Michael, the screwdriver antennas (most of them, anyway) work quite well.
I would suggest you pick up a copy of "40+5 Years of Mobileering" by Don
Johnson W6AAQ. Don is the guy that designed the original screwdriver, and
he can (and will) sell you one of his, or tell you which of his competitors'
antennas work well, if at all.

After years of single band mobiling I've decided to invest in a
screwdriver
antenna. There seem to be 3 of 4 main manufacturers that make these
types.
I would be glad of anyone's experience with these antennas.
Thanks
