Advertisements When should you install a Pre-Amp for OTA? Lots of things are going to be changed in the next week, and one of them is that the Premiere is going to get a direct line from the antenna (No splitters or anything). The solid copper center quad shielded RG-6 coax is going to be 80 feet long. Would a Pre-Amp help, hurt, or not make any difference in this new setup? I'm usually the "Play with it and see what happens" guy, but this is pretty much going to be a one shot deal (I CAN get back up and add/remove the pre-amp, but it's not going to be easy).
