Is anyone running a TV tuner I have an Alpine and there are two powerd antannas I have a 2007 2500 HD the back window has defrost so where can I put them I thought about taking out the headliner and mounting them to the metal roof I had them in my Yukon one on each back side window and people thought I had tracvision it came in so clear no I have mounted them to the metal body behind the rear seat. The truck is a crew cab
