Default 80m/160m trap dipole

Hello All,
I have an 80m dipole that I wish to use on 160m as well. I am
considering using traps on the existing dipole. I have searched the
web and have not found any 80m/160m trap dipoles. Has anyone added
traps to their 80m dipole to make it usable on 160m? Or could anyone
point me in the right direction towards homebrewing traps to suit. I
have made traps in the past for 40m/80m dipoles but I am unsure what
dimensions, length, turns etc I would need for homebrewing a trap to
make my 80m dipole useable on 80m and 160m.
Thank You. Cheers Max


It is not clear to me whether you are talking about:

1. Increasing the length of your dipole to ~246 feet
and adding 80m traps or

2. "Making your" existing ~123 foot "80m dipole usable
on 160m" by adding 160m loading coils.
