I want to know what is the best antenna I can get for my 106 that will pull in the P25 signals on 450-470 range, specifically 460.225? I already have Radio Shack Discone , I gave about $75.00 for, and its not worth the plastic it came in. I will be able to spend up to about 150.00, so please give me your input. I live about 12 miles out of town, and pick up the 150-160's perfect just the 450-460 P25 that I have problem with. THANKS!
