I'm planning to do some work on my antenna system(may add a Glomex and bypass factory antenna) but I want to try to find the antenna the factory installed first... anybody know where it is located? Also, anybody know if the Sharp 15" TV(LC 15S1U-S) that was factory installed can handle digital signals? I think it can handle 480i signals but not 480p or 1080p.... can anybody verify that? I also have a call into Grady with the same questions.
