The next modification will likely be finding a 10 M trap at a swap meet

Why not put a quarter wave stub for 10metres about half wave down from the
top to make it radiate as two half waves in phase on 10? That would also
guive a little loading on the more LF bands increasing efficency slightly.
I'm not sure without checking what the effect on the bands below 20 would be.
