Site located off the Black Mountain Trail near the Rancho San Antonio Open Space Preserve in the Los Altos Hills (map)(photos)

Road to the site is private and closed by a padlocked gate. The secure area at the site is managed by Crown Castle using a timed bluetooth enabled key dropbox. There are a number of tower up at Black Mountain:

  • Site 1 - An old abandoned tower possibly still owned by Stanford University. Previously the site of the Stanford Amateur Radio Club (W6YX) repeater and Stanford's Instruction TV.
  • Site 2 - Commercial site, but with a small HAM building.
  • Site 3 - FAA
  • Site 4 - The BAY-NET tower where AREDN is located
  • Site 5 - WB6ECE Repeater Group

Site 1 is at the highest point.
