LMR® standard is one of UV Resistant Polyethylene jacketed cables with 20-year outdoor usage time period. LMR400UF offer much better flexibility in comparison to corrugated and air-dielectric hard line cables.
Rather flexible outer conductor allows the smallest bend radius possible for any similar cable in terms of size and performance. Note that LMR400 is more stiff than LMR400UF (UltraFlex) due to its solid center conductor.
In comparison to semi rigid hard-line cables LMR400 has quite similar loss while sporting much better loss characteristics among other flexible cables.
The multi-layered outer foil conductor is rated approximately at > 90 dB. RF Shielding is 50 dB.
A wide range of common interface types connectors can be used with LMR-400 cable. LMR400UF (UltraFlex) has a stranded center conductor and rubber outer jacket designed to endure multiple bending Cycles
These cables are great for replacing air-dielectric type cables such as RG-8 when low loss RF cable is required. Applications include mobile antennas, WLAN, GPS, and many others.
