Hi PeterN
I found this old D1 Mini Pro in my junk box. I wanted an external antenna so it fit the bill. The ceramic ant. had been removed, which back in the day was an option vs removing the resistor. I tried several antennas, and low and behold, the RC aircraft antenna worked as good as any! (according to Vistumbler)
Thanks
Zim
The signal strength seems to be sufficient for your purposes or distance ... but at the moment there is obviously NO antenna connected to the output of the ESP8266, because the bridge would still have to establish the connection to the center contact of the antenna socket. At the moment there is certainly only a weak capacitive coupling, which also explains why your connected external antennas could not generate any serious differences.
Have a look here:
