I am installing a HF mobile set up in my 88" dodge caravan.  I am using what is called a side mount, looks like this http://www.firestik.com/Catalog/M-2.htm on the lift gate of the van.  The mount came with RG-58 A/U coax with a spade connector on the copper braid and a ring terminal on the center conductor.  I am using hamsticks as the antennas

I have grounded everything in the van exhaust pipe, etc.  I hooked up the ring terminal on the coax to the big stud on the antenna mount, and the spade conntector on the little stud on the mount.

I put on a 20meter ham stick and hooked up an swr meter to the radio.  I am getting off the scale SWR readings all over the band.  same with the other hamsticks i am using.  What am I doing wrong?

It's hard to say what could be wrong until we take out a few variables.

Did you preset the adjustable whip length?  This should get you close.

Did you verify your cables into a known load?  Could be a a bad cable or connector.

Is the non-insulated terminal of the antenna mount really grounded?  You said you mounted it to the lift gate, but not where on the lift gate.  Also, be aware that a lot of times hinges aren't the greatest ground connections.  You may need to run a ground braid from the hatch to the chassis.

This gives you a few things to check out, check back in with your findings and we can go from there.

Ends up that the feed line that came with it is defective.  No wonder I couldn't get the SWR's down.  Thanks
