Horn

The Model ATH18G27 is a wide band, high gain, high power microwave horn antenna. With a minimum gain of 18.8dB over isotropic, the Model ATH18G27 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

These millimeter wave standard gain conical and pyramidal horns feature a low cost, low VSWR, and a light weight. They’re ideal for applications involving antenna measurements and array elements, and can also be used as feeds for prime focus and Cassegrain antennas.

The Model ATH26G40 is a wide band, high gain, high power microwave horn antenna. With a minimum gain of 18.9dB over isotropic, the Model ATH26G40 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

The A.H. Systems' Double Ridge Guide Horn Antenna is a broadband antenna that offers excellent performance over the frequency range of 1 GHz to 4 GHz. High gain, low VSWR, input handling capability up to 250 watts CW, and rugged design make this horn antenna excellent for both immunity and emissions testing.

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.

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 a constant antenna factor.

Narda Standard Gain Horn Antennas are precision antennas designed to be used as standards for calibrating other antennas; as feed horns for reflectors and lenses; as pick-up horns for sampling power; and as receiving and transmitting antennas. The high frequency models (18-40 GHz models) are precision bronze castings; intermediate-frequency models (2.6-18 GHz models) are precision aluminum castings.

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 a constant antenna factor.
