Bi-directional amplifier that operates in the 2.4GHz band, ideal for applications based on wireless 802.11-b/g. Ideal to compensate for the loss of power radiated by the cables long distances to have more scope, or other uses. Made of metal to be installed indoors and protected from electrical shock caused by external factors. It consists basically of two elements: 6 VDC power supply and amplifier for indoor use. The amplifier has an input from the wireless network equipment and an output that goes to the antenna and amplifying the signals sent and received. The amplifier has two connectors to pass through, one is RSMA-H and the other SMA-F (50 Ohm). Also includes hose 20cm RSMA SMA-M-M. Transmission gain of 30dBm (max. adjusted automatically.) Output power of 1000 mW. Receive gain of 12dB (typical). Compatible with wireless networks compliant 802.11-b/g. Antenna not included.
