Hey kiddo, have you ever watched TV in a hotel or apartment building and noticed that there are many channels available without using a cable box or satellite dish? Well, that's because they use a system called SMATV (Satellite Master Antenna Television).
SMATV is like a big antenna that captures TV signals from satellites and distributes them to many TVs through cables. It's like having one giant antenna for the whole building instead of each individual having their own.
Think of SMATV like this, just like how a school bus can take many kids to school at once, SMATV can provide many TV channels to many people at the same time.
So, hotels, hospitals, apartment buildings, and other places use SMATV to give their guests or residents access to many TV channels without needing individual cable boxes or satellite dishes.
That's it in a nutshell, bud!
