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
