re: IS "SATELLITE RECEPTION" *really* the basis for Internet, TV, and "Global Communications"?

If they are high up enough, yes. You can see half a ball when you look at it. The constraint is that they have to talk to each other and geosynchronous orbit is plenty high enough.

You're smart enough to insinuate something here but not smart enough to do so clearly.

Here's the conundrum here; If positioning of Satellite dishes on houses is stationary, how is it possible to "LOCK IN" on one specific orbiting Satellite for consistent reception IF that Satellites is whizzing away at a different position thousands of miles an hour?


It's not a conundrum, if a single satellite has line of sight to the reciever (easy to do when they are in fricken space) they can transmit a signal (moving at the speed of light) to a stationary receiver pointed at the sky.

Literally impossible with the way TV satellite systems work. Do you seriously think there is a terrestrial based relay at a 30°+ azimuth to the dishes on people's houses?

FYI - I used to teach Commercial Satellite 101 internally at work to our non-technical employees (HR, Finance, etc), so that they could speak intelligently but at a basic level to our clients, vendors and prospective employees.

NO ONE is pointing their Satellite Dish at any actual "Satellite" up in the "sky" for "better receptions"; They are pointing it in the direction of the nearest GROUND tower.


That must be one hell of a high tower out in the Gulf of Mexico that I’m pointing my dish at when at the beach. Another odd thing, all the TV dishes in the US seem to be pointing the same direction with only a difference in elevation. Everyone’s “ground tower” is the same geographic direction from their house, what are the odds?

Bump so we can hear Liberator’s take on Elon Musk losing about 40 new satellites due to a sun storm.

ETA- never mind. Didn’t see the other thread here before I posted this. As you were.

Even IF I accepted the premise that 3-4 geosynchronous "Satellites" are whizzing around a global at thousands of miles an hour IN LOW EARTH ORBIT, your theory is still geometrically impossible.

But then again you may be right; NASA has surely provided evidentiary video from Space OR at least from the Hubble of this phenomena of course. Oh wait :-(

What was "insinuated" but needed to be "clarified", Professor? I admire people who read between very large lines. Blow me away.

Do you know the different between the speed of "Light" and the speed of "Sound" frequencies?

Let's not forget -- the supposedly "line of sight" you claim must overcome angles from LOW. EARTH. ORBIT. And that's as 3-4 "satellites" traveling at blurring speeds are trying to simultaneously cover the entire "globe" WHILE syncing up with stationary ground receptors/dishes.

I already weighed in over there on Elon's great SciFi Caper.

You DO understand how radio signals and radio frequencies work, right?

At one time in the not too distant past, houses still had these antennas on their roof tops.

Believe what you need to believe.

Look around you. See all those new 5G Towers?

Few really understand the actual dynamics of how Radio Frequencies, microwave sound waves, and electricity within the aether.

What do houses in the past having antennas for reception of VHF/UHF “line of sight” TV signals have to do with my statement that it seems odd that every “Dish TV” parabolic dish in the US is pointed at the same point in the sky if they were actually receiving signals from ground stations? I seem to remember something about radio signals and rotating E+H fields from a Emag class while earning my BS in physics. The majority of home antennas used in the past for over the air reception were a hybrid yagi/logperiodic design, combining a broadband log cell with individual yagi directors to optimize gain a desecrate channel frequencies, not the two element phased dipole array shown in the advertisement you posted. I had a 35 year career working with antennas, transmission lines, wave propagation, and any other aspect of RF you can think of, your “ground tower” premise of satellite TV reception is not based in reality.

TO ALL:

Pretty cool.

VIDEO: Balloon Satellite Full Moon Transit Captured (Nikon P900 ZOOM Camera)

They are virtually impossible to see with the naked eye...

With the latest state of the art camera, Nikon P900 (especially for ZOOMING), here a videographer catches a Balloon-"Satellite" drifting across full moon. If you notice, there are 3 distinct balloons attached to the Data Payload/Receptor.

This is more likely 'G00gle Earth's' method of capturing it's earth-images.

While the deep sea cables are inaccessible, Seems like a group could hit those points where these cables come to land and blackout countries or even the entire world.

Interesting thought. Surprised there isn't a movie about it yet. or maybe there is.

The US in the past has “tapped” undersea cables to intercept Soviet communications during the Cold War using divers out of submarines. The Soviets did the same. The NSA has in the past maintained facilities next to some of these “exit points” to monitor international telephone traffic when the signals were analog.

The (bal)LOONS at NAS(uck) expect US to believe there aren’t BALLOONS on the “so called” international SPACE station! More like the cabal BALLOON floaty ORGY room. What’s really going on up there?!?!

Wake up! Question EVERYTHING?

Are you high? No one thinks their internet comes from satellites.


Forgive me for overlooking your fine post and thanking you for your sacrifice and service to TD on milestone career post #28 from the 7-11 parking lot.

For you and others, here is how your Information Overlords explain the process for the masses -- NOT me:

On what planet? Not Earth. The cables on earth have been tapped and monitored constantly since they were laid.

Yeah. THAT image of a "satellite" (sans balloon) looks perfectly legit.

DON'T "question everything"; Don't even question ANYTHING. I think we'll all be safer that way.

Dishes OR "Space" Satellites? (they are two different things, right?)

Who's claiming there's no function of antennas or your company's Dish for transmission reception?
