Watch free HDTV with an outdoor antenna

Step 2:

Gear you'll need for free HDTV

Before you get started with this project, we recommend that you have the following:

  • HDTV with built-in ATSC tuner or an HDTV-ready TV with an external ATSC tuner
  • Enough shielded 72ohm all-weather coaxial cable to run from the rooftop antenna to the HDTV or receiver
  • A shorter cable length to run between TV/receiver location and the point where the cable will enter the dwelling
  • HDTV antenna (see step 3 to see how to choose the correct antenna)
  • Mounting hardware (usually included with antenna)
  • Drill, wrench, screwdriver, and so on
  • Coax grounding block
  • Enough grounding wire to extend from the antenna and grounding block to ground point
  • Grounding strap (if necessary)
  • Walkie-talkies (FRS radios) to communicate between roof and HDTV location (if it's too far to shout)
