I'm looking for a new scanner antenna with a frequency range of 150-162. I have a BCT15X and my only option is a indoor back of set antenna. Please don't recommend any outdoor or attic antennas. I'm currently using a radio shack center loaded telescoping antenna. My scanner is currently sitting in my window mid level. I found an antenna but i'm not sure if it would be much of an upgrade. I would like to increase my range. I have no idea when it comes to scanner antennas but this antenna is only 7 1/2" in length and only 1/4 wave which sounds like not much. Any suggestions?
