Multi Band Modification
Use a BNC socket and plug your tuning capacitor into it. That way you can have
20, 17, 15, 12, 10 and 11 meter coax capacitor ready to simply plug in for each band.
The same number of turns applies for any band from 10 to 40M the length of RG58/U coax
capacitor tunes the frequency match for each frequency, so 2 and 11 turns. For
10M the coax capacitor ends up around 100mm long, very short.
