At the time I only have a BCD-396T to use in my vehicle. Being that it is a handheld and i often use it inside and away from my car and don't always have it in the car while driving I wanted a setup where i wouldn't have stuff in the way when not in use. Initially when i put the antenna on, i just had the cable running through the center pass through in the backseat and up to the front and no solid mount for the scanner. I didn't like having the loose cable in the backseat and it didn't look good. So i came up with this. I ran the antenna wire from where it enters the trunk lid over to the wheel well and behind the carpet there. From there it went through an opening between the trunk and the left side of the backseat. I then ran the cable under the baseboards on the door and up to behind the dash. Then i drilled a hole in the dash for a double sided female UHF connector and used washers to make sure it stayed in place. Then i connected the antenna wire to one side of tht. Then other other side of the connector when i am using the scanner i have a 3 foot cable i used to connect to the scanner. And when i am not using the scanner there are no loose cables laying around. For mounting the scanner i just used a standard radio shack mic clip. I like the location of the scanner, it is easy to see and operate. The antenna on the back is made by Antennex as is the trunk lip mount. I have been very pleased with the results of the antenna and my install. And before anyone says anything, i have not had any noticeable loss in the signal from the use of the coupler in the dash or the plug converters on the scanner.
