2 INSTALLATION AND CONNECTIONS s Grounding To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the linear amplifier through the GROUND terminal on the rear panel. For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distance between the GROUND terminal and ground as short as possible. R WARNING: NEVER connect the GROUND terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock. s Antenna For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select antenna(s), such as a well-matched 50 Ω antenna with more than 2 kW power rating, and feedline. 1.5:1 of Voltage Standing Wave Ratio (VSWR) is recommended for a desired band. Of course, the transmission line should be a coaxial cable. When using 1 antenna, use the [ANT1] connector. CAUTION: Protect your linear amplifier from light- ning by using a lightning arrestor. Antenna SWR Each antenna is tuned for a specified frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0:1, the linear amplifier's power drops to protect the final FET. In this case, an antenna tuner is useful to match the linear amplifier and antenna. Low SWR allows full power for transmitting even when using the antenna tuner. The IC-PW1 has an SWR meter to monitor the antenna SWR continuously.
