I think the rg 58 is 50ohm and the mini 8 is 50 ohm rg 59 is 75 ohm. For a single antenna you want 50 ohm cable. Pull the screws out of your dash panel for the speedometer. Pull the panel back depending on which version of the cascadia you have you should be able to access the rubber grommet in the firewall on the drivers side. You may be able to run coax along with other wires thru grommet, use a silicon sealer if you have to make the holes bigger. You can run cable from behind dash up pillar post behind plastic to the overhead cubby hole .

I got the mini 8, like what Volvo uses I guess. Had some free time today so I installed the mount bracket I got and ran the cable. I kind of ran it like that last guy I had talked to, ran it under the hood along the cowl to the right side of the truck. But I didn't go thru the firewall like he did. I checked out the grommet on the passenger side firewall, and there was no way I could see of running the cable thru there without disassembling half the dash. Did I mention I'm a company driver and therefore can't really disassemble the truck, or be ready to swap trucks quickly if the need arises? Yeah, so I dropped the cable down on the passenger side, ran it thru the cowl panel next to the door hinge and thru the passenger side door jam and up over the the passenger side dash. I decided to run it thru the passenger side door for two reasons. 1, because stretching it out over the cowl to the right side means it's not coiled up on the dash, and 2, I never use the passenger door so it won't be subject to repeated opening/closings. Figured that would be better for it in a non-ideal environment.
Haven't mounted the antenna yet and the cable isn't hooked to the radio. Just wanted to get this much done so that when I get the money for the CB shop, I'm prepared. Here is a pic of the mounted bracket.

Time to update again. Had the money to get the swr's checked so I did that today. Will have to get the radio checked out another time. Anyway, he adjusted the antenna, said I'm good at 1.5 across the board. My question is, did he do it right? He attached the coax cable to a battery powered box with a couple dials on it. Turned a knob a couple times, took the antenna off and adjusted the tip then reinstalled, checked the dials, then readjusted the tip again. Am I ok with this? I thought the dials had to be connected to both the coax and the radio. He also said for best reception to keep the squelch turned all the way down and the gain all the way up. I don't want to listen to static all day just to be able to hear. What do you guys think?
Oh, and Mike, here is a pic showing the gap between the antenna and the cab using the bracket I showed earlier.Attached Files:
