At the very minimum you should have the SWR tuned on it. It's not hard to do especially if you have a cb shop near you or a truck stop. You can do it yourself if you buy an SWR meter from radio shack. What kind of antenna is it? K40? Wilson? It should be tunable either by cutting or adjusting. Once your SWR is tuned you will notice a huge difference.

i have the same CB only with a 36in firestick i havent had a bit of problems with it. but my dad has that cb also and a 48in (not sure of the brand) fiberglass whip on his dodge... after he installed it he could barley pick me up less the 5 miles away with it.. he took it down to the cb shop and they did something internaly to it but they said his bigest problem is that he had coiled the extra wire instead of figure 8ing it. but i instead of buying the pre cut 10, 20 or 25 ft coax cable for it, just bought the length of coax ( RG58 i think) and then picked up the correct ends for the cable and crimped them my self so i dont have extra wire that can cause any problems.

On mine, I ran dedicated power and ground wires from the battery (fused of course) and ran that pair or wires, twisted to reduce interference, back to the radio where I also installed a power line filter. Radio is nice and quiet even with the engine running. Some tips below:
