SG-235 Smartuner - SGC

SG-235 ManualUse jumpers around metal backstay triangles on split backstay antennas.Corrosion may cause up to several hundred ohms of resistance to occur eventhough you may think that a metal-to-metal connection would be a good one.6.5 Antenna Coupler MountingThe coupler is mounted using the proper mounting ears on the case. Choose alocation immediately adjacent to the antenna feed point. In trunk mountedmobile installations, it is very important that the tuner is located so that theantenna insulator is within a few centimeters of the antenna exit hole. Notealso that the antenna lead must pass through an insulated bushing. High voltageconnecting cable must be used. (RG-8U cable with solid insulation may beused if the outer shielding is removed). A protective housing is highly recommendedwhen the coupler is installed on the outside, or on the deck.6.6 Antenna ConnectionThe antenna lead is connected to the high voltage insulator. During operation,use two wrenches when tightening the nut to prevent the stud rotating. Apotential of several thousand volts may be present at the antenna terminal andadequate protection must be made against accidental contact. It is also necessarythat the antenna is spaced at least 3 centimeters from the conducting surface.Sharp points in the lead-in wire should be avoided to prevent corona discharges.SGC Inc.
