Well, I ordered an antenna for the Challenger . Wilson, from what I am hearing in the CB world is having bad problems, and the word is that they will not be around much longer. Rumor has it that they are trying to sell the company, but no takers. Their inventory is running low, and some say they are having problems getting stock back up. So, I ordered a antenna while I could. Don't know what radio to use yet, or if I will be able to stick an antenna on this car or not, but at least I will have one just in case. I am leaning toward the Cobra 75WX-ST All In One CB Radio.
