RG6 vs RG59: Which Coaxial Cable for CCTV & Satellite?

1. Spec Table

2. CCTV: How to Choose + Power Core

For CCTV we have RG6+2C and RG59+2C: the +2C means with 2x power cores.
- <50m: RG59+2C with 0.5mm² power is enough, cheaper.
- 50-150m: RG6+2C with 0.75mm² power.
- >150m: Use RG6+2C with 1.0mm² or separate power supply.
Formula: For 12V 1A camera, voltage drop = current x resistance. If drop >2V, camera restarts at night.

3. Satellite TV

Satellite must use RG6 75ohm, double shield (foil + 64 braid). RG59 loss too big, signal mosaic. Our RG6 is 75ohm ±3, return loss >20dB.
