A 2-Part Video Presentation about

Off-Center-Fed Dipole Antennas


Part-1 compares the OCFD to other multi-band antennas.  It covers theory about how the OCFD can work multi-bands without traps, etc. and then explains how to design an OCFD. 

Part-2 gives exact details on how to home-brew (d-i-y) an OCFD.

Common Mode Current

Its Effects on Antennas and Feedlines

 What is Common Mode Current (CMC) ?

  • How does it effect our antennas, transmission lines, and our neighbors?
  • What can we do to avoid/prevent CMC?
