Can anyone give me an explanation of RG6 cable sizing. Obviously they are not all the same. The main run from my antenna pre amp and the ground block I've had for a long time, don't know where I got it and can't make out if it has any markings on it at all. All I know is 2 of the 3 size compression fittings I have for RG6 cable are too small. The only one that I can get on ( by struggling) is the ones that came with my COAXMAX tool.
