1INSTALLATIONANTENNA CONNECTIONAn antenna system consists of an antenna, feed line,and ground. The transceiver can give excellentresults if the antenna system and its installation aregiven careful attention. Use a properly adjusted 50Ωantenna of good quality, a high-quality 50Ω coaxialcable, and first-quality connectors. All connectionsmust be clean and tight.After making the connections, match the impedanceof the coaxial cable and antenna so that the SWR is1.5:1 or less. High SWR will cause the transmitoutput to drop and may lead to radio frequencyinterference to consumer products such as stereoreceivers and televisions. You may even interferewith your own transceiver. Reports that your signal isdistorted could indicate that your antenna system isnot efficiently radiating the transceiver’s power.Connect your primary HF/ 50 MHz antenna feed lineto ANT 1 on the rear of the transceiver. If you areusing two HF/ 50 MHz antennas, connect thesecondary antenna to ANT 2. Connect VHF(144 MHz), UHF (430/ 440 MHz), and 1.2 GHz(TS-2000/ TS-B2000 Optional) antennas to theirrespective antenna connectors on the rear of thetransceiver. Refer to page 13 for the location of theantenna connectors.uTransmitting without connecting an antenna or othermatched load may damage the transceiver. Alwaysconnect the antenna to the transceiver before transmitting.uAll fixed stations should be equipped with a lightningarrester to reduce the risk of fire, electric shock, andtransceiver damage.Note: The transceiver’s protection circuit will activate when the SWRis greater than 2.5:1; however, do not rely on protection tocompensate for a poorly functioning antenna system.Connect all accessories to the transceiver {pages 3, 94}.Accessories include the following:• Microphone• Antenna Tuner• CW Key• Computer• TNC/ MultimodeCommunications ProcessorInstall and connect an antenna system{page 1}.Install a ground system that satisfies DCand RF grounding requirements {page 1}.Install lightning protection to protect theantenna system, your personal safety,and your property {page 1}.Install and connect a DC power supply {page 2}.• Headphones• External Speaker• RTTY Equipment• Linear Amplifier• Remote PanelGROUND CONNECTIONAt the minimum, a good DC ground is required toprevent such dangers as electric shock. For superiorcommunications results, a good RF ground isrequired, against which the antenna system canoperate. Both of these conditions can be met byproviding a good earth ground for your station. Buryone or more ground rods or a large copper plateunder the ground, then connect this to the transceiverGND terminal. Use heavy gauge wire or a copperstrap, cut as short as possible, for this connection.Do not use a gas pipe, an electrical conduit, or aplastic water pipe as a ground.LIGHTNING PROTECTIONEven in areas where lightning storms are lesscommon, there are usually a limited number ofstorms each year. Consider carefully how to protectyour equipment and home from lightning. Theinstallation of a lightning arrestor is a start, but thereis more that you can do. For example, terminate yourantenna system transmission lines at an entry panelthat you install outside your home. Ground this entrypanel to a good outside ground, then connect theappropriate feed lines between the entry panel andyour transceiver. When a lightning storm occurs,disconnecting the feed lines from your transceiver willensure added protection.
