I'd opt for the Antennas Direct DB8E. It has two sections that can be aimed independently. In your case, this allows you to make the antenna cover a wider range of the horizon.
I'd mount outdoors, and start with one panel facing about 115° (compass) and the other panel facing about 175°.
Try this with no amplifier to start with. If you are inclined to try an amplifier, perform this test first,
