Found the right cable and attached the tiny flat window antenna thing up in the attic as a test.
Got the following channels:
8-1 NBC (3 bars) (out of 5)
8-2 Bounce
8-3 Radar
13-1 ABC (5 bars)
13-2 WX
13-3 Justice
17-1 Fox (5 bars)
17-2 Antenna
17-3 ThisTV
35-1 PBS (5 bars)
35-2 PBS
35-3 WGVU-11
35-4 WGVU-11
41-1 ABC (5 bars)
41-2 Radar
54-1 TBN (5 bars)
54-2 WTLJ-HD
54-3 WTLJ-SD2
64-1 WLLA D1 (1 bar)
64-2 WLLA D2
64-3 WLLA D3
So - I take all this to be encouraging that with a real antenna up there, I should be good to go. Thoughts or comments?
Thanks!
