Hello, Bill
How well an antenna will do in your friend's attic depends upon the attic construction; the signal loss is difficult to predict. If he has an aluminum foil thermal barrier, it will block the signals, and so will trees in the signal path.
As a double check on the accuracy of the TVFool report, because there have been many changes as a result of the FCC UHF Repack, here is a report by rabbit ears.info:
As far as antenna aiming is concerned, it will depend upon which channels he needs. I assume it will be:
KETK NBC, real channel 22, at 151 degrees true, 148 degrees magnetic
KLTV ABC, channel 7, 43 degrees
KFXK Fox, channel 31, 96 degrees
KYTX CBS/CW, channel 18, 140 degrees
He will need a UHF antenna with a wide beamwidth aimed at about 125 degrees for the UHF channels, and a VHF-High antenna aimed at 43 degrees for ABC.
For UHF, perhaps an Antennas Direct C2V

The C2V does have a VHF dipole, but it might not have enough gain if not aimed at channel 7
For VHF, perhaps a 30-2475

The two antennas can be combined with a UVSJ UHF/VHF combiner.

The TVFool Interactive map green signal lines can help with the antenna aim. You can move the marker by drag and drop to the antenna location:
