    • Worked as advertised
I kept on delaying purchasing an LTE filter because the reviews I read say you don't need one. I finally broke down and bought one because the picture was unbearable to watch or record. I was pleasantly surprised at how well it did in clearing up the pixelation. Plus I was able to get more stable TV stations that I had trouble getting before. A must-have if you have a pixelation problem with a cell tower close by. ... show more

    • Thank utube for its review on this product.
There is a tower about a mile away and a 4G filer on my antenna. Utube antenna guy said that towers are going to 5G now and said to buy a 5G filter. It is about $25 on Amazon. My TV stations are coming in a lot clearer and when I do lose reception, it's only for less than a minute. I'm so glad! I only watch live TV and would miss it! ... show more

    • Didn't seem to do much so I must not have needed it
Seems well made

    • Removed TV pixelation and gave me a crystal clear picture
Does exactly what it says it will do. Easy to install and made the difference between some channels being pixelated so badly that we couldn't watch a show to the same channels coming in crystal clear. A must have if you use an over the air antenna.

    • You may or may not need this (but I think you probably will)
This filter actually apparently made my broadcast TV reception worse after I installed it...but I don't intend to return it, and I assume it works as it is sort of advertised. I seemed to have better reception using the earlier Channel Master 4G/LTE filter, and at this point I have no particular reason to think that this 5G/LTE filter does not work. The thing is, this is a technical product, and can only have a beneficial effect if you are experiencing 5G/LTE interference, and you may not be. But this could change as more 5G frequency cell towers are installed. How do you know that you are experiencing 5G interference? You don't, at least not without a spectrum analyzer and several days/weeks of investigation as the power through cell towers is variable depending on usage. In some cases, I believe the power to the towers is so high that even this passive line filter won't work, other times, you just don't need it, and it reduces your TV signal strength due to insertion loss. The bottom line is that there is so much TV reception interference out there from all causes it is getting almost impossible to watch broadcast TV anymore (this has been my case). So to hang on the dream of "free" broadcast TV I use and keep a collection of various line filters, including high-pass impact interference and FM traps, and so forth. So I'm keeping this as part of my collection. ... show more

    • Stopped my pixeling
I never would have thought that the surrounding cell towers were interfering with my TV picture. After reading the article and using this product I have the most clear picture ever. What a difference!
