Model AMP2440

Description

Front view of the AMP2440The Model AMP2440 is a waterproof bi-directional pole mounted amplifier for use with 2.4 GHz Spread Spectrum radio modems and wireless LAN equipment. Consisting of a low noise receiver pre-amplifier and transmit power amplifier, the AMP2440 offers significant increases in operating range and performance. The unit is ideal for use with YDI's Model 2400 digital radio modem as well as other 2.4 GHz Frequency Hopping or Direct Sequence Spread Spectrum radio modems and digital transceivers. When used with our Model 2400 and 24 dB gain grid dish antennas, ranges up to 50 miles (80 km) line-of-sight can be achieved!

The remote mounting capability allows it to be located right next to the antenna which places the full transmit power where it is most effective.

The receiver pre-amp boosts the received signal at the antenna. The latest low-noise amplifier (LNA) technology is used, improving the receiver sensitivity by several dB! This gain also compensates for the cable loss from the amp to the radio modem. Using the AMP2440 allows for the use of inexpensive transmission cable up to 200 feet between the radio modem and the pole mounted amp!

The amp is powered through the antenna transmission cable using the DC Power Injector which is located indoor near the radio modem. No separate power cable is needed for the amp on the mast.
