I solved my mounting problem with a rugged ridge light bar . Made from two inch pipe with a flat plate welded across the top that is 5 inches wide and 46 inches long . A little expensive for an antenna mount , but I wanted a light bar any way . I looks good and works great . Right now I have a 5/8 wave hustler mounted on it and don't have any trouble hitting repeaters 40 to 60 miles away . I plan on rep[lacing the 5/8 antenna with my comet CSB-790A this week-end if the wx co-operates .
Here are a couple of pics of mine .

I also plan to mount my little tarheel II on the lower part of the light bar soon .
