Dr OM Flam,
Not only does the tower affect your INV L, now you have
let us know of the 80m slopers and another 160m antenna.
These wire antennas have drastically more influence on
your INV L than you ever thought the tower would have.
In the end you may get a pretty good match with low
SWR on your INV L but your radiation pattern will be
so convoluted you'll never know where your signal is
