I got one of those kits that "extends" your antennas so you can mount them on top of your car. It allows you to fly from inside your car and stay warm in the colder weather. I attached a picture (picture is for a Phantom Standard.. could not find one for a Pro). So my question is this... is this thing going to work ?? I'm thinking about the antenna mounted (rubber suction cup) on the metal roof. Will it degrade or mess up the control signal at all?
