Hi! Can anyone tell me which TV Antenna should I choose? I am currently living in a rural area. My budget is no more than 300$. I am using Ecostar LED TV. So suggest me accordingly.

They have antennas for your roof at Walmart for about 50 bucks

Yep, I bought one of those and planted it on my roof and pointed it west without doing any research. Picked up about 40 channels crystal clear. Planning on getting a rotor like the good old days to see what else I can pick up. I too live in the boonies. There are tons of trees and tall hills here so I was actually shocked I got anything.
 
This is the one I picked up.

The roof antennas are powerful compare to the inside home antennas.
My advice to all is to point the antenna towards the cable satellite or big tower antenna and scan for channels when the skies are clear multiple times.
Usually the first time you scan for channels, the antenna doesn't pick up all of them.

note antennaweb will give you a compass heading for making sure you grab the signals you want.  
 

Hard pressed to beat one of the old style giant roof mounted antenna on a small tower if you can make it happen.
 
Even if you cant rotate them. I hid one in the peak of our roof years ago in the attic and it did incredible for not even being able to point it in the optimal direction.
 
There were incredible years ago and still are the best IMO.

Put a nice booster on there from channel master and your all set

I have found that even he cheap ones pick up about the same amount as an expensive one. Of course it’s best to go with a roof if you want the most channels but you probably are not really going to improve the signals much if at all if you spent three or four times more money then a cheaper one. Facts are the technology is really so old it’s became pretty easy to do.

agreed go with a cheap one you'll be fine

I would for sure go with the budget option. Quality doesn’t matter too much when it comes to those

For rural areas, I would recommend you to use . It is especially made for rural areas. You can also read reviews of it.

If you're handy, you can actually build one that's surprisingly good for picking up long range signals, just search up db8 antenna plans

If you're looking for one on your roof, the Antennas Direct DB8e is amazing from the reviews. And bc its not solid, it blends in with the roof from a distance. I think it's like $150 last time I checked.
