If you have a full size broadcast station antenna on a regulation ground, that’s gives a proven performance. In the home and with short antennas, it’s more uncertain what will give you range, because every setup is different. You have to full-on experiment, take notes, try different things until you get the range you need.
If you can get the antenna in the clear and a good ground, that’s a place to start. Even with the antenna inside there are variations, like your power lines picking up the signal and sending it a lot farther than you might expect.
