The Antenna: The antenna proper consists of a length of copper or copperweld wire, with a center feedpoint. Three popular lengths for the antenna are these: a. 130-140' (best, if you have the room and want the strongest results on 80 meters. b. 90-110' (works second best on 80 meters, with good results on all other bands).
