Hello,
I am new to the group. Recently got a Z3815A (module type) and was looking
at ZL1BPU's User Guide. Don't ask me why but before I soldered a BNC coax
to the bottom antenna pads I checked them with an ohmmeter and found 2.5K
across the signal pad and ground. I was surprised since there
Which type of ohmmeter have you used? What voltage does it use to make the
measure? What polarity? If the voltage is greater than 700mV and the
positive was put on ground maybe some diode has turned on... anyway 2.5K on
5V is 2mA. I have never made such a test on a GPS receiver. I can try on a
Well, the TBolt measures 1086OHM on the antenna connector with a test
voltage of 3V (2K range on the multimeter) and open circuit when switching
to 20K range with 800mV test voltage, positive on antenna and negative on
GND. The Motorola M12 has 1940OHM (2K) and open on 20K. The uBlox LEA-5T is
