I haven't modeled a 160M Inverted L in a long time, but my recollection is
that when you use one on the higher bands the radiation pattern is a lot
different than what you might expect. I'm not saying it won't work on the
higher bands, but I don't believe you will get a lot of the low-angle
radiation that you would normally want for DX purposes.

Why would you want *another* inverted-L? Make the first one bigger, and use
it on both bands. Obviously, avoid 1/2WL or 1WL or 1.5WL or any integer of
1/2WL -- too hard to match. The classic 160m inverted-L is 165' long, or
~3/8WL on 1.8 MHz, and works splendidly as a 3/4WL on 80. Can't see the
advantage of having two inverted-Ls......-WB2WIK/6
