Antenna Recommendation

Howdy! With prime day going on today I wanted to try and take advantage of getting a deal on something. I also have a hdhomerun on the way and I want to set up streaming on plex.

I get about 15 channels total with my current Onn flat antenna with range extender but I want to get more channels especially with the world cup on right now. Fox comes in fine but sometimes I need to move the antenna around depending on weather.

Any help would be appreciated! I'm thinking of trying my current one in the attic since I'll be able to route the coax cable to where the hdhomerun would be but if I can avoid the long wires it could be a lot easier when and if I need to make adjustments.

Thanks!
