Model 3181 & Model 3184 End Fed Mini-Bicon Antenna User Manual
●The Model 3181/3184 is designed for surveillance, spectrum monitoring, and shielding tests.
●The frequency range for the Model 3181 is 500 MHz to 9 GHz and the frequency range for the Model 3184 is 1 GHz to 18 GHz. The Model 3181 performs best up to 9 GHz, but is usable to 18 GHz if amplification is used. The Model 3184 performs better than the Model 3181 in the 9 GHz to 18 GHz range. Data to 18 GHz is provided for both antennas.
●The radome provides weather protection for outdoor testing, and a weatherizing kit is included to protect the antenna connection.
●The radiation pattern is omni-directional in the H-plane, allowing the antenna to receive signals from every direction around the axis. The range covers most wireless bands worldwide, and is designed for the lowest possible VSWR across the range of operation. The antenna exhibits better than 2:1 VSWR for most of the range, and never exceeds 5:1 above 1 GHz.
●The small sizes of the antennas enable them to be used for amplifier harmonic measurements when performing tests per IEC 61000-4-3.
●Each antenna is calibrated during manufacturing. The results of the calibration are tabulated as gain and antenna factor vs. frequency for use in Specification Compliance Testing. Typical data is provided starting on page 26.
