Hi, Don
I would definitely favor the Inverted-L configuration to maintain the
high-current portion of the a antenna as a vertical radiator with the
current maximum distributed as high as possible.
Problem with a base loading coil is that the current maximum would be in the
loading coil that isn't much of a radiator. If you could add enough light
gauge wire to the top of your 80 m vertical to resonate it on 160, that
would be an entirely different matter and would probably work rather well
Good luck!

Subject: Topband: Vertical vs inverted L question/opinions
I am requesting opinions on what would work best for 160m based on a bottom
loaded vertical or inverted L.
I have in the past used and inverted L for 160m using a common feed with my
80m vertical. The 80m vertical has parallel wires for 40m and 20m also and
it works real well with 38 radials laid down in the grass. I like to
compare it to a fan dipole but only the vertical section is the multi wire
part as the radials are buried.
Anyway I am starting to plan for the winter season and I am wondering if a
loading coil on the bottom of the vertical would yield better results than
the inverted L. The L is limited to at best 50ft vertical section and the
rest on trees. My thoughts are if I use the 80m vertical section I will
have 68 ft of height which may be better than the L. The vertical is not
structurally strong enough to add a wire or a cap hat to the top of it.
Clearly I have the ability to try both and play around but I have time to
make alternate plans so I am fishing for opinions and or suggestions.
