I'm already convinced I live in overload territory. I have a channel 49 with a noise margin of +83 dB and a channel 50 with a noise margin of +75 dB and several strong FMs nearby. I'm wondering if there is ANY way to overcome the losses I have without introducing overload with a preamp. That's my only question. The 85' of cable alone introduces around 4 to 5 dB of loss, and that's a lot of loss which roughly equates to a third of what the signal is at the antenna!!
