Hello all
I'm planning a base station antenna at 5GHz with 8 culoms ,and i need to have a calibration port to calibrate the antenna.
the calibaration network is made from directional coupler and the isolation level
as to be -30dB.
Does anyone know why do i need to use the calibration network?
thanks in advance
