have a tv station and transmit a signal
All HD broadcasts are digital. Not all digital broadcasts are HD. "Digital" is simply a way of coding TV pictures onto a radio wave so that your TV can receive the radio wave and turn it back into a TV picture. The old method was called "analog." Digital is more efficient than analog and allows a lot more information to be carried on the radio wave. Since the wave can now carry more information, some TV stations are choosing to use that extra information for a high definition (HD) picture rather than a standard definition (SD) picture. In fact, there is so much extra room with a digital signal that most TV stations can now show several different programs at once! Most channels will now have several sub-channels. For example, instead of having just Channel 7, you might have Channel 7.1, 7.2, 7.3, and so on -- each with a different program. An HD signal takes up a lot of room, so TV stations that broadcast an HD signal have less room to add additional sub-channels. What is happening with the digital transition is that all analog TV broadcasts will be turned off. Only digital broadcasts will remain on the air. Each TV station decides what it will do with its digital signal. It can use the digital signal to broadcast one HD sub-channel and a few SD sub-channels or it can broadcast a lot of digital SD sub-channels. Most TV stations will choose to broadcast at least one HD sub-channel.
Indeed, cloud cover and rain (specifically water) cause interference in DTV signals. Severity depends on your distance from the broadcast tower.
You are going to need an external aerial for broadcast television, or a cable connection, or a streaming television source like Roku box. Subscriptions for pay TV has monthly fees. Broadcast TV is free, but you need a channel converter (to convert the signal from digital to analog so your TV can display properly) and powered antenna, and of course you will have to put up with endless commercials.
Try rescanning the set. Did the antenna get turned to a wrong direction?
The original TV was only broadcast TV. It's done the same way as radio us broadcast. Tall antenna towers send out (broadcast) radio waves that send the TV signal long distances.

Sending the same signal to many different places, like a television broadcasting station. Broadcast Transmission can be over optical fibers if the same signal is delivered to many subscribers.Jonnier Exposito
One possibility: if the signal is a digital broadcast and you have a digital-capable TV but the DVR has an analog tuner, the DVR would not see a recognizable signal, but the digital signal would pass through to the TV.
Telecasts, when any television signal is sent to another device or location.
An electronic communications system in which printed information is broadcast by television signal to sets equipped with decoders.
have a tv station and transmit a signal
only with a converter box, but then it becomes just standard definition
So they can charge more for the better video and sound. Greed.
You can use the dish but not the LNB; it will not work for dtv. The DISH Network LNB and the receiver decodes the signal and gives you a picture on your TV.
The broadcast center is the central hub of the system. At the broadcast center or the Playout & Uplink location, the television provider receives signals from various programming sources, compresses these signals using digital compression (scrambling if necessary), and beams a broadcast signal to the proper satellite. The satellite receives the signal from the broadcast station and rebroadcast them to the ground. The viewer's dish picks up the signal from the satellite (or multiple satellites in the same part of the sky) and passes it on to the receiver in the viewer's house. The receiver processes the signal and passes it on to a standard television. This was found in the year 1974.
A television repeater can be a TV translator. It receives a distant station thru a receive antenna mounted high on a tower then re-broadcast this signal from transmit antenna(s) on a different channel, mounted on the same tower.
