Manufacturer description
The Superbat SO-239 to SMA adapter cable 2-pack connects a handheld radio's SMA port to antennas and coax that use UHF (PL-259) connectors. You get two 6-inch (15cm) jumpers. One runs from a UHF SO-239 female to an SMA male, and the other runs from a UHF SO-239 female to an SMA female. Between them, you're covered whichever SMA gender your walkie talkie's antenna port uses. Both cables use 50 Ohm RG316 coax, which matches the standard impedance of amateur and CB radio gear. The cable is thin and flexible, so a mag-mount or base-station antenna lead can reach your handheld without a rigid…

Frequently Asked Questions
Will this adapter cable work with my Baofeng UV-5R?
The listing names Baofeng handhelds. The pack includes an SO-239 to SMA male cable and an SO-239 to SMA female cable, so check your radio's antenna port and use the cable that mates with it.
What is the difference between the two cables in the pack?
Cable A has a UHF SO-239 female on one end and an SMA male on the other. Cable B has a UHF SO-239 female on one end and an SMA female on the other. Both are 6 inches (15cm) long.
What impedance and cable type does it use?
Both cables use RG316 coax with 50 Ohm impedance, which is the standard for amateur radio, CB and scanner antenna systems.
Can I connect a PL-259 mobile or base antenna to my handheld with this?
Yes. The SO-239 female end accepts a PL-259 plug from standard coax or an antenna lead, and the SMA end connects to the handheld's antenna port.
How much transmit power can these cables handle?
The listing doesn't state a power rating. Check with Superbat or the product listing before running high-power transmitters through these RG316 jumpers.
