I then received a sizable bandwidth booth from Comcast for ten bucks. It came with free basic cable. Sure, why not.
I installed basic cable and the HD antenna stopped working - no digital or analog signals. Coincidence? I'm just on the edge of the reception area for a strong signal so perhaps the winter weather caused signal degradation. I waited for a sunny day. Same problem.
I exchanged the antenna for a new one. No luck. I thought the problem may have been the HD converter in the TV but I'm also not receiving analog signals.
If anyone has any ideas, please do let me know.
EDIT: It's not the physical coax inputs nor is it the coax itself. Both inputs work fine with cable. The coax was switched with the new antenna.
