I currently have a BCD996XT scanner hooked up to a Diamond D130JN antenna. I have purchased a 100 ft length of Times Microwave LMR 400 with N connectors. I have a lightning arrestor connected to the end of the 100 ft length. From the lightning arrestor I have a 15 ft length of LMR240 going to the scanner. My question is am I losing any reception in the short length of LMR240 or should I have the small jumper from the arrestor to the scanner in LMR400?
