A firm, semi-rigid small extension cable is a great way to mount directional antennas to goggle receiver modules or to stand-alone receivers. The cable will bend however you like, then stay where you put it.
The antenna side of the extension is SMA,
The receiver/transmitter side of the extension is either SMA or RP-SMA, depending on your selection above. SMA has the center pin, while RP-SMA has a center hole.
