On my 601HD I mounted my VOR antenna on the bottom of the rear
fuselage just forward of the tailwheel (about 1' from the end if you
have a trike). Seems to work although I use the GPS 99.9% of the time
anyways...

Exactly the same here. It gets the same or better reception than any other
plane I have flown. The added benefit is (since the top of the tail isn't as
high as my wife's Cessna) you won't take your eye out during a preflight.
