dual band VHF/HAM antenna recomendations

Sorry for the delayed response I was over landing in central Idaho for the last week. I used the diamond K540 from expedition exchange. His price is better than most. You can find it here

I mounted it to the roof rack I built. It folds down nicely for trail use.
