Airliners affect my over the air digital tv signal

I'm only a couple miles from a major tv transmitter (Sutro Tower). Almost every time an airliner flies overhead, the tv signal quality drops considerably for 10 to 20 seconds. What gives?
 
Maybe the new system that allows mobile phones to work from planes ?

Oz is closing down the older channels and selling the frequencies to mobile phone companies, so the frequencies can't be that far apart.
 
Dang! You already have the most expensive gasoline in the country and now this.

Call someone at the FCC. Maybe the TV station needs to modify their antenna array to keep too much signal from heading upwards. It could be an odd case of fading caused by interference when the reflected signal from the plane cancels out the signal going direct to your antenna.
 
I work at a tv station and landing planes mess up our satellite feeds, which affects EVERY viewer.

We blame their ground-finding/avoiding radar. C-band satellite is around 4 GHz.

Does this affect network programming or everything, including local commercials? Our hi-def signal is on a different satellite transponder (frequency) as our standard def 4:3 signal... as could be yours. Our DTV transmitter gets one of two options, a direct connection to the network HD feed or a standard def, "everything else" we use for local news, commercials, programming that we still feed our legacy analog transmitter and cable companies.

I have two DTV set top boxes at home and the newer one is much better at dealing with suboptimal reception-- what caused fuzz and ghosting on analog.

Call your station and ask for engineering, they may be interested in your feedback.
 
I would think that digital would be far less dependent upon signal strength compared to analog. I mean, it's been awhile since I looked at it, but the color burst and audio carrier the 4 meg of bandwidth ..etc...etc.. (iirc- it's been a very long time) ..way too many components requiring safe delivery. I would reason the "intelligence" would stay integrated with far more reliability. Then again, I guess you'll still cram as much as you can into your alloted bandwidth ....

With a digital over the air broadcast the image and sound quality remain very good up to what appears to be essentially a cutoff point. Once the signal strength display drops per the signal strength display below "good", image and sound go abruptly from very good to unwatchable with dropouts and freezing images with no sound.

I used to live about 3 miles north of Dulles airport and had Direct TV. Never had any reception problems when Lufthansa, BA and other heavyweights flew 500 feet over my property during their landing approach.

Ah ..the brief bunch of squares ...a glitch. I've seen this on my son's "Dish" thing. Kinda reminded me of Tetris ....

Directv uses circular Ku band (12 Ghz) frequencies/polarizations that are more reliable for the home user.

Did you ever get any black soot falling on your property? Perhaps like a white awning or patio umbrella turning black?

I hope they have good (and fast) fire departments!

No.

Those type of final approaches were somewhat rare; generally on order of 2-3 times per week.
