Selecting a locationSelect a location for the transceiver that allows adequate aircirculation, free from extreme heat, cold, or vibrations, andaway from TV sets, TV antenna elements, radios and otherelectromagnetic sources. Antenna connectionFor radio communications, the antenna is of critical impor-tance, along with output power and sensitivity. Select an-tenna(s), such as a well-matched 50 Ω antenna, and feedline.1.5:1 or better of Voltage Standing Wave Ratio (VSWR) isrecommended for your desired band. Of course, the trans-mission line should be a coaxial cable.CAUTION: Protect your transceiver from lightning by usinga lightning arrestor.NOTE: There are many publications covering proper an-tennas and their installation. Check with your local dealerfor more information and recommendations.• Antenna location for mobile operationTo obtain maximum performance from the transceiver, selecta high-quality antenna and mount it in a good location. A non-radial antenna should be used when using a magnetic mount.ID-1To antennaRoof-mount antenna(Drill a hole or use a magnetic mount.)Gutter-mount antennaTrunk-mountantenna
