Hit your local TA, Pilot, Flying hook, what have you truck stop and for about $5 you can buy a power plug for the radio that will plug into the cigeratte lighter. And dont go putting twin antennas on the thing, it isnt wide enough, they need at least 8 ft between them or they fight one another.. My antenna of choice is the good ole 102" stainless steel whip mounted on the left rear cornor. Radio Shack $19.99. But skip radio shack for the coax, their cables are lousy, the ends corrode terrible, and the "cable" quality is really poor. Nothing kills your ablity to talk or hear like poor quality cable. Cable should be 18' , dont coil the excess in a tight coil, loop it like a skein of yarn 14"-16" and wire tie it in the center. Tight coils act like a "choke" mess up reception, and make it very hard to get a good match. Mounted right you should have a near perfect match with the 18' cable and 102" antenna. Make sure the radio has a good ground from the radio chassis/housing to the vehicle. Next choice after Stainless steel whips is a 48" Francis. Wilsons are good too, but not any better than ether for the first two, and way more expensive. Firestick used to be a good buy, but thats was 15 years ago, the new ones are the pits. Hustler center loads used to be top shelf, way back when CB was king, the 19" Hustler ceramic center load was one of the best.

One upside is Wilson is made in the USA. As to your radio choice, its not a bad radio, but I hope you paid less than $90 for it. The Uniden Cobra 29LTD is only $59 after rebate right now at Pilot travel centers. The "soundtracker" radios from Uniden are paper weights. I will say the older Cobra 29 LTD Classics are better than the new ones ie made in Japan vrs made in China.
Microphones, get a good noise cancelling mike, ether a Turner Road King RK56, or an Astatic 636L. Forget power mikes, and for god's sake dont go getting a roger ping, bloody echo, or any of the "video game" noise makers. Be very careful of radio shops offering "peak and tune" there are a lot of hacks out there today.
