STEP 2:  Build or Buy an HDTV antenna

  • <30 mi.  A paperclip, 6″ of bare coax, basic rabbit ears.  Any HDTV antenna will probably work.
  • 30-50 mi. Store bought indoor flat antenna will work. A basic do-it-yourself HDTV maybe.
  • 50+ mi. Attic/outdoor antenna likely needed.

TipUse a known DIY HDTV pattern.  Unless you understand antenna signal/wave theory to research the frequencies, gain, and to calculate the resonant lengths,your wasting your time.
