The SIM800L comes with two antennas for flexible installation:

• A wire antenna that can be soldered directly to the NET pin—ideal for compact and space-constrained designs.

• A PCB antenna with IPX pigtail connector, allowing the module to be enclosed in metal cases while maintaining excellent signal reception.

With its small size, low power consumption, and wide functionality, the SIM800L is a popular choice for GSM-based automation and communication systems.
