Re. multiple antennas in the attic; If you can place the antennas so one is not in front of the other, this may work. You should strive to maintain at least 4' of separation form other metal, so if you're mounting one above the other... you need to maximize the distance, at least 4'.
Metal pipe, roof flashing, duct work, etc will all skew the antenna's pattern (aim). This effect can vary from one channel to another.
If you are not using the satellite receiver as your terrestrial OTA/DTV receiver, I would recommend you run the OTA antenna separate of the satellite coax. The losses in the Satellite/TV diplexers are not great, but if they can be avoided, avoid them. Both your OTA and satellite receivers will be that much better off.
If you connect the RS antenna to the VHF port of the UVSJ, the UHF capacity of the RS antenna will be blocked. All of your UHF reception will be the responsibility of the antenna connected to the UHF port of the UVSJ. If it will fit, a single maximum performance combination antenna still seems more viable to me.

Thanks for the additional information. The channels that are true VHF (7.1, 9.1, 11.1, 13.1) come in really strong. The accessible portion of my attic runs north to south and is about 12' wide but has rafters, etc cutting through the space. I think I can relocate the existing antenna much farther than 4' away from its current position which has the best angle and least interference from the attic walls and roof. I did not know the distance necessary to keep between them. Thanks for filling in that part of the equation.
I would really like to have two separate runs for the Dish Network and antenna, however I don't have good access to the single cable that runs to the location where my TV is located. It looks like the diplexers reduce the dB by about 0.5 each and the ones I see advertised as low-loss don't say how much that is improved.
I do have another possibility that I may try after reading your discussion of using the hdhomerun devices. There are cables in the attic that are not currently being used for other devices. I may consider some other antennas to be used with them in order to record OTA to a NAS device that can be viewed over the network connection.
Thanks for the additional information. I am cursed with the personality that requires me to analyze (over analyze?) things before I take the first steps.
