CB Tuning/SWR

Body mass is important as is ground plain. Some manufacturers (HD) use a metal plate under the trunk. They attach a ground to the transmitter and to the antenna. Some day I will have to experiment and see how much this helps. I know for the vhf radio on marine applications, wood and fiberglass, we used to use a fairly sizable ground plate. For automobiles and trucks this obviously isn't needed. It probably wouldn't be needed on motorcycles either if there wasn't so much plastic used now days. Might just be worth looking into.

if you set it on ch1 and 40 it should be good to go. you can all so split the difference and check ch 20 to make sure it's good to go. the swr will effect the noise level to a certain degree but there are things such as solar storms and RF in the air which will drive the noise level up. this is one thing I'm Farley knowledgeable about after driving a big rig for over 20 years.
