How RF Antenna Cables Work
RF cables transmit electromagnetic signals between:
- Antennas
- Readers
- Radios
- Amplifiers
- Communication equipment
The signal travels through:
Center Conductor
Carries the RF signal.
Dielectric Insulation
Maintains conductor separation.
Shielding Layer
Protects against electromagnetic interference.
Outer Jacket
Provides environmental protection.
A high-quality RF cable minimizes:
- Signal attenuation
- Electromagnetic interference
