Knoxville, TN Area

So on the coverage map I see there are several people around the Knoxville, TN area. I am literally so new to this I have to ask questions all the time. What kind of systems are other people in my area using? How do you have your antennas set up?

I’m using the Wifi Expert set up, with a PiAware, and some raspberry thingie. Right now the stock antenna is sitting in the window. I do semi-well as I track planes up into Kentucky, over into North Carolina, over to Johnson City.
