An external antenna: 25cm ordinary multi-core or single-core line
Pinout from left ? right: (DATA; VCC; GND)

Remark:
VCC voltage module operating voltage and good power filtering;
Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor, the length of the antenna 433M of about 17cm;
Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
