3126 Precision Sleeve Dipole
Product Image

ETS-Lindgren's 3126 Series of Precision Reference Sleeve Dipoles are truly omnidirectional antennas, having an electric dipole pattern approaching that of a half-wave resonant dipole, with typical gains between 1.5 and 2.0 dB.

Key Features
  • Meets CTIA +/- 0.1 dB Symmetry Requirement
  • Precision Gain for Range Calibration
  • Range of Frequencies to Cover Wireless Device Bands

ETS-Lindgren's 3126 Series of Precision Reference Sleeve Dipoles are true omnidirectional antennas, having an electric dipole pattern approaching that of a half-wave resonant dipole, with typical gains between 1.5 and 2.0 dB. The sleeve dipole design allows the antenna to be end-fed to avoid cable and feedpoint interactions that interfere with the performance of the antenna. Integral quarter wave chokes and/or ferrite loading (depending on frequency range) also help to reduce cable interaction. This design also provides exceptional symmetry (typically better than +/- 0.1 dB (0.2 dB peak-to-null) to meet or exceed CTIA criteria for ripple test antennas.

All 3126 Series Dipoles are 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 band (depending on model) centered about the labeled frequency. This dipole has a typical VSWR <3: 1 across this entire band, and may be used for precision range calibrations across the entire band provided appropriate padding (~ 10 dB) is used to minimize possible standing wave effects on cables. The dipoles have a nominal 50 impedance, a maximum continuous transmit power of one watt, and are equipped with a female SMA connector.

The dipoles are calibrated using an A2LA accredited process with a typical measurement uncertainty on the order of +/- 0.2 dB. Gain, VSWR, max. ripple, and measurement uncertainty values are provided with each calibration.
