I have a Uniden BCT-15 which I'll be mounting in my car, and I will probably end up getting a PC78 Elite in the near future. I'm only interested in monitoring police freqs, most of which are conventional analog systems and a few Motorola and LTR trunked systems. Can I buy a single antenna to use for both a scanner and CB radio? And can I just replace the stock antenna on my car so I don't have to do any wiring work? I never listen to the radio in my car anyway. I don't care if the antenna is huge and funny looking, I just want the best performance for under $100 that won't fall off on bumpy rides.
