A 2.4G wireless SMA antenna is a type of antenna that is designed to transmit and receive radio frequency (RF) signals in the 2.4 GHz frequency band. The antenna is typically used with RF modules or transceivers, such as the NRF24L01, to provide wireless communication capabilities for devices such as sensors, remote controls, and other electronic devices.

The SMA connector is a type of coaxial connector that is commonly used for RF applications. The SMA connector has a small, screw-on connector that is suitable for use in compact devices and systems.

The gain of an antenna is a measure of its ability to direct or amplify the RF signals that it transmits or receives. An antenna with a gain of 2dB will generally have a stronger signal than an antenna with a lower gain, but it may also be larger and more directional.

To use a 2.4G wireless SMA antenna, you will need to connect the antenna to the RF module or transceiver using the SMA connector. You will also need to consider the orientation and placement of the antenna to optimize its performance. The antenna should be placed in a location where it has a clear line of sight to the device it is communicating with, and it should be oriented in the direction of the other device to maximize the signal strength.
