Anyone know of any type of antenna that would work better?


As long as you only cut it as much as needed to move it up into the
ten meter band it will still be a full length quarter wave antenna.
No, there is almost nothing you could get that is better..... provided
you mount it in the center of your roof.
Now, the interesting question becomes, "If you don't mount it in the
most optimum location, how much is it degraded, and would a loaded
antenna mounted in the center of your roof be any better?"

Realistically speaking, a center loaded (approximately 60 inch long)
antenna mounted on the trunk or roof is a very good compromise.
