Yep, one of the things that they did right on this radio was to use a regular SMA antenna connection that is found on most other radios on the market. One catch, though: The LED flashlight on the radio is a little close to the antenna, which means you have to be careful which antennas you choose. I put a Comet SMA503 on my UV-3R to test, which worked well.
1+ proper SMA
I had to file flat, the beveled flange surrounding the LED on mine. I had a bunch of HT antennas I was swapping around. That darned bevel makes some antennas bind and tilt.
Small negligible inconvenience.
