Antenna amplifier with compact design for use anywhere, easy to install. Thanks to the amplifier incorporating 500mW radio coverage is extended by 325% compared with a similar antenna without an amplifier. The antenna consists of 3 parts joined together: the SMA-Male-Inverted (RSMA-M), the central body or amplifier and antenna. RSMA connector can be oriented with an angle of 0 degrees to 90 degrees to the axis of the antenna, which allows easy connection and guidance on access points, peripheral cards or WI-FI that have this connector (the common). Supplied with power supply that plugs into the amplifier (6VDC @ 600mA). Transmitting in the band of 2400-2500 MHz with what is compatible with IEEE 802.11-b/g. Transmitting antenna gain of 12dBi and 15dBi to reception. Operational mode and bi-directional signal type TDD DSSS/FHSS. Size 82x22x20mm device.
