Review on DHT Electronics 2pcs RF Coaxial Coax Adapter: SMA Male to BNC Male Connector - Improved Signal Quality and Versatile Compatibility by Michael Wilson

This little part seems to work well with my Ailunce Ham Radio handheld radio. This simplifies changing antennas. As far as I know the threads on the screw are only enough for so many uses. Using it saves threads and the need to replace them. Fast and easy to use. No problem. Didn't notice any performance degradation. Recommended. Note. This small element extends the length of your antenna. At first I didn't like the way he looked, but I was starting to get used to it. See image.
