The Model AMP2440-I is a bi-directional amplifier for use with 2.4 GHz Spread Spectrum radio modem and wireless LAN equipment. Consisting of a low noise receiver pre-amplifier and transmit power amplifier, the AMP2440-I offers significant increases in operating range and performance. The unit is ideal for use with 2.4 GHz Frequency Hopping or Direct Sequence Spread Spectrum radio modems and Wireless LAN devices.

Simply insert this unit between your antenna and radio, and you will see an immediate gain of 12-16 dbi on both send and receive power levels. The amps have an integral 12 volt DC power socket and separate power supply and are intended for use within an enclosure or indoors. They can also be used outdoors with some silicon to seal the 12 volt power connector.

For installations where the cable loss from the amplifier to the antenna is more than a few dB, you should use the 2 piece version of this amplifier. (Amp 2440)

This version of the amplifier is ideal for use in any application where the total cable length from the radio coax to the antenna is short, but amplification is needed.

Applications

• Mobile installations where 12VDC battery voltage is available.
• Installations where the radio and the amplifier are both mounted in a weatherproof outdoor enclosure located near the antenna.
• Indoor installations where some extra gain is needed but the outdoor pole mounted amplifier is not practical.
• Installations where the antenna cable is short and the amp is protected from the weather.
