R Visually Inspect Coax/Connectors for any Slits or Damage
– moisture should not be allowed to penetrate
fittings or your coax.
R To maximize the life of your radio, it is important to understand antenna basics before transmitting on
your radio, transmitting without an antenna, or with high SWR (Standing Wave Ration)
– can void war-
ranty support.
R An Active SWR Meter is a great tool to have when selecting an antenna for your needs. You can monitor
and confirm that your SWR is within safe levels when setting up your radio for the first time (periodically
checking SWR and your antenna set-up is advised).
Antenna Requirements
Antenna SWR Rating : 1.5:1 or less (on the radio frequencies in use.)
Antenna Impedance : 50 ohm (use 50 ohm rated coax and coax connectors).
Antenna Grounding : Ensure the antenna is mounted with a grounding plane.
