USB WiFi Antenna Mod Answered
I am working on adding a helical antenna to a cheap USB WiFi adapter. My question is where do I connect the antenna to existing circuit. I've attached a closeup picture with three likely points. My three main questions are:
1) Where to connect the external antenna
2) Do I disconnect the rest of the onboard antenna (my gut says yes) or just add in the new
3) What impedance will the external antenna need to match? I assume the components between points C&B and B&A are for some kind of impedance matching.
