Working Principle of HLF LMR Cable
HLF LMR cable works on the principle of controlled electromagnetic signal transmission through a coaxial structure. It consists of a central conductor, dielectric insulation, shielding layer, and outer jacket.
- The inner conductor carries the RF signal.
- The dielectric layer maintains spacing and ensures consistent impedance (typically 50Ω).
- The outer conductor (shielding) prevents signal leakage and blocks external interference (EMI/RFI).
- The outer jacket protects the cable from environmental damage.
This design allows the cable to minimize signal loss (attenuation) while maintaining high-frequency performance, making it ideal for telecom and wireless systems.
