end fed half wave antenna #56
Description
My end fed half wave antenna is a DC short given a transformer between antenna and radio. Pin 7 ( GPIO04 ) and GND pin see a DC short, measurements done before all is about to run, before power is turned on. The low pass filter between is not DC short. How should I deal with the DC short antenna and raspberry Pi? Should I add a capacitor in series with the signal path? What value? Where to add it?
