- I'm shunt feeding my tower for the low bands. When replacing air variables caps with fixed doorknobs, the reflected power is much greater. Any thoughts on the losses in doorknob caps vs frequency? Tk

- Someone else can tell you about losses, but I would expect that the stray inductance in the doorknobs would be much greater than with air variables. This, combined with the tolerance of the capacitor

- This problem could be caused by using a bypass type cap in a tuned circuit app. . There are two kinds of doorknob caps. . Bypass / coupling service and tuned circuit service. Typically, the largest

- Use LCC or their Brittish equivalents. ( Ask Ian G3SEK )They are made for tuned circuits and have been used for years in Swedish ship transmitters instead of variable condensers. Together with those

- No, is it not the other way around? I always believed " normal " variables to have a lot of self inductance? Together with the inductance of the connecting lead from anode to variable are part of par
