Remark
VCC voltage module operating voltage and good power filtering;
A great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, generally a 50 ohm single-core wire, the length of the antenna 315M approximately 23cm
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.
