System 31: Los Angeles
Details for System 31
About the System:

This system and connecting sites have been a several year work in
progress. In April of 2017, CARLA 31 was decommissioned and re-built from
scratch on the same mountain top but in a different building/tower. The
antennas are also being migrated onto a new tower so there
may be degraded service until the final configuration is in place
(expected summer 2017). Please stay tuned for more updates.


Santiago Pk. is one of SoCal's most centralized, high level sites at
nearly 6,000' and covers a large portion of the greater LA basin &
Southland area. The site can effectively reach out to close to 40 million
