Depends on what your SWR is, and having a good ground plane. I have no idea what type of antenna you have, but that window mounted one has to go. The twin antennas can be hard to get co-phased. Buy yourself an SWR meter and tune that magnetic mounted one. I would put the antenna about 3/4 of the way back on your cab . Shorten or lengthen your antenna, about a 1/4 " at a time until you obtain your lowest SWR reading. 1.1.1 is perfect, and anything over 2.0.1 will be hard on the radio.
If you don't already have a good antenna, a Wilson 1,000 magnetic roof mount is a darn good one.
Grounding your radio to the truck is also something you should be checking. Don't use the battery for the ground. Run the wire to the frame of the truck.
I like to use the seat belt bolt area. Remove the bolt and put your ground wire under it, then cinch it down.
Run the positive wire directly to the battery. Not the cigarette lighter, or some other accessory wire. You might pick up static that way. The battery is clean power.
