If you have the opportunity. hooking up to an external outdoor antenna will increase your receive a great deal. Not trying to get you into a big time project. I have a scanner running in the house. I ended up with an extra antenna- I had bought Workman Saturn B-100- 39 inch, no ground plane CB antenna, to try to set up a CB for a mobile home. Anyway, just because I had the Saturn B-100 laying around I used it as a receive only antenna for my scanner. All of the local channels are 155-157 MHz VHF for police, EMS, Fire. I was totally surprised as to the improvement in receive, over the attached telescoping antenna. I can pick up about my local county dispatch and mobiles. I pick up local Aeromedical helicopters. just with parts I had laying around it made the scanner a lot more enjoyable. It was a Radio Shack PRO 2001 from early 1980s.
