Thanks for responses and suggestions, guys!

mattdp - I have tried several times over the past month or so to get in touch with G&S for my install but have been unsuccessful in contacting anyone or getting a callback to the messages I have left.

Needless to say, an attic install is in order here.
Provided you have the vertical space in the attic, go all out and build a DBGH design: http://www.digitalhome.ca/ota/superantenna/design.htm
fabricate a 30x75 (or larger if you like) sheet of cardboard coated with aluminum foil (or chicken wire screen), grab some romex and fabricate the elements and feedline on a 2x4 which is then intern attached to the reflector. Go online and grab a Channel Master 0089 balun (I've seen them for $1.99). Volla! you have more UHF gain than any antenna on the market today! Don't have the vertical space? try a single bay design.
With a compass and TV Fool plot in hand, I would aim that straight at the KYIN/KIMT tower and see what happens. Also try moving around the attic if necessary. You should be totally set. If you split the cable or have long runs, try a Winegard 269 preamp if you have reception problems.
Not into fabricating your own antenna? An 8-bay of any description should more than do they job. A 4-bay should also work great.

Since the Coax is run, installation should be very easy. Get yourself some rope and tie it to a rafter. You can use just about anything to hold it up there, as long as it isn't metal. Duct tape would work, but gravity could defeat it over time. No need to ground it, because it's indoors.
As I try to find someone (more knowledgeable/experienced) to help with attic installation of a bigger antenna (e.g. the multi-bay ones you guys suggested), I tried few other things last night.
In hopes of getting more stable reception of KIMT, I replaced the radioshack VHF/UHF combo described in my previous post with the Silver Sensor. Only this time, I rotated the antenna 90 degrees (previously I had been testing by assembling the antenna as shown here
). Logic in doing so was based on both your recommendations that involved antennas that had their "elements" in the vertical plane. Turning it 90 degrees seemed to help somewhat with getting better reception for KIMT. Encouraged by this, I brought out the old Channel Master 3043 amplifier
and without much "special positining" just did a new scan.
To my surprize, not only did KIMT come in rock solid for the half hour or so that I was testing, KTTC was also solid (except for some macroblocking artifacts(?) once a minute or so - definitely watchable) even though Silver Sensor is supposed to be UHF only channel. Additionally, while scanning atleast, the TV also picked up all the channels for WHLA and WXOW - when I tried to watch these channels however, the signal strength was low and the picture kept breaking up. While these channels are unwatchable, it was certainly encouraging that by just rotating the Silver Sensor and adding the amplifier, it was able to get even the two La Crosse channels. Strangely - still no trace of either KYIN or even WLAX, which are listed above WHLA and WXOW in the TV Fool table - any thoughts why this might be? Could it be that getting WHLA and WXOW may have been a fluke due to "tropo" effect last night?
Next test I am thinking (if time permits) is to:
a) Take the Silver Sensor to the bedroom right above the living room - as this room is at roughly the same height as the attic above the garage and has a clear line of sight to Century High School and beyond.
b) Feed signal from Silver Sensor into the wall coax jack by the window.
c) In the basement - switch the cables such that the cable from this bedroom is connected to the input of the 8-way splitter instead of the output.
d) Hook-up the Channel Master 3043 between the splitter and the RG6 from the bedroom.
Reason for doing this test is to see if reception gets any better at the higher elevation especially since it is at a height comparable to the attic where the antenna might be installed. Any suggestions/input/guesses for what I can expect is appreciated.
