This LMR-240 antenna cable has an SMA male connector on one end and an SMA male connector on the other.  It is typically used to connect RF and GPS wireless infrastructures, such as antennas, amplifiers, routers and access points.

LMR-240® coaxial cable provides excellent performance, but yet is under 0.25 inch in diameter. It is the same size as RG-8X, but with better specifications.  Because of its solid center conductor, it is rather stiff.
