  • Fits Kenwood TK-208, TK-240, TK-250 and TK-260 models

Two-Pack SMA to UHF Adapter Cables

This pair of one-metre coaxial jumpers connects a handheld radio with an SMA female port to an antenna or accessory fitted with a UHF SO239 female connector. Both ends present a 50 ohm interface using RG58 cable, so the link suits amateur and commercial two-way radio setups. The twin pack provides a spare lead for field work or a second rig.

Low-Loss 50 Ohm Signal Path

RG58 construction maintains a consistent 50 ohm impedance across the one-metre run, keeping insertion loss minimal for typical VHF and UHF handheld power levels. The SMA female and UHF SO239 female connectors mate securely without adapters, so there are no extra junctions to degrade the signal. No active components means silent operation and zero power draw.

Stable Performance During Extended Transmissions

The dielectric and braid are rated for continuous duty at the power levels common to the listed Kenwood, Baofeng and Wouxun models, so the cable does not heat up during long nets or repeater contacts. Connector shells remain firmly seated even when the radio is clipped to a belt and the antenna flexes. The second cable in the pack allows quick changeover if a connector is damaged in the field.

Questions about this item

How do I connect the SMA Female end to my Baofeng UV-5R, and which step do people often get wrong?

Screw the SMA Female connector onto the radio's SMA Male antenna port until finger-tight; the common mistake is cross-threading the fine threads by forcing it.

What maintenance or replacement will the RG58 coaxial cables need over time?

Inspect the RG58 jackets for cracks or water ingress and check the SMA and UHF SO239 pins for corrosion; replace cables if shielding is damaged or connectors loosen.

What is the first limit that appears when using these 50 Ohm cables for extended transmissions?

The 1 metre RG58 run introduces measurable insertion loss on longer key-downs, so sustained high-power use will heat the cable and increase SWR first.
