How to make a 13.56MHz antenna

1. cut a 80cm length small wire(Enameled wire, QiBaoXian in Chinese).

2. strip the skin a little and connect to the TP3 and TP4.

3. wire 3 rings, about 8cm in diameter.

This kind of antenna work perfect and easy to make, the voltage is about 12v or more.

why 80cm?

why 3 rings and 8cm?

I have this antenna, it works. But it is not good enough for eavesdropping.
May be another configuration will be better?
