Coaxial Cables (RF)

Choosing the right coax cable starts with understanding how construction affects performance. A cable’s copper core, dielectric, shielding, impedance, and connector type all directly influence signal loss, attenuation, and overall RF reliability. Traditional consumer formats like RG-59, RG-6, and RG-11 remain common, RG-59 for short runs, RG-6 for balanced broadband use, and RG-11 for long-distance, high-bandwidth or high-frequency applications. However, modern designs increasingly rely on smaller coax types (e.g., 1.13 mm, 1.32 mm, 1.37 mm micro-coax) for Wi-Fi antennas, cellular modems, Bluetooth modules, and GNSS/GPS receivers, where flexibility and compact size matter just as much as electrical performance.

In these compact RF systems, the right connector pairing is critical. Pre-assembled cables often use U.FL, IPEX, MMCX, SMA, RP-SMA, or QMA connectors to ensure proper impedance matching and minimal reflection losses at high frequencies. These assemblies are optimized for embedded radios, IoT devices, access points, and router upgrades offering low-profile routing while still maintaining controlled attenuation and shielding effectiveness across GHz bands.

Finished and pre-assembled coaxial cables simplify installation by providing factory-tested performance and correctly matched connectors, whether you’re installing an outdoor RG-11 feed, running standard RG-6 for TV/data, or connecting a compact U.FL-to-SMA jumper for a cellular or GPS module. When choosing a cable, consider run length, operating frequency, environment, connector compatibility, and how much signal loss your system can tolerate. These factors ensure you select the right solution, from flexible micro-coax jumpers for embedded antennas to rugged coax assemblies for long-range, high-power RF links.
