Try tilting the antenna so that it points at the edge of the obstructing terrain, then experiment above and below that angle in increments of a few degrees. 45° is extreme and I can think of very few applications were a high angle like that would be useful. 15° to 20° would be the common max angle for DXing.
The HD (1080i) capable tuner and decoder has a lot more work to do than a 480i set top box... my experience is similar to yours. Reliable, full HD quality reception requires a clean signal, more so than the lower resolution. http://forum.tvfool.com/showthread.php?t=610
