You need to check with me ahead of time on this. These amps look like new and have been testedfor functionality.They area universal 2.4GHz amps and work with most 802.11, 802.11b, 802.11G equipment but check for your specific compatibility. This willgreatly extend the range of your link by boosting your radios output to+27dBm (500mw)

Note that the connectors arefemale N type connectors to connect between your radio and antenna. Green power led and red data transmit led. Unit sold as-is, as seen in photo.These Units are the same as the YDI branded power amps such as the YDI 2440. They come in 2 versions; a stand alone unit that is powered by a direct connected power supply or a 2 piece unit that includes a separatepower injector unit. In this scenario the amp unit would be mounted outside next to your antenna array for the best gain and least amount of noise and loss.
