenna
is linearly polarized and has medium gain, low VSWR, and constant
antenna factor. The Standard Gain Horn performance is very precise
and predictable through design parameters. Comparisons of measured
versus computed antenna factors and gain have been shown to be
+/- .5 dB. Therefore, the antenna is considered to be a standard
reference, similar to that of a resonant dipole below 1 GHz. The
coax-to-waveguide adapter is the only power-limiting component
on the antenna and can be removed if high fields are desired.
Each Standard Gain Horn comes with a tripod mount that adapts
to any tripod with ¼-20 male threads. Horizontal and vertical
polarization is obtained by rotating the antenna on the tripod.
Gain:
15 dB, also available in 10 dB or 20 dB gain.
