Keep the shipping cartons. A duplexer is separately required when only one antenna is used for both transmitting and receiving. Select a duplexer according to the transmitting and receiving frequencies. Ask your Dealer for details. For a description and a diagram of accessory equipment included with the IC-FR4000, see ‘Supplied accessories’ on p. ii of this manual. ■ Grounding ■ Selecting a location Select a location for the repeater that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electromagnetic sources. ■ Antenna connection 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, and feedline. 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for desired band. Of course, the transmission line should be a coaxial cable. CAUTION: Protect repeater from lightning by using a lightning arrestor. NOTE: There are many publications covering proper antennas and their installation. Check with your local dealer for more information and recommendations. To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the [GND] 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 [GND] terminal and ground as short as possible.
