And yet, forty million households in North America (DIRECTV & Dish combined) receive their TV service from a dish antenna and receiver.
When I provided info to show that troposcatter or balloons couldn’t reliably provide signal to all the dish antennas in North America you never addressed any of what I posted. You never provided any support for you assertion that they can.
Horse hockey.
The vast majority of troposcatter antenna are DISH SHAPED.
WTF else do I need to provide?
You need to provide a lot. Just because the antennas are dish shaped means nothing. I’m the same height as Batman. That doesn’t make me Bruce Wayne.
Troposcatter dishes are large (2m+) high gain dishes. DIRECTV ka/ku dishes are small with an order of magnitude less gain.
DIRECTV’s installation specs require azimuth alignment to ±0.1°. You can only get within 0.5° with a signal meter which is why installers need to use the dither procedure in the link I provided in a previous post.
Why ±0.1°? Because the ka-band is very narrow and anything outside of this tolerance is subject to signal loss such as rain fade.
This tight tolerance, the smaller dish, and lower gain are the reasons troposcatter isn’t viable for receiving DIRECTV.
Most of this data is contained in the links I already provided.
You never provided any support to refute my information.
Again, you are full of it.
You denied the ability of balloon to maintain fixed positions in order to broadcast. That was clearly demonstrated to be false.
I stated
“I’ve read of proposed military LTA craft for high altitude surveillance but even that would only be able to maintain a station keeping radius of 2km at best. IIRC, that would only apply for 50% of the time. The proposed 95% station keeping is 150km. I don’t know of any systems that have been implemented yet but those station keeping parameters aren’t good enough.”I stated that these balloons station keeping abilities aren't good enough to keep alignment with the current DIRECTV dish antennas.
You claimed the only way to get DirecTV is via satellite transmission.
It is not.
You are correct. I erroneously assumed the discussion was about satellites and not about mobile streaming. It didn’t occur to me that weren’t even talking about something other than satellites or dish antennas. Silly me for assuming the discussion was on topic.
In fact, you have ZERO concrete evidence the signal received by the dish antenna is coming from a satellite. You have a belief and that is all.
Other than the fact that troposcatter and high-altitude balloons transmit, you’ve provided ZERO concrete evidence that either can provide reliable signal to DBS dish antennas.
You merely tried to redirect the discussion away from those things with DIRECTV’s mobile streaming service. Why is that?
Because you made a false claim the only way to receive DirecTV is via satellite.
Can you show how troposcatter or high-altitude balloons can provide signal for several hundred HD channels to nearly forty million households that have DBS service? Will you support your own claims or not?

"Troposcatter systems have evolved over the years. With communication satellites used for long-distance communication links, current troposcatter systems are employed over shorter distances than previous systems, use smaller antennas and amplifiers, and have much higher bandwidth capabilities."
You’re right. Troposcatter systems have evolved and the dishes have gotten smaller. They’ve gone from 10+ meters to 2 meters.
You’re right. Troposcatter systems do have much higher bandwidth capabilities. AAMOF, these systems are capable of transmitting full HD video and data. However, they are not designed to transmit hundreds of full HD channels.
Troposcatter systems have limitations which is why the military uses them in very limited situations. The US military uses satellites for almost all of its communication and data transfer. That is unless you can show how a ship in the South Pacific and communicate with the Pentagon via troposcatter.
