Designed for robust RF signal transmission in critical applications, this LMR400-based RF jumper cable assembly combines the low-loss performance of LMR400 coaxial cable with industry-standard BNC Male and UHF PL-259 (PL259) Male connectors. Ideal for bridging RF equipment in broadcast antennas, base stations, test & measurement systems, and industrial automation, this assembly offers exceptional flexibility and durability. The solid copper center conductor ensures superior conductivity and power handling, while the LMR400 cable’s flexible foam polyethylene (FPE) dielectric maintains signal integrity across a wide frequency range.

Q1: Can this cable replace RG8 cables?
A: Yes. LMR400 offers similar specs to RG8 but with better flexibility and lower loss at higher frequencies.
Q2: Is outdoor exposure possible?
A: Yes, with weatherproof jackets (optional) or connector sealing. LMR400’s jacket resists UV and moisture.
Q3: What’s the maximum bend radius?
A: Avoid < 25x OD (dynamic) or < 50x OD (static) bends to prevent damage.
Q4: Are female connectors available?
A: Yes. Request custom assemblies with BNC Female/UHF Female connectors.
Avoid Over-Tightening: Use recommended torque for threaded connectors (BNC: 0.5–0.7 N·m).
Grounding: Connect shields to chassis ground to prevent EMI loops.
Route Protection: Use cable ties or conduit to prevent abrasion.
Store Coiled: Keep unused cables loosely coiled to maintain flexibility.
Note: Specifications subject to change. Always refer to product datasheet for critical applications.
