MX SMA Female To SMA Female Bulkhead Connector Chassis Mounting (MX-1726)

Any enclosure carrying RF equipment - a router, a wireless module, a telemetry radio - eventually needs its antenna connection to cross from inside the box to outside it, and drilling a cable straight through the wall is a weak, unsealed way to do that. This bulkhead connector solves it properly: it mounts through a single panel hole with a nut on the outside, presenting an SMA female port on both the inside and outside faces, so an internal pigtail connects to an external antenna cable through a clean, mechanically solid pass-through rather than a loose cable grommet. It's the right part for any build where RF equipment lives inside a sealed or semi-sealed enclosure and the antenna needs to be outside it.
