My tj has a factory hood ground strap from the ground below the cowl. So the hood should be a good ground.

Yep, same with roof racks, fenders, doors, tail gates, tire racks even bumpers. Anything that attaches to body MAY provide a less than ideal RF ground point.

I have never really noticed one, but have never really checked. I have an 01 and it maybe different.

seen them with and without... but you are correct it should have been a decent ground plane.

Okay so I received my 3' firestik antenna and tuned it. I get a SWR of 2.5 on channel 1 & channel 40 with a SWR of 1.4 on channel 20. I am going to stick with this setup and call it good because I cannot fit a 4' firestik in my garage.

You're still way to high. Let's investigate your cable. Have you tried a better quality cable? Have you checked all of your connections?

Good luck. They are low enough to work. Any issues will show eventually.

I have tried a better quality cable with no difference at all. I also checked all the connections and they all check out. I am an engineer so the testing is pretty straight forward for me. The only thing I can think is the length of the antenna, but 3' is as tall as I can go.

Wilson has several tuneable antennas that will fit your rig. Here is another idea, put a SWR meter in line between the radio and antenna and tune it that way.

When I tuned it I put the SWR between the antenna and radio. I think I will just call it good as it is below 3.0 and will not damage the radio.
