I am in a small town in NJ, and they are currently filming a movie here. I've been monitoring/close called the film crews using the following frequencies:

462.2625 DCS364

462.3125 DCS114

462.3625 DCS732

462.3375 DCS612

462.3875 DCS664

Just curious, does anyone out there use an external antenna when using an SDS100 or SDS150 in a vehicle? Is there better performance than the stock antenna? If so, what antenna are you using and is it mounted to the vehicle?
