Coaxial Cable Rangeful SMA (male) to PL259 UHF (male), RG58/U, 50 Ω, 15 m

Rangeful 15 m coaxial cable with an SMA male connector at one end and a PL259 UHF male connector at the other provides a flexible 50 Ω RF link in a single assembly. Constructed with RG58/U dielectric and shielding, this cable is intended for short-run connections between devices that use SMA and UHF/PL259 interfaces. Its 15 metre length allows placement of transceivers, antennas, or test instruments with modest separation while maintaining the characteristic impedance required for reliable RF signal transmission.

Advantages

The cable delivers a consistent 50 Ω transmission path using RG58/U construction, helping to reduce reflections and impedance mismatch for typical VHF/UHF and HF applications. Its combination of SMA (male) and PL259 UHF (male) connectors enables direct connection between equipment with these commonly used RF ports without additional adapters. The 15 m length balances reach and signal attenuation for short to medium cable runs, and the flexible jacket facilitates routing in confined or temporary setups.

Suitable for

• Amateur radio transceiver connections where SMA-to-PL259 interface is required
• CB radio setups and short-run antenna feedlines
• Laboratory and field test arrangements linking instruments with SMA and UHF ports
• Temporary installations and RF troubleshooting where a flexible 50 Ω jumper is needed

Key specifications

• Cable type: RG58/U coaxial
• Impedance: 50 Ω
• Length: 15 m
• Connector A: SMA male
• Connector B: PL259 UHF male
• Construction: stranded center conductor with braided shielding and polymer dielectric
• Jacket: flexible PVC (suitable for indoor and temporary outdoor use)

How to use

Ensure both equipment connectors are clean and free of debris before connecting. Align the SMA male to the SMA-female or adapter and screw the PL259 onto a matching UHF-female socket until hand-tight; avoid excessive torque to prevent damage to connector threads. Route the cable to minimize sharp bends and avoid running parallel to power cables to reduce potential interference. For permanent outdoor installations consider additional protection; this cable is primarily intended for indoor and temporary deployments.

Usage recommendations

Check VSWR and insertion loss in your setup if using near the cable's length limits or at higher frequencies. Use cable ties or clamps with protective padding to secure the cable without compressing the jacket or braid. Replace the cable if connectors show wear, corrosion, or if performance measurements indicate increased loss or mismatch.
