When we moved from the Northeastern part of the United States down into Texas, I was surprised at how long we could drive and not see much of anything. Our commute home was a lonely one compared to what we were used to just outside of a major city back where we came from. We lived so far out that all the houses had two dishes. One for TV, and the other one for satellite internet in Texas. There was no cable Internet out where we lived. There couldn’t be because there was no cable at all where we lived.
It would actually look odd to not see a house with the two satellite dishes. The one receiving TV signals for satellite TV, and the other dish that looks a bit different because it both receives signals from satellites and transmits signals back to them as well. At the end of the little arm that is at the bottom of these small dishes is a device called a feedhorn on the Internet dishes. It is referred to as an LNB on satellite TV dishes. A feedhorn both downlinks and uplinks to specific communication satellites. For our dish it was all about Internet communication. TV dishes just receive info.
When you type something into a search engine page and hit enter you are sending information out over the Internet. When that info is retrieved and comes back to you, that is receiving data. A two-way communication is going on. You make requests to see stuff on the Internet or send info such as to status updates on social media or to post a picture or video. Then you look at stuff by clicking on links to retrieve data to your computer. That is surfing the Internet in a nutshell. A satellite Internet dish can easily handle all of that communication.
