Option #1- if the vertical element is in the clear - would be the best
choice. If you could extend the wire to 128' this would be better. If you are
stuck with 115' (30' vertical and 85' horizontal) let the remaining horizontal
length of 13' hand down vertically. (30' vertical - 85' horizontal and 13'
vertical - total length 128')
Option #1 fed as you described and using your current radial system (you may
have to install at least (1) radial for 160m and (1) radial for 80m. You
wont know until you try to tune the antenna for 160m and 80m. If you experience
difficulty tuning then install radials for those bands. By the way when
cutting radials use .15 wave length not .25. (ref. ON4UN - Low band DXing).
Have fun
