GSM/GPRS Magnetic Base Antenna – SMA Male, 7dBi, 3m Cable
The GSM/GPRS Magnetic Base Antenna is an external omnidirectional antenna designed to improve wireless signal reception and transmission for compatible GSM, GPRS, and cellular communication modules.
Featuring an SMA male connector, a 3-meter RG174 coaxial cable, and a magnetic mounting base, this antenna provides a convenient solution for positioning an antenna away from electronic enclosures to improve signal reception.
It is suitable for GSM communication modules such as the SIM900A and SIM908, as well as other compatible cellular devices operating within the antenna's supported frequency bands.

Important: Confirm that the device supports the antenna's frequency bands and uses a standard SMA female connector. Some modules use U.FL/IPEX connectors and require a suitable adapter.
Connection Example – GSM Module
- Identify the GSM antenna connector on the communication module.
- Connect the antenna's SMA male connector to the matching SMA female connector.
- Position the antenna vertically for typical omnidirectional operation.
- Place the magnetic base on a suitable metal surface.
- Keep the antenna away from large sources of electrical interference.
- Check the GSM module's network signal strength after installation.

Important Notes
- This is a passive antenna and does not generate or amplify signals electronically.
- Actual antenna performance depends on frequency, installation position, cable losses, and surrounding conditions.
- The advertised 7dBi gain and VSWR values have not been independently verified.
- SIM900A modules typically use 900/1800MHz GSM networks; check local network availability before use.
- The antenna does not automatically provide 3G, 4G, or 5G compatibility.
- For SIM908 modules, connect to the cellular antenna port rather than the GPS antenna port.
- Avoid sharp bends or damage to the coaxial cable.
- Verify connector compatibility before installation.
