## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A great picture with no interference and great support from the company.
  

*by H***S on Reviewed in the United States on April 26, 2021*

The antenna is nice looking, works great and was easy to install with very patient help from the company.  Would like to get another for our bedroom, but no accessible window near the TV.  I would recommend this antenna highly to anyone wanting something other than the exorbitant price of Dish or Direct TV.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fantastic for cord-cutters
  

*by C***S on Reviewed in the United States on June 28, 2022*

I was spending a lot on cable and with some of the apps out there I could just stream everything I wanted on my internet connection and my smart TV, except local channels. I have tried many digital antennas in the past and they never really worked very well. I disconnected my cable connection from the box outside and connected this. The entire house gets great reception of local channels and there are so many more than the cable companies offer. I get over 50 local channels just from this antenna.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    easy to set up
  

*by M***O on Reviewed in the United States on January 20, 2020*

I find it dose not pick up as many local stations as I would like.  It is probably how I have to have it set up.  Talked to the tech support folks and they were very helpful.
