Compatible with all US TV antennas, it supports frequencies up to 608MHz and attenuates signals above 618MHz, ensuring crystal-clear digital TV viewing indoors or outdoors. Its low insertion loss and Class A RFI shielding maintain signal integrity for ATSC 1.0 and 3.0 standards, making it an essential upgrade for any antenna system facing modern cellular interference. ## Description Product description Channel Master CM-3201 LTE Filter The Channel Master LTE Filter is designed to clear your OTA TV signal path from interference created by mobile LTE signals. It blocks LTE and 5G signals that can interfere with TV antenna reception, preventing issues like weak signals, pixelation, or channel loss. How LTE Interference Affects TV Reception Cellular LTE, 4G, and 5G signals from nearby towers and mobile devices like phones, tablets, and smartwatches operate above 600 MHz. While they don’t overlap with TV broadcast frequencies, they can still interfere with TV tuners, causing pixelation, freezing, or signal loss. Strong LTE signals, whether from a cell tower or a nearby device, can overload the tuner, leading to frequent disruptions and poor TV reception. How the Channel Master LTE Filter Reduces Interference The Channel Master LTE Filter effectively reduces interference from Cellular LTE, 4G, and 5G signals operating above 600 MHz. Using advanced filtering technology, it attenuates these unwanted frequencies before they reach your TV tuner, preventing disruptions from nearby cell towers and mobile devices. This significantly reduces Cellular LTE interference, allowing your TV tuner to receive a cleaner signal for improved reception and a more stable viewing experience. Channel Master LTE Filter: Superior Performance & Specs Compared to Competitors The Channel Master LTE Filter outperforms competitors with industry-leading attenuation across the entire LTE band, ensuring maximum interference reduction. Smaller, lower-cost LTE filters struggle to match the superior performance of the Channel Master LTE Filter . Competitors: See the Difference in Performance & Specs Competitor tests show a key difference —effective LTE filters must provide at least -50 dB attenuation . The two competitor filters shown offer significantly lower attenuation , allowing more LTE interference through. This issue is common across many competitor filters, reducing overall effectiveness. Review: Amazing little device - Well, a short introduction is in order. I used to faithfully review every purchase I made with desertcart, 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 desertcart. There was no swearing or bad language in my review and I did not violate any of desertcart'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 desertcart. 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. desertcart 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. Review: This Filter Rocks!!!!! - I've had this for over a year. When I tell you this filter enhanced my picture quality, believe it! I almost never get any interference at all. Great product! ## Features - If you're experiencing TV reception issues due to LTE Interference, the Channel Master LTE Filter is designed to filter unwanted LTE signals and improve performance. However, most signal problems are caused by other factors. If this filter doesn’t resolve your issue, contact Channel Master—we’ll help troubleshoot your antenna system and find the right solution. - Meets USA Standard for filtering/blocking 3G, 4G & 5G LTE signal and preventing TV antenna interference from cell phone and nearby LTE towers. - Compatible with all TV Antennas and it passes signals up to 608MHz supporting all USA TV channels & attenuates 618MHz and above to block the new "600MHz" LTE band. - Designed to support the latest TV antenna standards in the US including Digital HDTV, NextGen TV, ATSC 1.0 and ATSC 3.0 with its low insertion loss and class A RFI shielding ensures no compromises in signal level and quality. - Important: Many types of interference are not related to LTE/5G signal interferences, this filter will help prevent interference reated to LTE and 5G signals and is a good addition to any TV antenna system. If you still have issues after adding the filter, this suggest that the interference is from somthing other than LTE/5G signal. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01JGSC5AO | | Antenna | Television | | AntennaDescription | Television | | Best Sellers Rank | #64 in TV Antennas | | Brand | Channel Master | | Color | dark gray or black | | Customer Reviews | 4.0 out of 5 stars 4,648 Reviews | | Global Trade Identification Number | 00020572032018 | | Impedance | 75 Ohms | | Item Dimensions L x W x H | 2.4"L x 0.75"W x 0.75"H | | Item Weight | 2 Ounces | | Manufacturer | Channel Master | | Mfr Part Number | CM-3201 | | Model Number | CM-3201 | | Number of Items | 1 | | Product Dimensions | 2.4"L x 0.75"W x 0.75"H | | UPC | 020572032018 | | Unit Count | 1.0 Count | | Warranty Description | 1-Year Limited Warranty | ## Product Details - **Antenna:** Television - **Brand:** Channel Master - **Color:** dark gray or black - **Global Trade Identification Number:** 00020572032018 - **Impedance:** 75 Ohms - **Manufacturer:** Channel Master - **Number of Items:** 1 - **Product Dimensions:** 2.4"L x 0.75"W x 0.75"H - **UPC:** 020572032018 ## Images ![Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - Image 1](https://m.media-amazon.com/images/I/71zbqBd+22L.jpg) ![Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - Image 2](https://m.media-amazon.com/images/I/7181gl1PG6L.jpg) ![Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - Image 3](https://m.media-amazon.com/images/I/61CM3vC5XQL.jpg) ![Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - Image 4](https://m.media-amazon.com/images/I/71JzA4MtxYL.jpg) ![Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - Image 5](https://m.media-amazon.com/images/I/61-XJImO1eL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does dc power pass thru filter to power roter at antenna?** A: The spec says 5MHz to 699MHz so it probably does not pass DC. And in most applications you don't need it to. Put it up on the antenna as the first thing. BEFORE the amplifier. BEFORE everything else. The point is to block strong 3G and cell phone signals that might overload your antenna amplifier. **Q: We have a 5G tower close by, does it block 5G also?** A: The short answer yes. This filter is specific to the US TV channel lineup. As of July 3, 2020 the last of the channel repacks were completed. TV channels above 34 or 600MHz have been removed from the TV spectrum. The 600MHz was widely used for 4G LTE and now also includes 5G. Other filters cutoff at 800MHz which going back years ago was included in the US TV spectrum yet. The Channel Master cuts off at 600MHz the now current TV channel upper frequency limit. Again, this will filter 4G lTE and 5G. **Q: will this work with a winegard lna200 boost xt preamplifier** A: Place the filter between the antenna and the preamplifier. You want to filter the offending signal before amplification, not afterwards. Antenna --> Filter --> LNA-200 --> TV. **Q: Do i need a special cable, the picture shows the output (to tv) is not a screw on connection?** A: I am answering for my son who I bought it for.. it can be screwed into the cable line or directly into the back of the tv itself... I hope this helps.... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing little device *by J***. on January 4, 2021* Well, a short introduction is in order.

I almost never get any interference at all. Great product! ### ⭐⭐⭐⭐ Very effective at removing unwanted signals from your TV antenna cabling *by M***Z on September 14, 2017* 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.) ## Frequently Bought Together - Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality - SiliconDust HDHomeRun Flex 4K ATSC 3.0 NextGen TV: 2/4 Tuners HDFX-4K - Philips LTE Filter for TV Antenna, Filters 4G 5G LTE Signal to Reduce Interference and Pixilation for Clear Digital HD TV Reception, Frequency Range 5-608 MHz, Indoor Outdoor Installation, SDW1520/27 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/32666926-channel-master-lte-5g-filter-reduces-pixelation-and-signal-issues](https://www.desertcart.co.uk/products/32666926-channel-master-lte-5g-filter-reduces-pixelation-and-signal-issues) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
