I have a handheld Uniden Bearcat scanner, not sure of the model. Right now I'm using a extendable antenna I got from Radio Shack, it works good as long as the trains are within a few miles of Columbus. What I want to do is make one of my old, magnetic mount CB antennas into a scanner antenna. The antenna I have has a 2' whip with tuning rings at the base of the whip, and I want "stick" it on the roof of my deck. What would I need to do to make this work? The other idea I had is to put the Radio Shack antenna on a cord and put it outside somewhere. Good idea or bad? I would love to get a purpose made antenna but they are all out of my price range.
