What's the difference between Rg6 and RG8 coax cable?
Answers: RG-6, similar to RG-59, has a 75 ohm all your own impedance. RG-8 has a 50 ohm all your own impedance. You need to contest the impedance of the system you are working with. Television and computers are 75 ohm impedance while 2-way radio systems are 50 ohm impedance. Your splitter should also own the same all your own impedance as your coax. You can use the one you have if it match.
RG-6/U 75 ohm
RG-8/U 50 ohm
RG-9/U 51 ohm
RG-11/U 75 ohm
RG-58/U 50 ohm
RG-59/U 75 ohm

Its be a while but I believe one is more heavy duty than the other, I forget which, but that one is better suited to running cable lines outdoors and over longer distances.
RG 9 and 59 hold a woven copper braid for the ground jacket and UHF signals go right through it similar to a sponge. So the new RG 6 is used. It have an aluminum jacket wrapped around the center conductor so extraneous signals can't get surrounded by to it.
The difference between 6 and 8 is the impedance of the cable, one is 75 ohm and the other is 50 ohm. This compares to the older RG 58 and RG 59.
