|I worked out the information myself, as I received no replies.
Length of spokes on Capacitor Hat :
80 Meter 48 inches
40 Meter 38 inches
30 Meter 23.5 inches
20 Meter 10 inches

I have been having trouble tuning the 20 Meter and other bands on the AV-680 Hygain antenna.
My "guess" is that the tuning lengths in the AV-640 manual for the capacitance hat are the same for the AV-680.
Has anyone tried the tuning step ? The initial length for 20 Meters is 14.5 inches as shown on the diagram and the length in the AV-640 is about 10 inches.

I have a Drake 2-B and a copy of the owners manual. However, I do not quite understand the operation and adjustment of the passband tuning.
How do I set the passband knob pointer ? I can rotate the knob 360 degree's and I do feel a slight "detent" at one position.
