About Antenna SWR Value
The TG-UV2 Plus radio is designed with tri-band, UHF(470mhz to 520mhz), VHF (136mhz to 174mhz) and Police band (350mhz to 390mhz), that is why the SWR value is lower, it's reasonable, and actually it does not affect the function, maybe nothing is perfect in the world, some customers keep buying this radio even though they complaint about the antenna SWR value, overall it's a superior radio.
One more thing, if you don't need the third band of police band, actually you can get an extra antenna with only dual band, which will be much better.
