ALSR240 is a 50-ohm low-loss RF coaxial cable and a cost-effective alternative to LMR240. It adopts FPE foam polyethylene dielectric, aluminum foil combined with tinned copper double shielding. It delivers stable impedance, low signal attenuation and strong EMI resistance, commonly used for antenna feeders, 4G/5G base stations, Wi-Fi coverage, GNSS, RFID and other wireless communication systems. With the expansion of global wireless infrastructure, the demand for ALSR240 cable and pre-assembled jumper assemblies keeps increasing. Below is the list of top 10 global ALSR240 suppliers, in no particular order.
