ALSR100 coaxial cable 30% better than RG174 cable: This 10 cm ~ 1000cm long SMA extension cable uses ALSR100 coaxial cable with double layer shielding + pure copper core, lower losses than RG174. While RG174 is a cable with simple shield and a single wire core, ALSR100 features tightly woven double layer shielding and high quality one-piece copper core.
