That's certainly not on the sectional - the dark magenta box I'm seeing says "CTC NORCAL APP WITHIN 20 NM ON 127.0 298.95"; no transmitter info included ... skyvector.com/… | |

The one thing I've learned from all of my other RF experience however is that any mapping application is of limited use and probably wouldn't tell you anything you haven't figured out by flying around in the area. | |

The actual transmitters for The Voice Communications are going to be located someplace on the airport property and that would be where you would determine your line of sight from. You would want to look for a few masts with vertical antennas. Separated by 30-40 feet. | |
| Feb 24, 2017 at 16:59 | comment | added | CJBS | Whilst this is useful background information on VHF transmissions (+1), the question is with regard to where transmitter locations are. As mentioned in the question, in a given location there are some facilities that I can communicate with easily, while others require being quite high to avoid signal obstruction from hills. Hence wanting a map of frequency/facility transmitter locations. | |
