I have a corbra LTD 29 classic and a willson 2k antena.

The directions for tunning say that the swr meter sould not be over 3. Well I moved the antena up and down its full travel and cannot get the swr below 3. What is the problem is it still to long?

Where and how did you mount the antenna? Did the instructions for the antenna have you cut the antenna?Did you put the ends on the coax? Have you checked the coax for continuity between center post the on pl-259 and the outer piece.

I made a braket out of stainless angle drilled a hole in it for a antena stud( came with 1 plastic washer or insulator, put the stud thru the hole put insulator ontop side of braket and put nut on (Looks like a coupling nut) then installed the antena. I talked to a tech from cobra and he says that the antena is grounded out, I am thinking the cb cable is the problem, I bought the cable from a truck stop for cb's but it must now be a good quility one. I have a ohm meter what do I neet to do to test the cable or check for continuity. what would the meter read?

Put the plastic washer on the other side

If you look at the top of the connector that you installed in the bracket you will see that around the stud is an insulator. The plastic washer will sit on top of your bracket, then the coupler nut that the antenna screws into. Unplug your coax from the antenna connector.Take your VOM and set it to OHMs. Check continuity between the bracket and the center stud. There should not be continuity there. The plastic washer should keep the stud from touching the bracket. On the bottom side of the bracket, check continuity between the threaded outer part of the connector and the bracket and there should be continuity. Test from the center port of the connector where the post on the PL-259 goes in to the bracket and again you should have no continuity. Check to make sure that your bracket is grounded. To check your coax, disconnect both ends from what they are connected to and check for continuity between the center post and the outside of the PL-259. I would agree that it sounds like your grounded out somewhere. These tests should tell you where.
