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
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
