The #1 Point of Confusion: SMA Connectors

Handheld radios use two different types of SMA connectors. They look similar, but they are opposites and are not compatible. Here is how to tell them apart.

Type 1: SMA-Male on RADIO (Needs SMA-Female Adapter)

This is the most common style, used by Baofeng, Quansheng, and some Retevis models. Look at your radio's antenna port: if you see a CENTER PIN, and it's flush to the radio, you have an SMA-Male radio.

  • Fits Radios: Baofeng UV-5R, Quansheng UV-K5, Retevis RT5R
  • You Need: An SMA-Female adapter (which has a center hole)

Type 2: SMA-Female on RADIO (Needs SMA-Male Adapter)

This is the "Japanese-style" standard. Look at your radio's antenna port: if you see a CENTER HOLE, that protrudes from the radio, you have an SMA-Female radio.

  • Fits Radios: Yaesu, Icom, Wouxun, TYT, Retevis RT85, Retevis RA89
  • You Need: An SMA-Male adapter (which has a center pin)

Other Common Connectors

  • SO-239 (UHF-Female): This is the standard, large "Mobile Ham / CB-style" socket found on all mobile and base antennas, SWR meters, and antenna mounts. It accepts a PL-259 plug.
  • BNC: This is the "twist-lock" connector most commonly found on handheld scanners and test equipment.
