Channel Master LTE And 5G Signal Filter Blocks Cellular Interference For TV Antennas Weatherproof Indoor And Outdoor Coaxial Device CM3201

This filter does exactly what it's supposed to do. The trick is determining whether you need one to solve any reception problems you're having.In the US, frequencies above 608 MHz (UHF channel 36) are now used for services other than broadcast TV, but your TV antenna still receives them. If strong enough, these signals can overload antenna amplifiers or TV tuners, making your reception even worse. So this filter removes those higher-frequency, non-TV signals from your antenna cabling, preventing such overload and the reception problems it can cause. This could be a problem if you have an LTE or 5G tower within a block or two of your home. If the nearest such tower is farther from your home than that, you probably won't experience any interference from cell towers, and won't need this filter.Another use of this filter is to use an RF modulator to add your own TV channels to your home's antenna cabling on those higher frequencies. The filter will both keep LTE/5G signals from degrading your in-home TV channels, and also keep those in-home TV channels from reaching your TV antenna and being broadcast (which could cause interference to nearby cell phones and would be illegal).By the way, don't worry if your TV already has channel numbers above 36. Nowadays, the channel number you see on your TV is usually different from the channel it's broadcast on! So, if you're getting higher-numbered channels by antenna, they are broadcast at lower frequencies now, and this filter won't remove them or interfere with your ability to receive them (except the filter will slightly reduce the strength of any TV station broadcasting on UHF channels 34-36, so it could interfere with a weak TV station there.)

Well, a short introduction is in order. I used to faithfully review every purchase I made with Dropy, 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 Dropy. There was no swearing or bad language in my review and I did not violate any of Dropy'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 Dropy. 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.Dropy 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.

Thus far, I have been able to view channels, unimpeded-sans interuption. Prior to installing the filter, specific channels would pixelate, freeze or otherwise be unavailable for viewing. I thought it could be weather related, antenna, or obstructions-e.g. trees (foliage), hills, etc.-impeding the signal. After a thorough and in-depth analysis of the topic, I concluded that the interference was radio frequency (RF) energy bleedthrough-4G/5G network signal bleedthrough (or crosstalk). One can do a deep dive into the abyss of cell phone signals, rights, and FCC, "Yada Yada." This prompted my search for filters. The numerical or frequency designation that allows you to tune into the station's signal isn't always the band (UHF/VHF) Traditionally, this was a specific frequency on the radio spectrum (like old VHF or UHF TV), but now it's often a digital label. You select "Channel 4" to watch the content provided by a specific station; it doesn't mean the signal is UHF. That's the long and short of it; however, the complexity of it is simple... Get a filter. I will monitor the status quo and update this post as the winter season sets in.

I was seeing interference, in the form of pixels, on my local channels. I purchased this filter and it works great. If you have 5g phones, you may need this. My only complaint is that you need both a female to female and male to male adapter if you have a set up like the one in my photo.

We had 3 channels that that would get static in the evening hours near Atlanta, GA. We are located in a tight subdivision. This filter seems to have cleared it up. Thanks for the tips on where to place the filter when using an LNA-200 amplifier. The filter goes between the antenna and pre-amp, not between the pre-amp and power inserter.
