Coaxial cable Rangeful SMA male to SMA male RG58/U 50 Ω, 0.3 m

Coaxial cable Rangeful SMA male to SMA male RG58/U 50 Ω, 0.3 m is a short RF interconnect designed for reliable signal transmission between devices with SMA ports. The cable uses RG58/U construction with a nominal 50-ohm impedance and SMA male connectors on both ends, providing a compact solution for connecting antennas, radios, and test equipment in lab and field environments where a low-loss, short-length link is required.

Advantages

The cable combines standard RG58/U coaxial characteristics with SMA male terminations to deliver consistent impedance matching and minimal insertion loss over short distances. Its flexible jacket and compact length reduce clutter in bench setups and tight installations while the precision SMA connectors ensure a secure mechanical and electrical connection. The short 0.3 m length minimizes signal attenuation and reflections compared with longer patch leads.

Suitable for

• Connecting antennas to RF transceivers with SMA ports
• Linking radios, modems, or signal generators to measurement instruments
• Short-range laboratory and test bench interconnects
• Compact installations inside enclosures or test fixtures

Key specifications

• Coaxial type: RG58/U
• Connector type: SMA male — SMA male
• Impedance: 50 Ω
• Length: 0.3 m
• Typical use: RF signal transmission for antennas, radios, and test equipment
• Construction features: flexible jacket and standard coaxial shielding

How to use

Align each SMA male connector with the corresponding SMA female jack on your devices and screw the connector onto the port by hand until finger-tight; avoid over-tightening to prevent damage to connector threads. Route the cable to avoid sharp bends or kinks that can impair RF performance. For measurement tasks, ensure connectors and ports are clean and free of debris before making the connection to maintain low insertion loss and accurate results.

Usage recommendations

Use this 0.3 m SMA–SMA RG58/U cable for short, direct RF links where minimal loss and compact routing are priorities. For permanent outdoor antenna installations or applications requiring higher power handling or lower loss at higher frequencies, consider cables with larger diameters or different dielectric materials. Periodically inspect connector integrity and replace the cable if shielding or connector performance degrades.
