The Model ATH18G27-1 is a wide band, low gain, wide beamwidth, high power microwave horn antenna. With a minimum gain of 8.8dB over isotropic, the Model ATH18G27-1 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

Cobham Sensor Systems’ Standard Gain and Broad Band Horn Antennas series provide superior performance for use in a wide variety of laboratory, commercial and military applications. With excellent input VSWR, these antennas provide high gain across the frequency range and consistent pattern performance. They have become a laboratory standard as a reference horn in anechoic chambers and outdoor ranges.
Sensor Systems horn antennas offer broadband performance in compact, lightweight form. Sensor Systems current horn antenna portfolio includes products operating from 100 MHz to 96 GHz for various applications with linear, circular, dual linear, and simultaneous circular polarizations.
Series Frequency Range: 4 GHz to 26.5 GHz. The ETS-Lindgren Model 3163 Series Conical Horns are high gain (Over 16 dBi) antennas, designed for use as feeds in tapered anechoic chambers, as well as in applications requiring high gain and linear polarization.

AR offers a complete variety of rugged, high-power antennas for virtually any testing procedures. Since all are frequency and power matched to AR amplifiers, it is easy to select exactly the right unit.

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.

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 Model ATH4G8 is a wide band, high gain, microwave horn antenna that provides a minimum gain of 11.5dB over isotropic. The Model ATH4G8 supplies the constant high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.
