Hi all,
I have made a full wavelength square loop antenna for my FM radio (3m in length). My radio has a telescopic antenna which has just one connection to the PCB. I don't see any coupling capacitor on the line from antenna. I have found a 1N4148 here though. My problem is I don't know how to connect my external antenna to the PCB. I am thinking about connecting one end of the antenna to the PCB GND and then using a capacitor (picoFarad range - read this somewhere) between the other end of the antenna and my PCB antenna connection. Will this work. Any help is greatly appreciated.
