YDI AMP2440 Installation And Operation Manual
                 | |
1. DescriptionThe AMP2440 is a bi-directional amplifier designed for extending the range of 2.4 GHzwireless radio modems, Wireless LAN cards, Access Points and wireless bridges. Theunits provide transmit power amplification as well as receive signal gain. The amplifier isinstalled right at the antenna’s feed point, providing maximum effectiveness of transmitpower. This has the effect of compensating for signal loss in the transmitter cable to theantenna. Likewise, the Low Noise Amplifier (LNA) in the AMP2440 boosts the receivesignal right at the antenna prior to experiencing the loss in the transmission cable to theradio. This gain completely overcomes the losses in the transmission cable between theamplifier and the radio. This results in the lowest possible system Noise Figure. In fact,use of the amp will actually increase the receiver sensitivity by a few dB! The ultimateresult is the best receiver sensitivity and maximum possible range for whatever antennais used.The amplifier box is weatherproof and can be bolted to the antenna mast or tower legusing the U-bolt included. When properly installed, the connectors face down so thatgravity will drain all water away from the amplifier enclosure. This will prevent waterfrom settling on the face of the unit. The LEDs will also be facing downward so that theycan be checked for operation from the bottom of the mast or tower.DC Power to the amplifier is supplied through the transmission cable that carries the RF(Radio Frequency) signal. This DC voltage is put on the coax cable using the DC PowerInjector included in the amplifier kit. Both the amplifier and the DC Injector also containtheir own integral lightning protection as well as DC surge protection. No externalantenna lightning protection on the coax cable is required. (The DC Injector has agrounding stud to facilitate an easy connection to a good earth ground.) It also hasmounting flanges to facilitate permanent installation to a bulkhead or wall. If mounted to agrounded metal plate, then no extra wiring needs to be attached to the grounding stud.The amplifier box will provide maximum lightning protection when it is bolted to a groundedmast or tower. No extra ground straps need to be connected to the amplifier case.2.
