So I recently found out about digital OTA TV and decided to give it a try. Based on the good reviews, I bought an RCA ANT751, with the idea of installing it in the attic space above my garage. (For various reasons, I don't want to put it on the roof.)
Here is my signal analysis:

I'm able to get most of the green-shaded channels in at least some antenna locations. The strongest, most reliable signals are the three that are farthest away: KCPQ, KBTC and KTBW. My problem is that I am unable to get KIRO (CBS) and KONG at all, no matter where I put the antenna. They sometimes show up on channel scans, so there must be some detectable signal, but when I click on them, I just get snow (unlike other channels, where I see a black screen and the message 'Poor signal quality' or 'Channel not available' if the signal is too weak). The weird thing is, when I switch to KIRO, I can sometimes see a faint image of it through the snow, like an analog broadcast. But the TV signal meter shows 0%.
Any idea why I can get KOMO and KING, but not KONG and KIRO? They all come from the same location, on Queen Anne Hill. If I could get the latter two channels reliably, I could get rid of the cable. Would a pre-amp possibly solve the problem?
Geographically, I'm at a relatively high point in my neighborhood, but the end of my street in the direction of the Seattle towers slopes upward slightly.
Any help would be appreciated.
