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.
