Horn

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 Model ATH26G40-1 is a wide band, low gain, wide beamwidth, high power microwave horn antenna. With a minimum gain of 8.6dB over isotropic, the Model ATH26G40-1 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

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 A.H. Systems' Horn Antenna is a broadband antenna that offers excellent performance over the frequency range of 18 GHz to 26.5 GHz. High gain, low VSWR, and input handling capability up to 50 watts make this horn antenna excellent for both radiated emissions and immunity.

Model 15RH1 is a broadband gain reference antenna. It is primarily used in test chambers to accelerate gain measurements and minimize setup errors. Units can be supplied with a measured gain curve for enhanced gain accuracy over calculated values. Typical gain accuracy is better than ±0.3 dB over the band of operation. This unit is designed to meet NRL Report 4433.

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.

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. The Standard Gain Horn performance is very precise and predictable through design parameters.

High gain, low VSWR, input handling capability up to 300 watts CW, and rugged design make this horn antenna excellent for both immunity and emissions testing.
