From here, it's around 30 degrees... antennaweb.org shows 29 and 30 degrees for all the stations - but at short distances, you being off Russell would easily account for 2-3 degrees, and it shows 44 to 45 degrees for my friend's place in Rio Pinar. A location on Russell itself shows 29 degrees or so.
I'm not convinced antennaweb is all that accurate, but I put the transmitter location coordinates in my GPS receiver... in my case, at least, antennaweb was pretty close... I'm just not sure that Rio Pinar is far enough west to get a full 15 degrees of difference in azimuth.
At any rate... if you can turn up the TV to a level you can hear at the antenna, force it to channel 40 and go out and turn it - very, very slowly - until you hear audio. Mark the mast and mount at that point.
