OK, I know that most die hard scanner people will probably shriek at the thought of what I have done, but so far it seems to be working pretty well. I spend a lot of time in my office at work. The building is a pole barn type structure. My office is an interior room inside that structure. My 396XT does fairly well most of the time, but since about Thursday of last week my signal strength has been very weak. I think it had a lot to do with the weather, but I decided that I would experiment to try and improve it. The best part is that I already had everything I needed, except a $5 male BNC connector. I took about 30-40 feet of RG-6 coax and put BNC on both ends. I ran that through the wall of my office, and up above near the roof of the building. I attached an old Radio Shack all band rubber ducky to one end and attached my scanner to the other. I immediately went from getting a fluctuating 0-2 bars of signal to getting a constant 3 bars. Now today, the weather has cleared and I am getting a constant full 5 bars. Even though it is working well so far, do I need to be concerned about damaging anything? Thanks.
