You have a nice reception report...
An Antennas Direct
DB4e facing azimuth 150° magnetic would give you a shot at nearly all the strong local signals. If you want to add the second PBS station, KUON, add an Antennacraft
Y5713 to the system. The two antennas can mount on the same 10' mast. DB4e on top, the Y5713 about 4' down from the bottom of the DB4e. Use a UHF / VHF combiner such as the Antennas Direct
EU385CF
If you are still in the planning stages of construction, consider specifying that the electrical contractor mount 1" rigid conduit as a mast, or work with the roofer to optimize the installation of a tripod.
The phone, data and TV cable should all run from a single location, that way, you can do add/move/change as needed. If the basement is the logical location, that's fine. The antenna down-lead would run to the grounding point near your electrical service and then to the common location of all your cabling.
If you have many TVs to feed, you can add a distribution amplifier such as the
CM-3410 which can easily drive an 8-way splitter if needed. There are distribution amplifiers with built in splitters, but I think you pay a premium for the built in and loose the flexibility of selecting a splitter with just the right number of ports to serve the connected sets. Unused splitter ports costs you signal level.
