Sleeve Dipole Antenna - ETS
Contents
1. vi www ets lindgren com 1 0 Introduction The ETS Lindgren Model 3126 Series Sleeve Dipole is designed as precision gain references for antenna range calibration and to meet the Cellular Telecommunication and Internet Association CTIA 0 1 dB symmetry requirement for ripple test measurements These antennas are truly omni directional having an electric dipole pattern approaching that of a half wave resonant dipole with typical gains between 1 5 dB and 2 0 cB Model 3126 2450 The sleeve dipole design allows the antenna to be end fed to avoid cable and feed point interactions that interfere with the performance of the antenna Integral quarter wave chokes and or ferrite loading depending on frequency range also helps to reduce cable interaction This design also provides exceptional symmetry better than 0 1 dB 0 2 dB peak to null to meet or exceed CTIA criteria for ripple test antennas 7 Introduction www ets lindgren com The higher frequency antennas include a radome and are characterized with the radome in place The radome provides improved dielectric properties for superior high frequency performance Radome Do not remove Do not remove the radome for any reason Weed Model 3126 3600 Each Model 3126 is designed with a VSWR less than 1 2 1 in at least a 10 MHz band around the labeled center frequency Gain values and 0 1 dB symmetry certification are provided for a 200 MHz to 300 MHz b2.
