Site located on San Bruno Mountain. Near the KTSF transmitter (map)(photos)
Site Details
Tower has a 4° slope. All equipment must be mounded on galvanized supports which are themselves attached to the tower using tower clamps. Cabling must be run with tower camps and stainless steel zip ties and cannot be directly attached to the tower. Cables run into the shack via rubber "grommets" (not the plastic tube!). All current mounting brackets should be considered unusable.
The site provide main power (without backup) as well as 24vdc, 12vdc and -24vdc (breakers not provided) with battery backup.
Configuration
Currently the site has an Mikrotik hAP, a Ubiquiti NSM5 (bearing 236° toward Colma), a Ubiquiti Rocket M5 + 120 degree sector antenna (bearing 160° toward Millbrae), a Ubiquiti EdgePoint R6 switch, and a Ubiquiti AirFiber dish pointing at Fish Ranch.

Plans
- Add a rack shelf
- Move the hAP onto the rack shelf
- Replace the R6 with a UISP router
- Add galvanized support for new radios to tower
- Add airFiber link to San Carlos
- Reposition W2GMD-SANBRUNO-RM5 to point at Daly City
- Replace W2GMD-SANBRUNO-NSM5 with Rocket + Sector Antenna
- Reposition airFiber link to Fish Ranch for optimal signal strength

Coordination
The San Bruno Mountain HAM site is own and managed by Matthew Kaufman as part of the WB6ECE Repeater Group. Coordination of changes to the site (e.g. new radios) is managed on the mailing list Sbruno_shack. Unfortunately this is an invite only group with no public archives.
Commercial Neighbors
The local WISP in this area is Etheric although they use a different tower. They license (WQTV709) spectrum from 11.2 GHz to 11.7 GHz.
