A coaxial cable, sometimes referred to as a coax cable, is needed to connect your TV to Hofstra University's cable TV service. You can purchase this cable at most stores that sell televisions or online at sites like Amazon.com. These cables typically cost $5 to $20 dollars.
To get television service on campus, plug your coaxial cable into the port on the wall (example picture below) and to the corresponding port on your TV. Then run a channel scan on your TV to tune all of the channels available at Hofstra.
