Does anybody have any simple antenna upgrade ideas that I can buy for my Radioshack Pro 163. I am not allowed to put anything on the roof of my house. At this time, I am still using the antenna that came with the scanner. I seem to be getting alot of static on local frequencies for some reason. Can somebody please give me some ideas as to some other type of antenna I can buy or something I can do to the antenna that I have now. Thanks.
