FIGURE 1 AMPLIFIER INSTALLATION Page 3
INSTALLATION Amplifier installation is illustrated in Figure 1. Mount the amplifier as close to the antenna as practical. Keep coaxial cable runs short, avoiding sharp bends and pinching. The antenna should be matched to an SWR better than 1.5:1 for best results. Higher SWR will degrade the performance of the amplifier. Mount the amplifier away from sources of heat, and where air can freely circulate around it.
FIGURE 2 DC CONNECTOR WIRING Attach DC input wires in accordance with this diagram. If the wires are too large for the holes, solder them to the sides of the blade. OPERATING PRECAUTIONS CAUTION: This amplifier produces RF voltages that can cause painful and dangerous RF burns. Use caution! Connect and disconnect all RF Connections iwth the DC power and drive power off. DRIVE POWER: RF power transistors, although quite rugged in most respects, are easily damaged by overdrive.
