Welcome to the forum. Yes, absolutely people still install antennas.
To start we need to get an idea of reception in your area. Go to tvfool.com and post your results ( your address will not be shown).
I,m located near Reading as well. There are a lot of hills and valleys as well as trees that can severely affect your reception in this area. Go to TVFOOL.COM and enter your exact location and post a link to the results here (your address will not be visible). I'm able to pickup stations as far away as Scranton a few from Harrisburg and most of the Phillie stations.
Based on your tvfool results, you have very challenging reception issues, but at the same time , you live in an area where you can possibly receive stations from different markets as 30CP has indicated above.
But in a nutshell, you are going to need at the very least a huge Lo/Hi VHF-UHF antenna mounted outdoors, a rotor to pick up different markets, and probably an amp.
