Don't overlook traps. My low band antenna is a double (fan?) dipole with
80 M traps in one leg for 160/80 and 40 M traps in the other leg for 60/40
coverage. It seems to work fine at about 55 feet.
In an inverted V configuration, just install the legs at 90 degrees to each
other for minimal interaction. I did this for a 40/80 double V which also
worked great with the top at 40 feet.
73, Charlie k3ICH
