In RF design, cables rarely get much attention. Antenna placement gets discussed. Radios get compared. Firmware timing becomes a debate. But the short cable between them? That part usually shows up late in the design. Often it’s just described as “a short jumper.” In many systems that jumper turns out to be RG316 coaxial cable. You’ll find it inside wireless gateways, GNSS receivers, telemetry radios, and RF test setups. It’s thin, flexible, and easy to route through crowded enclosures. Because of that, engineers reach for RG316 almost automatically when a short RF connection is needed.

In many RF projects, the cable is the last thing engineers think about. Design meetings revolve around radios, antennas, modulation schemes, and firmware timing. When something fails in the field, the first suspects are almost always the same: firmware bugs, antenna placement, or environmental interference.

Most RF systems do not fail because of antennas. And surprisingly, they rarely fail because of radios either. More often, the quiet component between them becomes the problem. That component is the RF coaxial cable. At first glance, a coax cable seems simple. It connects two RF ports. If the connectors mate and the signal passes, everything appears fine. Engineers usually move on to more interesting parts of the system.
