I agree, higher is quite likely the single most important factor.
http://www.3starinc.com/antenna_mounts_and_masts.html is one of several sources of penetrating and non-penetrating mounting hardware.
If you have 100' of RG-6, you have roughly 5 dB loss at the frequency of KING, real CH-48. That loss and any splitters, would subtract from the net noise margin at the TV. An Antennas Direct CPA-19 preamp may be one of the easiest ways to buy a few dB improvement in net noise margin at the TV.
