Hoping to clear up some confusion on end-fed wires, half-wave or random and the impedance transformers used with them. You also get a free rant on contests and a quick glimpse of my new Elecraft K1. Check out the Half-Wave End-Fed antenna group on Facebook, by Steve Ellington. Formulas for half-wave wire calculations are 143/f in MHz for meters and 468/f for feet. Feedback would be appreciated especially to correct any mistakes I may have made in my analysis. Version Française en cours d'édition...
