What TV antenna's do you guys use for broadcast - I have one but can barely get 2 channels and they are both snowy no matter what I do
Your ability to receive and watch over-the-air broadcasts depends so much on the geography of your specific area. Sometimes it is impossible to get good signals because of mountains and other obstructions. Those people resort to cable or satellite. Many small rural cable companies came into existence to provide regular over-the-air broadcasts to those who could not otherwise receive them.
Naming specific antennas is a waste of time without other context. We have a basic Winegard antenna. I have no idea which model number it is, but it looks like the typical home antenna of the 1950s or 1960s, with lots of little metal rods sticking out. I looked on Amazon, and it looks similar to the model HD8200U. It has always worked well for us, whether analog or digital signals.
I run the cable directly to a PCT MA28PN - an RF splitter/amplifier, which sends the antenna signal throughout the house. I have already observed that if I disconnect the power to the box (turn off the signal amplifier), the signal doesn't degrade, so I leave it off and it is just a basic 7-port splitter.
I live in Southern California. Nearly all over-the-air radio and television signals are broadcast from Mt. Wilson, near the observatory. (Bring your induction cookware with you so you can watch eggs fry near the broadcast antennas!) Most people in Southern California have a direct line-of-sight view of Mt. Wilson and get a very strong signal, but there are pockets all over where the hills and mountains block the view. Sometimes you can get a marginal signal and boost it with an amplifier. In my experience, that fails as often as it works. With today's digital broadcasts, most of the time the images are either very clean, or unwatchable.
Because your living situation (geographically) is unknown, it is difficult to recommend a specific remedy. The first thing to do might be to find a neighbor with a good signal, and ask them how they do it.
(Caveat emptor: By the way, the eggs comment was my attempt at humor, but I swear you can feel the static electricity on your arm hairs around there.)
