Topband: 160m L and 80m Vertical

[MR TREVOR DUNNE]

Hi All

I need some help in trying to get an antenna that will cover both 80 and 160,

What I was planning is a Inverted L with a 75 ft Vertical section of Aluminum tube and the rest tied off to a convenient tree, what I would like to add is a 80m vertical wire spaced off the main aluminum element of the L,

Would this work and what sort of spacing would I need, could I feed both on the same feedline ???

Thanks
Trevor
