Het Balun project
254/5000 Especially if you are a QRP member, the loss or return of a balun is important. You always want to make a connection with the lowest possible transmission power. It is a shame if the balun converts a large part of the supplied power into heat!

RF Baluns
This method will increase the antenna feed impedance by four so with a 50 ohm feeder it is suitable for driving 200 ohm impedance antennas, such as folded dipoles
