Here are some comments from Michael (KB9VBR):

The K4QCD Dually is two antennas wrapped up into one package. On one side you have an End Fed Half Wave with a 49:1 transformer. Flip it over and on the other side is an End Fed Random Wire antenna with a 9:1 transformer. The dual transformer concept is the best of both worlds. Out in the field you can go either way with the type of antenna you wish to deploy, the only difference is the length of wire that you hook up to it.
