| Aug 13, 2018 at 2:53 | comment | added | user12947 | Okay, does anyone know where I can get a balun for a mobile CB antenna? | |
| Jul 31, 2018 at 4:06 | comment | added | user12947 | Mike. Yeah, 1/4 wave for the 11 meter band comes to 8'. Lol. The truck is 13' and one would have to get pretty darn crafty to run a co-phased set up. More so than I believe my employer would be comfortable with. I miss my Classic XL. It had mirror brackets that were perfect for mounting antennas. They even had a complete line of sight. The antennas could "see" each other. It was great until one of the antennas went bad unbeknownst to me. Damaging another radio. Thankfully I know a guy who got it up and running for fairly cheap | |

| Jul 30, 2018 at 19:34 | comment | added | Mike Waters | @DonHopper (1) The wire(s) from the mounting bracket to the truck's frame should be as short as possible. (2) A flat SWR like that could mean that you have losses somewhere. It does not always correlate with the radiation efficiency. | |
| Jul 30, 2018 at 19:14 | comment | added | user12947 | The swr is 1.2 across all 40 channels | |
| Jul 30, 2018 at 19:13 | comment | added | user12947 | Yes. Freightliners that are made in Mexico (like mine ) have the body dipped in rust proofing. I had to clean that crap outta the holes where the trucks mount is screwed in. But I've only ran 2 ground wires. One from the trucks mount and one from mine | |
| Jul 30, 2018 at 13:33 | comment | added | Mike Waters | They don't have to be straight. If they are used, they should not be run parallel with the metal frame. | |
| Jul 30, 2018 at 13:17 | comment | added | Scott Earle♦ | A quarter wavelength is around 8 feet. I think you’d be hard-pressed to go straight for 8 feet in any direction. Agreed that if the mount already bolts directly to the metal frame then it would largely be pointless | |
| Jul 30, 2018 at 13:03 | comment | added | Mike Waters | Why not cut those to 1/4 wavelength? Also, if that mount is grounded to the metal frame, these might not be needed. | |
| Jul 29, 2018 at 4:30 | comment | added | Scott Earle♦ | It’s no problem - CB is still radio, the theory is all the same no matter what. | |
| Jul 29, 2018 at 4:11 | comment | added | user12947 | Scott Earle, thank you so much! The guys at Procomm said pretty much the same thing. I know it's only citizens band but I paid good money for everything. Plus, I've had a perfectly good radio get fried because I used existing coax on a Freightliner Classic XL that was damaged. Thanks again, it's very much appreciated | |
