Yeah lots of things, ground straps between the antenna mount to the door, the door to the cab, and the cab to chassis. Others can give you details.

Also good coax, from the antenna to the radio, not cheap truck stop junk.

 

Search button or scroll through the CB section on here. Lots of reading material.

 

Grounding straps produces the rf ground or balance that is needed to bring up the radiation efficiency of the antenna system.

The antenna system requires two parts of the signal to be transmitted, one is a positive wave and the other is negative or opposite wave,

It has to have a balance to work right - I just simplified the explanation.

The grounding straps are there to make sure the rf ground is covered with enough of a radiating element for the opposite or negative wave.

 

Ridge is giving you some good advice. But the first thing I would do is buy a longer antenna. A 6 inch antenna isn't going to work very good on 27 mhz, I don't care what fancy name it has. Ha.
