Overview

Mini GSM/Cellular Quad-Band Antenna - 2dBi SMA Plug is a slim external antenna designed for cellular and GSM/GPRS hardware that supports the 850/900/1800/1900/2100MHz bands. With 2dBi gain and 50Ω impedance, it is a practical choice for development boards, prototypes, and embedded wireless builds that need an external SMA antenna.

The antenna uses an SMA male connector, a common interface on many cellular development boards. It is well suited for quad-band GSM hardware and is highlighted as a compatible external antenna option for setups such as Adafruit FONA MiniGSM and SIM800-based projects that support an external antenna connection.

Important: if your board uses RP-SMA, you will need an adapter. If your module uses u.FL, a u.FL to SMA adapter cable is required. Also note that cellular modules like FONA need a host microcontroller over UART and do not operate as standalone devices.

Compatibility Notes

Item	Type	Description
SMA Port	Direct fit	Connects directly to boards and modems with an SMA antenna connector.
RP-SMA Port	Adapter required	An RP-SMA adapter is needed; this antenna does not directly mate with RP-SMA connectors.
u.FL Port	Adapter cable required	Use a u.FL to SMA adapter cable for modules such as external-antenna cellular boards with u.FL sockets.
Cellular Module Use	System note	Compatible with supported quad-band GSM hardware, but the cellular module still requires a microcontroller and valid network/SIM setup to function.
