2. ELECTRICAL CHARACTERISTICS
| Parameter | Typical Value | Note |
|---|---|---|
| Characteristic Impedance | 50 Ω | Standard for RG8; ideal for RF and power use |
| Capacitance | ~26.4 pF/ft (~86.6 pF/m) | Lower capacitance for efficient signal transfer |
| Velocity of Propagation | 66–80% (depending on dielectric) | Foamed PE offers higher velocity |
| Attenuation @100 MHz | ~2.2 dB/100 ft (~7.2 dB/100m) | Low signal loss |
| Maximum Operating Voltage | 1,900 V RMS | Suitable for high-voltage RF environments |
| Frequency Range | DC – 1 GHz or higher | Effective in RF/microwave ranges |
