Sizable towers need to be registered with the FAA.  You can go to:

http://wireless2.fcc.gov/UlsApp/AsrSearch/asrAdvancedSearch.jsp

Type in Half Moon Bay and CA for the state for a listing.  Or better yet
the lat lon and radius.

Hey All, 


Does anyone know whether there's a map that shows the cable/wireless-tower map 
for the San Francisco Bay Coastside (i.e., from Montara to Half Moon Bay)? 


A few days ago, a truck hit a PG post on Highway 92, which traverses from San 
Mateo to Half Moon Bay. The accident caused the post to fall to the ground. 


The Coastside has one Comcast-owned, fiber-optic cable that crosses the 
mountains from Silicon Valley to the Coastside. I guess the cable must run on 
PG posts because not only did the accident cause a blackout in some areas of 
the Coastside but also the entire Coastside was left without almost any Cable 
TV, Internet, or mobile phone connectivity for practically 24 hours. 


I only have anecdotal evidence, but it seems that there was no Comcast or 
Verizon service whatsoever because Verizon leases the fiber-optic line from 
Comcast. It also seems that DirecTV and AT were not affected, and the 
theories vary as to why. Perhaps AT uses a combination of copper wire and 
wireless to service the area. DirecTV allegedly leases connectivity from AT 


I've also heard that Sprint PCS paid the owner of a building near the El 
Granada post office to use it to relay a mobile signal from there. But when I 
asked on Nextdoor about the incident no one mentioned Sprint. In prior 
discussions, Coastside residents say they avoid Sprint and AT due to their 
spotty service. And I know nothing about T-Mobile. 


The reason I ask is because this is not the first time that Coastside residents 
have been left without mobile service, cable TV, and Internet connectivity. In 
fact, it seems to be a frequent phenomenon, making me wonder that if the 
infrastructure here is so fragile what would happen in the case of the "Big 
One" or, God forbid, a Tsunami or major storm surge. 


I understand that there's a plan for emergency responders to maintain Internet 
and mobile connectivity that includes microwave connectivity, but I have yet to 
obtain the details. So I'm trying to get as much data as I can to help local 
decision-makers figure out how to make the Coastside more resilient before the 
next disaster strikes. 


Thanks, 
Yosem
