well, a 12 foot telescoping whip would be plenty to make a half wave on 6, 
which wouldn't require a ground plain.
If you have a way of measuring, you could extend the whip out to a half wave 
on six and it should present a decent SWR and resonate not too badly.
a bit clunky for an HT, but doable I guess.
