I've gone through two pairs of Comcast DTA digital adaptor boxes, that would provide SD-digital reception, to replace current analog reception. The activation signal over the cable from Comcast reaches them, as they change their onscreen messages, but no activation occurs. Is anyone else having this same problem? My cable successfully feeds an HD-DVR and an Internet cable modem and two TVs on analog signals, all at the same time. I tried hooking up one DTA box directly with the cable and nothing else connected, but it still wouldn't activate. I was told by Comcast that some of the DTA boxes may not work properly, so I exchanged the first pair for two more, with the same result. Is it possible that the RG-59 wire connection from the street may not provide enough signal strength for the DTAs, even though it runs a DVR and Internet modem just fine? A re-wiring from the street with the heavier RG-6 cable might help, but would this likely be necessary? I run RG-6 on all my connections that split from the main cable. I've gone through all this with several advisors and signal-repair techs at Comcast and haven't gotten a solution.
