First, my primary antennas for 80 and 40 have been a pair of 80/40 fans 
at right angles to each other. They are approximately horizontal, the 
approximate part being sag in the middle. The two wires are spaced about 
14 inches, using short pieces of 1/2-in PVC conduit with holes drilled 
in them for the wires to pass through.

60M may not play well in an 80/40 fan.

I've never tried a fan hung as an inverted vee -- I have plenty of 
organic supports, and a flat dipole is superior to the inv vee config. I 
don't see any reason why an 80/40 fan wouldn't work as an inverted vee.
