You could try aiming the two panels of a DB8e at 29 and 78 degrees to get 35, 48 and maybe 19. Then use a Y10713 aimed at 29 to get 10 and 13 and I'd expect to get 8 too, even though it's off target. But don't take my word as advice - I'm just an interested bystander.

It's also possible to combine multiple antennas using multiple tuners. Or you could use a rotator.

The narrower the bandwidth of the antenna, the higher the Q should be and the more gain I would expect for a given size and complexity. Supposedly the DB8e has an advantage over older designs for UHF because it was designed after the FCC clipped channels 51-69 from the commercial TV spectrum.
