Product Description

The Channel Master LTE Filter is designed to clear your OTA TV signal path from the common interference created by mobile LTE signals. The proliferation of LTE signal towers and connected LTE devices are a common cause of intermittent television signal disruption because mobile carriers operate on frequencies that can be very close to your broadcast TV frequencies. These disruptions can result in weak signals, pixilation or even channel loss, and can be especially disruptive when using an amplifier with your TV antenna.

I have it shot
Well I gave this a shot to see if it would fix some of the pixelation. I installed and didn't find it fixed any of it. But the picture seemed a bit better. I do have to mention that the model I got was not the 5g but the LTE must have been sort of mixed up. But I will hopefully try that next. But everyone's set up is different and experience with OTA and their area so. Give this a shot.

Well, a short introduction is in order. I used to faithfully review every purchase I made with Amazon, and that number is ample, but after I gave one unnamed product a negative review because it was a total piece of junk, that review was removed by Amazon. There was no swearing or bad language in my review and I did not violate any of Amazon's rules with that review, but it was still removed, which, in my mind, it was removed because it was a negative review of a product sold by Amazon. Thus, no more reviews on any products were written by me. Why should I waste my time giving any reviews if the negative ones would be potentially deleted.

I purchased this Channel Master LTE Filter and it's operation was so successful, my wife talked me into giving it a review.

I have an old outside antenna on my roof that worked to receive all my local channels until a heavy wet snow storm damaged some of the wings on that antenna. A repair was made and reception was restored. I might add, getting to this roof antenna was a really big pain and very dangerous because it is mounted 32' above the ground and hanging out over the edge of the roof line. Any fall from this height would be life changing if not result in death. I do not wish to ever get back up on the roof to work on this antenna again.

One local channel stated to be troublesome and eventually was impossible to view because of interruption of the 'over the air' signal. All other local channels were not interrupted. After trying an inline signal booster with no improvement, I reluctantly decided to buy a very expensive CM roof antenna. During my search for a replacement antenna, I came across this Channel Master (CM) LTE Filter and decided to give it a try before purchasing a new antenna and having to go through the major trouble of installing it onto my very high and dangerous roof.

Amazon shipped my order which I received in a few days. The install took less than three minutes and that included reading the directions. To my surprise, all my local channels were perfectly clear, including the favorite channel that previous to the install of this device, I could no longer view.

This filter is a 'magic' little device which solved my reception problems. I recommend the purchase of this filter if you are receiving intermittent signal over your roof antenna. Great product from a good company.

Hopefully this review, in its entirety, will be posted.
Sincerely, a happy customer.

Channel Master products, in my opinion, are top-of-the-line. I've owned several of their products and, so far, have not had any issues with them.

As for this LTE filter, I will say I was a little skeptical about their claims, but was pleasantly surprised. I cut-the-cord to cable years ago and hav been using and external arial antenna for a long time. Although I was able to receive all the main broadcast channels plus a few extra (32), there were a few channels that struggled to come in, especially during bad weather. I had read about LTE filter recently and thought I'd give this one a try. It's a little more expensive that many you'll find on Amazon, but it's a Channel Master, so quality is a big draw here. I received the filter and it was super easy to install. Just screw it into the cable port on your TV, then screw your antenna cable into the filter. After doing so there was no immediate difference. All the same channels still came in.

The beauty of this product really came to light when the first cloudy, raining day happened. Typically bad weather would cause the furthest TV stations from my home to disappear. I would get digital choppiness or no signal at all. Now, since I have the filter installed, I have not had a complete loss of signal. Broadcast TV stays connected even in bad weather. There is still occasional digitization, but, for the most part, the signal is much more stable.

Keep in mind that this is not a "booster". It will not help you reach broadcast antennas that are too far away. What it does do is "clean up the signal". It filters out cellular phone broadcast so that TV broadcasts aren't fighting for bandwidth. If you are struggling with channel signals dropping out, this may be the solutions you are looking for.

I know it says you won't get more channels but I do. I was having trouble with NBC's sub channel 17-1 until installing this thing. Always said "weak or no signal". Now it comes in clear as a bell. So I can watch Ella Dorsey do the weather in her tight outfits...
Thank you, Ella.
Reviewed in the United States on May 23, 2023
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.

5.0 out of 5 stars It Works
Reviewed in Canada on April 23, 2021
My OTA reception had been degrading over the last few years - tiling, frozen screens, dropped channels - and I was beginning to wonder:
- was the coax input on my TV faulty?
- was the coax cable faulty?
- was the antenna faulty?
After doing considerable research I found this filter, the ad for which described my symptoms to a "T". I decided to take a chance and bought the filter. Installation was easy but for the fact that the chassis of my TV interfered with the filter body, which I remedied by adding a short piece of coax to the filter which I then attached to the TV. Immediate success, almost total correction of the issues. No new TV, cable, or antenna required!

3.0 out of 5 stars YMMV if interference is not the problem.
Reviewed in Canada on February 13, 2024
Initially I installed ahead of a splitter and although there was no visible improvement it did not degrade what I have. I then moved it to be ahead of the pre-amp on the antenna and again nothing bad but no improvement on the most important channel which is often not visible. Signal strength is usually not the issue rather the signal quality often drops below 100%. I have found the antenna direction is much more important overall but not solving this intermittent issue.
So I thought it was worth a try given the low price. Buyer beware.
