3125 Precision Dipole Antennas
Frequency Range: 440 MHz – 3010 MHz
Model 3125 Balanced Precision Dipole Antennas for electromagnetic field testing are an omni-directional emissions source for immunity testing and are designed with frequencies that match the operating frequencies of cellular phones and other wireless devices.
In typical use, a chosen dipole is substituted for a wireless device of the same frequency. The substituted dipole then allows the test to be performed with greater repeatability and lower measurement uncertainty. Applications include immunity testing of pacemakers, hearing aids and defibrillators.
The dipoles are tuned half-wave length resonant with a series-parallel coaxial stub balun. Each antenna has fixed length dipole elements mounted in a Teflon support block. The coaxial balun is terminated into a type “SMA” receptacle.
