Site Details

Notes

Dennis has kindly offered up his site to host antennas pointing towards downtown San Francisco, an area with poor coverage. He has also obtained permission from the local managers for us to host antennas inside the secure fenced area.

Future Plans

• Dennis has requested 3 public backbone IPs for use with the repeaters at the site.

Completed Work

July 2023

• Two AREDN nodes, and a backbone link has been installed.. The AREDN sector points due north towards San Francisco. The Backbone line points across The Bay to Fish Ranch.

June 2023

• With the mounting of the new pole at the site, we can move forward with an AREDN system.
