1.0 Introduction The ETS-Lindgren Model 3126C Series Sleeve Dipole antennas are omnidirectional, having an electric dipole pattern approaching that of a half wave resonant dipole. The sleeve dipole design allows the antenna to be end fed to avoid cable and feed point See the ETS-Lindgren interactions that interfere with the performance of the antenna.
2.0 Maintenance Cleaning Maintenance of the Model 3126 is limited to external components such as cables or ETS-Lindgren may connectors. substitute a similar part or new part number with If the 3126C requires cleaning, use a clean soft cloth moistened with water. Do not use any the same functionality for harsh or abrasive chemicals;...
3.0 Specifications Performance Specifications Model Range Pass/Fail Criteria 3126C-3500 3 GHz to 4 GHz a) Symmetry < 0.2dB through entire Calibration Range b) Max VSWR is 1.75:1 through entire band. 3126C-4500 4 GHz to 5 GHz c) Gain for 3126C-3500 must be greater than 1.0 3126C-6500 6 GHz to 7.2 GHz MHz at center frequency.
4.0 Mounting The Model 3126C Series Sleeve Dipole Antenna must be mounted to a support at the connector end of the antenna. An ETS-Lindgren mounting kit is recommended to support the antenna. 3126C antennas are Under no circumstances should any mounting structure extend inward more than 1.5 inches precision measurement (38 mm) past the connector end of the antenna.

5.0 Operation It is recommended that a 10 dB pad/attenuator be used at the input end of the Model 3126C Series Sleeve Dipole to minimize standing waves on the transmit cable. This is especially important for frequencies where the input VSWR is greater than 1.2:1. Before placing into The electric field of the antenna is polarized parallel to the antenna axis.
