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
warranty support.
An Accurate 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). You will need to use an SWR meter
designed for the UHF band. Other meters will NOT read correctly. Another option is an “Antenna
Analyzer”. With those you can sweep the entire UHF band and find the “sweet spot” or resonant point
of your antenna. Use this information to tune for the LOWEST SWR or lowest reflected power reading.
