  • 50 ohm impedance matches standard RF equipment
  • RG58 construction handles high-power signals
  • Nickel-plated bodies resist corrosion
  • Gold-plated brass contacts ensure reliable conductivity

Cable type and intended use

This 50 ft RG58 coaxial cable connects an SMA male plug to a TNC male plug. It is built for RF paths that require a 50 ohm characteristic impedance. The nickel plated connector bodies and gold plated brass contacts suit installers who need a ready made link for antennas, radios or test equipment.

Behaviour on long runs

RG58 construction with copper conductors and soldered inner joints keeps loss predictable over the full 50 ft length. The shielded design resists external noise so the signal stays clean in high powered applications. Attenuation rises steadily with frequency but remains consistent because the dielectric and braid are uniform along the whole run.

Installation notes and common issues

The cable arrives terminated so no crimping or soldering is required on site. Route it with gentle bends to avoid kinking the solid dielectric. The most frequent problem is cross threading the TNC coupling nut if it is forced; start it by hand and tighten only until the mating faces seat firmly.

Questions about this item

How much heat or signal loss should I expect from the 50 ft RG58 cable during continuous use?

The 50 ohm RG58 construction with soldered copper conductors minimises loss and keeps heat negligible for typical RF applications.

What equipment must already have SMA and TNC ports for this cable to connect directly?

You need a device with an SMA female jack and another with a TNC female jack; the nickel-plated connector bodies mate with those standard interfaces.

Will the gold-plated brass contacts on this cable mate reliably with older brass or nickel connectors I already own?

Yes, gold-plated brass contacts resist corrosion and maintain low resistance when mated with legacy brass or nickel RF connectors.
