The Double Bazooka Antenna
www.w1npp.orgThis is definitely not the antenna for the ham 2 It is of course possible to use a balun at the antenna if the direct coupling to the outside of the feed line causes " antenna " currents to flow on the line. With most random lengths of line these currents should be fairly small in a 3.5-Mc. system. — Editor. 1.5 3.5 3.7 3.8 FREQUENCY-MC. 4.0

A more elegant solution is to use a BALUN transformer, with either 1:1 or 4:1 impedance transformation (depending on the line type). 6 Connecting to Coaxial Inputs Most high-end an d middle market receivers today are equipped with coaxial
