3127 Magnetic Dipole Antenna
Frequency Range: 440 MHz – 2665 MHz
All Model 3127 Magnetic Dipole Antenna resonant loops are designed with better than +/- 0.1 dB symmetry (0.2 dB peak-to-null) in at least a +/- 5 MHz band around the labelled centre frequency. VSWR is less than 5:1 at the resonant frequency, which is slightly higher than the labelled symmetry frequency. For reference purposes, gain and symmetry values are provided for a 200-300 MHz band (depending on model) centered about the labelled frequency. The loops have a nominal 50. impedance, a maximum continuous transmit power of one watt, and are equipped with a female SMA connector.
The loops are calibrated using an A2LA accredited process with a typical measurement uncertainty on the order of +/- 1.0 dB at the centre frequency. During the calibration process, the dipoles are also certified to meet the +/- 0.1 dB symmetry required for use in the ripple test specified in the CTIA’s Over-The-Air Performance Test Plan, in a +/- 5 MHz band around the labelled centre frequency. Maximum ripple, VSWR, and approximate gain values are provided with each calibration.
