So, after all was said and done, this weekend...I did not install the scanner in my Tucson. After running the power, I still had the static interference on low band. I was very disillusioned at that point. Rather than go through any more hassle, I decided to yank the BC355N out of the vehicle and use it as my new base in the house. I am going to get a 100-200 channel portable to use in the vehicle. I am looking for recommendations in a thread I created in the Radio Shack scanners area.
As far as the Radio Shack antenna I bought, I just have it in the house and am using it in place of the back of set antenna on the BC355N. I will use that for the portable in the car once I get the portable. Then I will look toward some type of all-band antenna for the attic for my base.
My Scanners: Uniden Bearcat BC355N, Uniden Bearcat BC125AT, RadioShack PRO-2014, Bearcat 210XL
