Signal amps in Sprint Nextel Corporation Posted February 2, 2008 · Report reply Signals, max out, at some point. According to the numbers Sprint has given me for the Vision network. I'm not maxed out. I think an amp will help me. My problem is trees and hills. The trucker antenna improved my signal tremendously. A linear amp does wonders for CB radio's. I used one for years. Freq meter also. FCC regulates CB amps to 3 watts but, I know truckers who have 200w amps. When they get in areas where there is some CB radio traffic. The driver with the amp will walk on everyone else. Most CB radios come rated at 3w. But most full time drivers get their radios peaked out. A tech goes in and max's out the internal amp above what the fcc allows. This is fact. When peaking out a radio it needs to be done properly. There is a point where the quality of the signal deteriorates. Just turning up the amp full blast generally the signal will be just as bad if the signal is weak. Amps can improve the signal whether it be weak or strong. tuning the amp with a freq meter and adjusting the power are going to be tuned differently depending on the original signal. The point is frequency can be amplified, monitored and controlled. Its just a matter of having the right tools to manipulate the frequency. At this point the tools are more limited thhan CB's and hams. CB radios operate in Hz range, Ham radios operate in GHz and EVDO, Vision, The edge operate in MHz. If you look at Ham radios they have a boat load of controls, meters and amps.
