Key Product Information

​​Single Lobe Radiation Pattern

The model 3117 maintains a single main lobe pattern in the direction of the horn axis over its frequency range. This characteristic is essential for even distribution of electromagnetic energy on a target surface, and accurate measurement of gain and vector information. The model 3117’s unique design suppresses the propagation of high order modes. The result is an antenna with a well-defined single lobe radiation pattern that outperforms other antennas in its class.

Ultra Broadband

The model 3117 sweeps from 1 GHz to 18 GHz without stopping for band breaks, making it ideal for automated testing. It has the widest usable frequency range of any antenna in its class, with no performance degradation from high order modes.

Power Input

The model 3117 uses a Type N connector and accepts up to 300 watts of continuous input power with up to 500 watts of peak power. The antenna’s high gain and low VSWR over its operating frequency translates into efficient amplifier use and high field strengths.

Uniform Gain, Low VSWR

This antenna has a more uniform gain and antenna factor because of the better behavior of its radiation pattern. Since the pattern is stable over frequency, the gain and the AF also remain stable. Similar antennas of this class exhibit large variations of the gain and the AF as the frequency increases.
