Buying Guide

Choose the right connector

Match connector types (RCA, BNC, UHF/PL259) to your devices — RCA and BNC are common for S/PDIF digital audio while UHF/PL259 is typical for radio/ham use

Prioritize impedance and shielding

Use 75-ohm coax designed for digital audio and look for multi-layer shielding to reduce interference and preserve S/PDIF signal integrity

Length vs. signal loss

Shorter runs reduce attenuation; for longer distances choose thicker conductor or higher-quality RG-series cable to maintain signal

Connector quality and termination

Solid, gold-plated or precision-machined RCA/BNC terminations and secure crimp/solder joints reduce contact resistance and dropouts

Installation needs and jacket rating

Select in-wall or installation-rated jackets for fixed runs and flexible jackets for patching; white or color options help match décor or rack labeling
