The base loading is made of a 4" diameter 40-turn coil of 10AWG copper with pitch set in three groups. 5 turns at 0.375", 30 turns at 0.250" and the remainder at 0.200" pitch. The tap is made with a copper aligator clip from the feed point bracket.
The variable capacitor is a two-section air variable with total capacitance of 40-650pF.
The antenna is slipped over the end of a 1" diameter oak rod fastened to the base. The antenna feed is removed by a bananna plug socket at the base so the unit can be "broken down" easier.
