This page provides a Twin Wire Line Calculator.
EXAMPLE:
- INPUTS:
- Dielectric constant (εr) = 2.4
- Permeability constant (μr) = 1
- Spacing between conductors (‘s’) = 15 meters
- Diameter of conductor (d) = 5
- OUTPUTS:
- L (H/m) = 7.05e-7
- C (F/m) = 3.78e-11
- Z (Ω) = 136.45
Twin Wire Line Equation
A twin wire line is typically a flat, parallel, and balanced type of transmission line. It’s a common choice, especially in the VHF frequency range. The wires are usually encased in a plastic ribbon made of polyethylene, making them both strong and flexible.
The spacing between the two conductors is carefully maintained to minimize RF radiation.
