3161 Octave Horn Antenna

3161 Octave Horn Antenna

Frequency Range: 1 GHz – 8 GHz Model 3161 Octave Horn Antennas cover a bandwidth of 1 to 8 GHz. All models in the series are linearly polarized, have medium gain, optimum half power beam width (equal in both horizontal and vertical planes), and low VSWR. Antenna factors are constant throughout the entire operating frequency range. Comparisons of measured versus computed gain have been found to be within +/- 0.5 dB. ANSI C63.4 recommends the use of standard gain horn antennas as a reference standard above 1 GHz. Model 3161 Octave Horns have a constant antenna factor across their entire operating frequency, eliminating look-up in multiple charts to calculate measurements. Above 1 GHz, the antennas can be used as a reference standard per ANSI C63.4. While the coaxial feed allows power input of up to 550 W Model 3161, higher power input is possible by removing the detachable feed and direct mounting the flange to an amplifier waveguide port.
