Tv tuner reception

I have just installed a mobile set up. I have a dvd/tv tuner. Reception is just ok, some channels come in but others just barely. I have four diversity inputs on the tuner but only one input is used, if I add more antennas will reception improve? Also I have a wireless FM modulator, sound is not that clear, anything I can do to improve sound quality?

rf mods suck all of them no way to fix that but yes more antennas you add more than likely the better reseption you will get  so try it i am sure you will be able to return them if no success. Jon
