If you keep the power down to 100 watts, I'd recommend the SGC SG-237. It'll tune a 102-inch whip from 75M thru 6M. It will also work with any radio - not restricted to a particular brand/model.
If you are using it with an Icom and want it to work with the Icom tune button, take a look at my web page at http://www.ham-kits.com
for information on an interface that will do that.
