How the San Francisco TV lineup grid actually works and how to use it
The channel grid for the San Francisco market is more complicated than most people expect because of the mix of major network affiliations, bilingual stations, and translator repeaters that serve the outer peninsula and bay area suburbs. If you are trying to figure out what is on and where to find it, the standard VHF/UHF channel assignments will not always match what your TV or cable box displays. This is a practical breakdown of how the grid is organized and how to navigate it without losing your mind. I deal with this stuff regularly and I have learned that the most common mistake people make is assuming the virtual channel number equals the RF channel. It does not. A station might broadcast on RF channel 18 but display as channel 7.1 on your screen. That matters when you are doing OTA antenna setups or routing signals through a distribution amplifier. The San Francisco lineup has some specific characteristics that catch people off guard. KQED is on virtual channel 9 but its digital signal runs on RF 15. KCNJ is virtual channel 13 but sits on RF 30. Then you have the Spanish language stations like KMVB on virtual 31 and KVOS digital operations that span the border region. The translators on UHF fill in coverage gaps for the East Bay and South Bay areas.
Here is the count of the primary networks you need to know about. ABC comes through KGO-CD on virtual 7. CBS is on KPIX on virtual 5. NBC lives on KNTV on virtual 11. Fox is on KDFW simulcast structure represented here by KXTV affiliate on virtual 2. PBS is KQED on virtual 9. The CW is on KBWB virtual 26. Telemundo is on KTSF virtual 26. Univision is on KCNS virtual 31. These are the ones that matter for most households. I encountered a real problem once where a customer could not pick up any stations above channel 14 despite having a clear line of sight to Sutro Tower. The issue was not the antenna or the signal path. It was that the OTA tuner was set to only scan the 2-13 VHF band and the UHF passband was disabled in the setup menu. After enabling the full UHF sweep and running a proper auto-tune with all regions selected, the KQED and KPIX signals came in immediately at strong levels. This took maybe two minutes to resolve but I have seen people spend hours blaming their equipment for something as simple as a menu setting. Another counter-intuitive thing about this market: the strongest signals are not always the ones with the highest reported dBµV readings. Multipath interference from the hills causes ghosting that can make a strong signal appear weaker than it actually is. I once had a client who moved their antenna from the rooftop to the attic and complained about losing channels. The attic location was actually closer to the transmitters but the metal roofing reflected the UHF signals enough to create destructive interference patterns. Moving the antenna back outside and rotating it about 15 degrees toward the southwest solved the ghosting problem entirely.
If you want to get the current channel listing you should use the official FCC digital television channel database. Go to the FCC website and search by zip code. The data comes directly from the station license filings and shows the virtual channel, the RF channel, the city of license, and the modulation parameters. It is the most accurate source available. The AntennaWeb tool by lowpowerfm.org is another solid option and it cross-references multiple transmitter databases to give you predicted signal strengths for your address. For people on cable or satellite the channel lineup is different again. Charter Spectrum in the Bay Area positions the major networks on channels 2 through 11 depending on your specific package tier. Comcast Xfinity uses similar primary positions but shifts the digital subchannels around. If you have a streaming setup through YouTube TV or Hulu Live the channel numbers are completely arbitrary and tied to each platform's internal guide rather than any physical frequency. There are limitations you should be aware of. The OTA guide only covers free over-the-air broadcasts. If you need local sports networks like NBC Sports Bay Area or regional sports feeds you will need a paid subscription through a wire or satellite provider. Some subchannel streams like .2 and .3 on certain stations run at lower bitrates and may drop pixelation during fast motion scenes even when the main channel looks fine. Translator stations often carry the same content as their parent but with reduced transmitter power so reception is hit or miss depending on terrain.

One workaround I recommend for people who keep losing channel lineup data after power outages is to set your OTA tuner to save the channel map as a custom preset rather than relying on the default scan. Most tuners allow you to label each station with a consistent name and number rather than letting the auto-tune reassign everything each time you run a refresh. It takes about five minutes to set up and saves you from recalibrating your guide every few months. The frequency tables for the northern California region place the primary broadcasters in the 140 to 215 MHz range for VHF high band and the 470 to 608 MHz range for UHF. If you are building or buying an antenna make sure it covers both bands. A VHF-only antenna will miss KQED and KDTV entirely since they transmit in the UHF spectrum despite their lower virtual channel numbers. For the most up to date reference you can check the OTA Insight coverage maps or the Broadcast Design Reference site which maintains detailed technical parameters for each station in the market. These resources are updated whenever the FCC approves a construction permit or a frequency change. Station changes do happen occasionally when the FCC holds incentive auctions or when new digital translator groups get approved for specific coverage areas.
The practical bottom line is that the San Francisco channel grid requires you to pay attention to virtual channel numbers rather than RF frequencies, understand how terrain and building materials affect UHF reception more than VHF, and maintain a saved channel map on your tuner to avoid constant retuning. The tools exist to get accurate information and the setups are straightforward once you understand how the digital transition reorganized everything. Most problems come from assuming the old analog numbering system still applies or from ignoring multipath issues that are especially common in hilly urban environments.
