Coaxial Cable can have different impendances. For television antennas, but also inside SCART cables, the 75 Ohm cable is needed. Look for the proper type (see below) when using cable for these purposes.
| Type | Impedance | Purpose |
|---|---|---|
| RG-8 | 50 Ohm | Thick Ethernet |
| RG-58 | 50 Ohm | Thin Ethernet |
| RG-59 | 75 Ohm | (Home) audio/video signals (LF and HF) |
| RG-62 | 93 Ohm | IBM3270 Arcnet |
