Thanks everyone

It will be mounted to the side rail of my Dodge 1500 4 door along with the
6 foot coliner for 2m and the 11 meter whip.
Yes it has a CB in it. I need the CB for talking to truckers when I go into
hurricane hit areas a day or two after the hurricane. Finding out what roads
are open, last place to get fuel etc...

Now all I need to figure out is how to keep the 10 meter and 11 meter
antennas from interacting too bad or place them in such a way that the
interaction does something that is usefull...
