1. Do not rack mount the UAD4 in this configu ration Serious loss of range and performance may occur Place the UADA with antennas in a location that is in direct view of the transmitters for best re sults OUTPUT Figure 5 1 2 Wave Antenna Mounting Antenna Placement for Optimum Range and Rack Mounting For maximum range and when rack mounting the antennas must be remotely located The ALP 450 comes complete with a variety of mounting hardware and 10 feet 3 meters of low loss coaxial cable A combination mounting bracket Model No AB 2 with 10 feet of coax ial cable is available for 1 2 wave antennas Antennas should be placed in a location with a clear signal path to the transmitter This path should be as short and free of obstructions as possible Obstructions such as walls ceilings and metal objects will reduce range and perfor mance Rack Mounting Insert the unit into a 19 rack enclosure and se cure with screws not supplied Rack Mounted Antenna Connectors Antenna cable connections may be made to the front of the rack mounted UAD4 by installing the adaptor cables supplied Proceed as follows Remove the plug knock outs from the front panel See Figure 6 Install the adaptor cables from the back side of the bracket Tighten the nut and lockwasher securely Attach the other end of the cables to the in puts of the UAD4 Tighten securely Front of rack antenna2.
