cb in truck need some help regarding setup

Are you in the UK? I've never seen one of those radios before although I'm sure it would work just fine without the amplifier.
Most of your performance will come from the antenna system so what type of vehicle is it going into?

 

Time for an upgrade, Go with a stryker 94hpc for space and available options.

 

With a decent antenna system that tiny radio should reach 20-30 miles to my receiver and maybe 10 or so to the average person. Nothing wrong with that radio.

 

If it were mine I would use the radio and see what happens. Much of successful radio operation is determined by who is around to receive and respond to you on available frequencies. If there are compatible radios within reach being used, then it can be great. But if not, then the story is very different.

As noted, the antenna is very important. Generally, the longer and higher the tuned antenna is, the better for radio operations. If you want to communicate to greater distance, a taller and higher antenna is often the key to success.

Have you tried your radio setup yet? What happened?

 

Your antenna will work best at a single frequency and performance will taper down the further you get from that frequency. Choose that frequency wisely based on usage in your area.
