2 INSTALLATION AND CONNECTIONS2-2Select a location for the transceiver that allows ad-equate air circulation, free from extreme heat, cold,vibrations, away from TV sets, TV antenna elements,radios and other electromagnetic sources.The base of the transceiver has adjustable feet fordesktop use. Set the feet to one of two angles, to meetyour operating preference.Selecting a locationGroundingTo prevent electrical shock, television interference(TVI), broadcast interference (BCI) and other problems,ground the transceiver using the GROUND terminal onthe rear panel.For best results, connect a heaviest gauge wire or strapto a long ground rod. Make the distance between the[GND] terminal and ground as short as possible.R WARNING! NEVER connect the [GND] ter-minal to a gas or electric pipe, since the connectioncould cause an explosion or electric shock.Antenna connectionFor radio communications, the antenna is of critical im-portance, along with output power and receiver sensi-tivity. Select a well-matched 50 ø antenna and coaxialcable feedline. We recommend 1.5:1 or better of VoltageStanding Wave Ratio (VSWR) on your operating bands.The transmission line should be a coaxial cable.When using a single antenna (for the HF, 50/70 MHzbands), use the [ANT1] connector.CAUTION: Protect your transceiver from lightning byusing a lightning arrestor.30 mm10 mm (Tin)10 mm1–2 mmsolder solderTinCoupling ringPL-259 CONNECTOR INSTALLATION EXAMPLEqerwSlide the coupling ringdown.

When the SWR is higher than approximately2.0:1, the transceiver automatically reduces the TXpower to protect the final transistors. In that case, anantenna tuner is useful to match the transceiver andantenna. Low SWR allows full power for transmit-ting. The IC-7100 has an SWR meter to continuouslymonitor the antenna SWR.Slide in thedirection ofarrow.Controller bottom view |
