What is RF ground?
In my opinion, an RF ground is something that presents a low impedance at all frequencies of interest on the desired ground surface.
All frequencies of interest usually means just the transmission frequency and all spurii.
Spurii usually include harmonics, but may include mixing products..

How high should a CB base antenna be?
60 feetGenerally, the higher the antenna is above ground, the better it will perform. Good practice is to install your vertical antenna about 5 to 10 feet above the roof line and away from power lines and obstructions. Remember that the FCC limits your antenna height to 60 feet.
Does a CB antenna need to be grounded?
Ground Your Antenna Mount If you’re using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you’ll need to make sure your antenna mount is solidly grounded to the vehicle’s chassis. A bad ground will result in an un-tunable antenna and sky-high SWR levels.
How do you ground an antenna?

How do you tell if your CB antenna is grounded properly?
If your CB antenna mount has a good ground, the multimeter needle should move all the way to the right when the probes contact these two locations. If you get very little or no needle movement on the multimeter, test that your meter is working properly by touching the two probes together.
Does coax length affect SWR?
“the length of the feedline will not change the swr it will change the apparent reading depending on what wave length you read the swr at. . just as adding a signifigant length of coax, the resultant loss will look like a lower swr.”
