Also, no matter which channel we turn to, we get the same thing... brightness doesnt seem to change anything.
Our video source is a laptop: vga --> rca video --> coax --> antenna, but we cant even get snow. just the horizontal scrolling lines on every channel.

sorry not up to laptop speed, it is an RF signal correct? out to channel 3 or 4 or what ever the RF is at? oh and a matching transformer to get to 300ohm.
