Hey all, kind of new to all of this. I have a BCD436HP and it has the ability to pick up CB. My question is, do they make a splitter/junction box that I can have a scanner antenna and a CB antenna going to it? So I would have one scanner antenna on my vehicle and a CB antenna on my vehicle as well, 2 different coax cables going to one junction box and another coax cable going to the scanner in side my vehicle. Thank you in advanced.
