A view
                      of the coupling enclosure on the assembled
                      antenna. The 3 position slide switch selects 6, 8
                      or 10 turns of the primary winding on the ferrite
                      toroid core. SWR was 1:1 or better at resonance.
                      Best match occurred with the 6 turn tap on 28 MHz,
                      the 8 turn tap on 18, 21 and 24 MHz and the full
                      10 turns on 14 MHz.
