You don't need a trap. If you top load the vertical so
it is resonant on 160 as a current fed antenna, it will
also be resonant on 80 as a voltage fed antenna. You can band
switch at the ground. The advantage of this is that the
bandwidth will be wider, and you don't have to fool with
a trap. I am currently doing this with my 90 foot top loaded vertical.
