When it comes to connecting an antenna with a PL259 connector to a Baofeng UV-5R radio, there are a few adapters you may need to consider. The Baofeng UV-5R radio utilizes a SMA-Female connector, whereas the PL259 connector is a UHF connector.
The most common adapter you’ll need is a PL-259 to SMA-Female adapter. This adapter will allow you to connect your PL259-terminated antenna to the SMA-Female connector on your Baofeng UV-5R. The adapter is a small, inexpensive piece of hardware that is easy to use, simply connect it to the PL259 connector of the antenna and then plug it into the SMA female connector of the radio.
Another adapter you may consider is a UHF SO-239 Female to SMA Male Adapter, this adapter allows you to use antennas with a UHF female connector on a Baofeng UV-5R which have a SMA-Female connector.
It’s important to note that there is also a UHF connector variant of Baofeng UV-5R radio, which comes with a UHF connector, so in that case no adapter is needed.
It’s also important to make sure the frequency range of the antenna match the radio. A wideband antenna will work with Baofeng UV-5R but a narrowband antenna may not, so check the frequency range before purchasing an antenna.
In summary, the most common adapter you’ll need when connecting an antenna with a PL259 connector to a Baofeng UV-5R radio is a PL-259 to SMA-Female adapter. This small and inexpensive piece of hardware allows you to connect your PL259-terminated antenna to the SMA-Female connector on your Baofeng UV-5R. Make sure you check the frequency range of the antenna and the connector type of your radio before purchasing the antenna and adapter.
