This is probably not the greatest place for that question – I don’t recall much discussion of antennas here.
You might start by plugging your location into antennaweb and viewing the results. Note that even when antennaweb says you can get by with a small omnidirectional (which it won’t at your distance) it means a small outdoor antenna mounted at least 20 feet off the ground. They don’t try to predict indoor antennas at all. You want as clear a line of site as you can to the transmitting antenna, so your mounting position may matter as much as the antenna.
Banned but back. Because why not?
