LMR®-400UF ULTRAFLEX (By the Foot or Spool)

The LMR®-400UF (Ultraflex) from Times Microwave Systems is a high-performance, ultra-flexible 50-ohm coaxial cable designed for demanding RF applications where repeated bending or tight routing is required. Available for purchase by the foot or in full spools of 500-ft on rigcables.com, this bulk cable features a stranded center conductor and durable TPE (thermoplastic elastomer) jacket, making it significantly more flexible than standard LMR-400 while maintaining excellent low-loss characteristics. With superior RF shielding (>90 dB) and weather-resistant construction, it's rated for both indoor and outdoor use, offering reliable performance in environments with high EMI or frequent movement.

Compared to traditional RG-8U and RG-213, LMR®-400UF delivers substantially lower signal attenuation—often half the loss at VHF/UHF frequencies—resulting in more power reaching the antenna and better overall efficiency. It provides a tighter bend radius, lighter weight, and enhanced flexibility without sacrificing durability, making it a modern upgrade over the older, more rigid designs of RG-8U and RG-213. Typical applications include **ham radio antenna feeders**, mobile installations, jumpers in wireless systems, GPS setups, WLAN/WISP links, SCADA, and any RF interconnect requiring flexibility, low loss, and reliability in tight spaces or dynamic setups.
