You could use a complex trap like Butternut uses (which
would have higher efficiency with a coil, rather than a
distributed inductor like a linear loading stub), but I'd be
more inclined to just use a regular trap at the right
spot....maybe right below a capacitance hat.

Tom has a great idea! This would provide full performance on 80 and the best
performance from a 66' vertical on 160 meters. Automatic band switching and
great performance. Robert, If this sounds good I will be glad to calculate a
suitable trap/top hat for you. But if you still want the linear loading I will
calculate a suitable Butternut-style cap and linear loading that will do the
job.
