Please don't use all CAPS and also some paragraphs would make it easier to read.


Most mobile CB antennas aren't going to allow you to do 10/11 meters with a low SWR. If your SWR is 1.2 or so in the CB band it is almost guaranteed going to be over 2.0 when you go to 10 meters. You need an antenna tuner if you plan to use a CB antenna for both with a low SWR. Or you could install a 11 meter antenna on one side of the cab and a 10 meter on the other and use an antenna switch.


Do you have a ham radio license? If not then you shouldn't be in the 10 meter band anyway.
