I only mentioned it because 3dB is a very significant change. By theory with unpainted mast you could talk 10 miles. Every 3dB takes twice the power to produce. Say you have 100 watts output, if you can pick up 3dB gain from the antenna it will talk like you have 200 watts. Conversely if you have 200 watts and you loose 3dB in the antenna it will only produce the effect of 100 watts.

Your welcome.
Also check with any really high end car stereo shops. Most stereo shops will not have a use for an oscilloscope, but some shops will use them.
Thinking about it and I am not sure if this will even work. You can try another antenna placed at least 37 feet away from your truck, with a power/SWR meter on backwards. You will need a ground plane or Dipole antenna and something at the other end of the meter, maybe a florescent bulb.
Distance is critical. CB broadcast over the 11 meter band and takes roughly 37 feet for a full wave to form, which is why it sounds garbled when your next to someone transmitting. The oscilloscope should show the amplitude, but amplitude is also voltage when it's traveling in conductor, so a power meter or if you can figure out the math a DMM could give you the basic information.
