hey guys and girls, not sure if this is the right place to post but i have 2 tv tuners hooked up in my car currently, im running (2) 2 chanel antennas with boosters and for some reason i cant get any local band lower chanels like chanel 2,4,6,8,12 these are all local and they dont come in in the car, however i can get all the uhf chanels fine and clear? any ideas why? i know theres a guru out there that knows this crap, please help me out. by the way everything is all hooked up correctly, if i hook up a regular tv in my garage with a regular antenna i get the vhf channels but in my car i dont, puzzling???
edit: by the way this problem is with both tuners so that rules that out. they are both wired seperatly.

Where are your antennas mounted? If you have them behind metal then you won't get signal.

they are actually mounted on the winshield one going acsoss the to and one going down the side on both sides, im thinking i should get a 4 channel rather than 2 2 channels.
