[Antennas] 30 Meter Inverted Vee on 10M?

At 30MHz, the b/w will not be enough to cover down to 28.4 or so with a
decent SWR...not to mention there will significant lobes/nulls off the
antenna due to operating at a harmonic (though 3rd is not that bad).
Personally, I would use the newer antenna on 10 or a vertical or a 1/2wl
dipole for 10....cut the 40 for 17m and you can use that on 6.
