So I bought an antenna booster since I heard it helps a bit from a few people. It has a male end where I can stick it into something and female end where something can be stuck into it and a red wire coming off it? Do these ends just plug into where my deck meets the antenna cable? Where does the red wire go?

 

did it come with instructions? Im going to guess the red wire is for power and yes, the booster should go inbetween your deck and antenna
