[TowerTalk] 80 Meter trap design needed

[Mark - N5OT]

I hope to make a trap vertical that works on 80 and 160.  I hope to find 
an 80 meter trap design that can handle full power.  The 80 meter energy 
would stop when it gets to the trap, but the trap would pass 160 meter 
energy.

It won't be suspended with wire so smallness and lightweightness are not 
necessary criteria.  I hope someone can just shoot me a design and 
values.  Everything I find searching the internet is less 
straightforward than "make a coil like this and stick a capacitor of 
this value here" which I would think would be the easiest way forward.

Any advice?
