Mobile Signal Booster Coaxial Cable

1. Inner conductor — carries the RF signal (often copper, sometimes copper-clad steel).

2. Dielectric insulator — surrounds the inner conductor, keeps it centered and isolates it electrically.

3. Outer conductor / shield — usually a metal braid ± foil. Provides shielding from electromagnetic interference, also serves as the return path.

4. Outer jacket / sheath — protective outer layer (PVC, PE, sometimes UV‑resistant, weather‑proof, or LSZH, etc.).

Important electrical specs:

• Impedance — Commonly 50 ohm or 75 ohm. Booster systems/components are designed for one or the other; mixing them leads to signal loss or mismatc

• Attenuation / signal loss — The longer the cable, the more loss. Also increases with frequency. Choice of cable type, thickness, shielding, dielectric quality all affect loss

• Shielding effectiveness — How well the outer conductor blocks external RF noise, and prevents leakage from the cable. High‑quality shields help especially when the coax must run near power lines or other electromagnetic sources.

• Connector types / quality — The ends of coax need suitable connectors (e.g., SMA, N‑Type, F‑Type, etc.). The connectors must match the impedance and connector type required by the booster/antenna. Poor/loose connectors degrade performance.
