Times Microwave LMR240 Cable Assembly with SMA male and SMA female connectors. LMR-240 Coax is the same size as RG-8x or Mini-8 cable, about 1/4 inch in diameter. Although it is just a bit larger than LMR-195, LMR240 offers a significantly larger center conductor and supports better signal retention for longer cable runs and higher frequency use. LMR-240 is an excellent cable for runs up to 25-30 feet in WiFi and Cellular use, and provides superior performance for HF/UHF/VHF installation up to 150 feet. The PE jacket used on LMR-240 makes it tougher and able to stand abrasion. It also makes it a bit less flexible than similar sized RG Type coax.
