Putting a balun and tuner together commercial antenna tuners use unbalanced circuits such a Pi-, T-, or L-network to match unbalanced loads to 50 ohms for our transmitters. A simple way to include the capability to handle balanced loads is to include a balun somewhere in the circuit, PDF file

Quarter Wave Line Matching Transformer This page allows you to calculate the impedance required for a 1/4 wave (electrical) section of line. To calculate the electrical length of the line you need to multiply the velocity factor of the line (available from the supplier of the line) by the free space length of 1/4 wave
