Yes, the coax connection was good. Before I disconnected TR-40 and connected DT502 to the same coax outlet in my master bedroom, I did go through all the channels on TR-40 and saw most showing normal (a couple of weak ones were on and off). Then I hooked up DT502 and after the lengthy scan, it reported finding all but one of the available 34 channels (I felt pretty good at first). But when I went through the channels, a bunch of channels (ABC, NBC, FOX, CW, etc.) were just black screen, and only the strongest channels had normal showing (CBS, PBS, ION, etc., if connection was bad, this is impossible). Then I checked 1080D in the sitting room, which had normal showing on ABC, FOX and CW. Both outlets in master bedroom and sitting room are through -7db splitter. So DT502 is the worst to me. BTW, the zoom button of DT502 always gave "aspect ratio cannot change" message on screen even for HD channels.
After I disconnected DT502, I hooked up Insignia right away. The scan was fast, found all 34 channels, and showed pictures on all channels (with less off for the weakest channels than TR-40). Maybe it is my personal preference, I like TR-40's softer picture and warmer color than Insignia's.
