Simple choke balun
Usually I use a simple choke with antennas made with aluminium and a transmission line balun with ratio 1:1 or 4:1 for wire antennas

Balun and Transformer Core Selection
I mainly use 73 material for receiving applications in low power applications between .1 and 30 MHz
Putting a Balun and a Tuner Together
Use a balun to connect from the twinlead to an unbalanced tuner
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
Programs for balun
Baluns are very complicated with poor designs giving very poor results. If you have some knowledge, this program will assist you in designing rf transformers and antenna baluns and unun
