    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 .

    That looks good. I was going to suggest the A pillar with a light bracket as mentioned before, and a Comet dual band made for motorcycles.

    I may have missed it if someone already suggested this, but I just replaced one of the windshield bumpers on the hood with an NMO mount. Nice ground plane and not much chance of hitting something. I used an Austin 500c antenna, so it just folds over when the hood is full open.

    Does anyone have concerns about RF when mounting the antenna near the A pillar?

    A fellow ham mentioned that at 50W I'm exposing my brain to a lot of energy. My antenna is mounted to the windshield hinge, with an L bracket. I get great signal reports and hit all the repeaters.

    I just don't want to cook my brain anymore. I did enough of that as a young adult.

    I'd say yes but it's on the edge of what I would worry about. If you want... you can do the math yourself.

    So question I have always wondered about. (If this needs its own post Moderator please feel free to move it or let me know so I can.)

    Is there any reason why one should NOT mount NMOs to the engine hood of a vehicle? I have a 3rd gen 4runner and have been running it with a NMO clamp on type mount on the engine hood. It gives me no issues at all. Just curious why I should't drill the hole and mount that way. Looks like you Jeep guys could do it as well.

    Thanks!

    Besides defacing your vehicle, there is no electrical reason why you couldn't mount an antenna on the hood.

    Drilling a hole into the body of your vehicle, especially when that panel is expensive, seems like a terrible idea...but then again I don't own a jeep!

    Drilling a hole is no issue. When done right an NMO is waterproof and weather proof and will not rust. I have done several on other vehicals with no issue. I just was wondering why I should not do it on the engine hood. Seems like there is no issue other than running wires between the fire insulation and the hood itself (i.e. keeping it away from the hot engine.)

    @ WB9YZU, I know this is a dirt old post, but was wondering if you had any info on your carrier, thats exactly what I am looking for for hauling my kayak without having to go the whole cage rack way on my TJ. I tried searching "Best top carrier system" and other variations but cant find anything on the best top site like it. Thanks for any help!

    Hi Tracy, It appears Bestop stopped making them.

    The next best thing is a rack that mounts at the windshied hinges and back by the tail light.
