If a dipole is necessary for 80 would a balanced stub (1/4 wave on 80,
shorted at the far end) across the dipole insulator be the best method of
switching between a dipole on 80 and a loop on the higher frequencies?

I'm wondering if an 80m trap would work - high impedance
on 80m - relatively low impedance on the higher frequencies.
