Note
The antenna has large impact on reception of the module, the best antenna wavelength is 1/4, and generally use 50Ohm single wire, the antenna length of 315M one is about 23cm.
Also the position of the antenna affect the reception of the module, keep the antenna stretched and away from the shield, high pressure, and interference source as far as possible.
