2. E 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 Q antenna and feedline 1 5 1 or better of Voltage Standing Wave Ratio VSWR is recommended for your desired band Of course the transmission line should be a coaxial cable A CAUTION Protect your transceiver from j lightning by using a lightning arrestor PL 259 CONNECTOR INSTALLATION EXAMPLE Slide the coupling ring down Strip the cable jacket and soft solder Coupling ring 10 mm soft solder 10MM soft Strip the cable as M solder shown at left Soft na solder the center 1 2 mm conductor solder solder Slide the connector ee EIA body on and solder it Screw the coupling oT fab ring onto the connector body 1 2 mm 46 in 30mm in 10 mm in 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 transceivers power drops to protect the final transistor In this case an antenna tuner is useful to match the transceiver and antenna Low SWR allows full power for transmitting even when using the antenna tuner The IC 718 has an SWR meter to monitor the antenna SWR continuously 3 INSTALLATION AND CONNECTIONS E Required connections e Front panel MICROPHONES p 55
