SLM156 provides two antenna pins, which are MAIN_ ANT, GNSS_ ANT.
It is recommended that you use a 50Ω impedance antenna that matches the RF connector of the
module.
It is suggested that you chose RF adapter carefully on application end. It is necessary to select the
smallest possible loss of the RF adapter, and the recommended RF adapters are as follows:
 TD-LTE<1.5dB
 FDD LTE<1.5dB
