BNCJ‑SMAP Low Profile Black SMA‑to‑BNC Adapter 50 Ω SMA Male to BNC Female RF Connector Adapter for HT Radios and Antennas

Simply the best BNC SMA adapter made. It's tight at first, but that's what makes it good. No slop or movement, great electrical connection and vastly superior to the other off name brands I've tried.

I did have to 3D print an adaptor for this to fit onto my Yaeusu Vx-5R, so if you are using it for that radio, know that the socket on the adapter is not deep enough for the rubber grommet to seat onto the radio. The male threaded screw post with the female SMA on the radio is very tall. Otherwise, this adaptor is great. A little stiff but after a few seat and reseats of an antennae, it works perfectly. Using with a Signal Stick.

Bought for my Yaesu. Great fit, fills up the gap between the connector and case of the radio.

These adapters are good quality. Will be buying at least 4 more. I appreciate the hard work that went into these.

I literally just ordered another one in SMA male/BNC configuration. The base that sits against the HT case is wide enough that you don't have to worry about breaking the connector because of an accidental bump or drop. Makes switching antennas a quick process. No issues with grabbing the wrong antenna. Then having to use a whimppie adapter that if you're lucky may break off.

Serves the purpose and is definitely lower profile. Fits the Yaesu FT-70DR perfectly.

Wanted to migrate to BNCs on my HTs. This unit works great on my Diamond antennas.

Can't go wrong with Diamond - I like the low profile, durability and excellent signal we get with these adapters. They've tolerated and performed in very cold icy to very humid and arid desert conditions year after year and still are reliable performers. With more poor quality adapters circulating than ever we appreciate these being consistent and tough.
