  18. Resonant/centered on 6.95 MHz (40m), 14.240 MHz (20m), 21.360 MHz (15m), 28.500 MHz (10m), 50.125 MHz (6m).
  19. SWR is under 1.5:1 on 20m, 15m, and 10m.
  20. SWR is between 1.5:1 and 2:1 on 40m/7-7.2MHz (R is low) and 6m (R is high).
  21. This is the compromise of moving the feed point offset to 40% to gain 15m band.
  22. More favorable matches can be obtained using a 33% offset at the loss of 15m band coverage.
