		  I am wondering if I could just bend the one I have I have to meet 

the clearance needed for a belly mount.


	


    The pictures I see for this antenna appear to show

    a painted antenna rod. Is this a solid metal rod

    or is it some kind of conductor stuck inside a fiberglas

    sheath?

I am not sure if its metal or not. I am not near the plane and was wondering if anyone knew. I was trying to get my gameplan down before I go back to the hangar an hour away. This also got me to thinking... I was looking at the DIY CB antenna and I was thinking this might be the best route for me if I could bend it. Will mounting it on the belly and bending it back cause problems?

    Bending the antenna has very little effect on performance.

    The "business section" of a vertical antenna is in the

    bottom 1/3rd or so, bending the upper 2/3rds has the effect

    of electrically lengthening or lowering it's resonant frequency

    but even that effect is minimal.

Thanks Bob for the info.



I checked Radio Shack and found this CB mount.

It looks like the one in your DIY article. If my thinking is correct, I could use this mount and this antenna:



http://www.radioshack.com/product/index.jsp?productId=2102428



And cut it down to the 22" that you mention in the article, mount it with a ground plane to the belly of the plane and bend the top 2/3's back for clearance.



What do you think?

    I think you have a useful command of the simple

    ideas behind a solution of your antenna problem.

    You're cleared for 'take-off'.
