Description
Product Overview
The Channel Master LTE Filter is engineered to protect your over‑the‑air television signal from the growing wave of LTE and 5G cellular transmissions that share the same spectrum as broadcast TV. Housed in a rugged, weather‑resistant enclosure measuring just 2.38 x 0.75 x 0.75 inches and weighing only 2 ounces, the filter can be mounted directly on any standard TV antenna feed line. It meets U.S. standards for blocking 3G, 4G, and 5G LTE signals while allowing frequencies up to 608 MHz to pass unimpeded, ensuring full compatibility with every U.S. TV channel. The low insertion loss design and Class A RFI shielding preserve signal strength, making it suitable for both legacy ATSC 1.0 and the newer ATSC 3.0 (NextGen TV) standards. The unit is available in two color options, LTE (light‑tan exterior) and FM (metallic gray), and carries the model number CM‑3201.
Usage
The filter is ideal for residential and small‑business environments where cellular towers, nearby Wi‑Fi routers, or 5G small cells cause ghosting, pixelation, or complete loss of picture. Install the filter by disconnecting the coaxial cable from the antenna, inserting the filter inline, and tightening the compression fittings. No tools beyond a standard wrench are required. Once installed, the filter works continuously, requiring no maintenance. It is especially beneficial for viewers who rely on OTA channels for news, sports, and streaming services that use over‑the‑air signals, as well as for households that have upgraded to ATSC 3.0 compatible televisions and want to preserve the higher‑definition picture quality.
Why Choose Us
Channel Master has a long history of producing high‑quality broadcast equipment, and this LTE filter continues that tradition. The product is manufactured in the United States, passes rigorous FCC testing, and carries a 2‑year limited warranty. Its Class A RFI shielding ensures that the filter does not become a source of interference itself, a common issue with lower‑grade competitors. The design features a low‑loss dielectric that minimizes signal attenuation, preserving the strength of legitimate broadcast channels while aggressively attenuating unwanted LTE bands. Customer reviews average 4.0 out of 5 stars from over 4,600 users, reflecting reliable performance and ease of installation.

FAQ
Will the filter affect my existing TV channels?
No. The filter is designed to pass all broadcast frequencies up to 608 MHz, which includes every over‑the‑air TV channel in the United States. It only attenuates frequencies used by LTE and 5G carriers, so your existing channels remain unchanged.
Can I use the filter with a digital or an analog antenna?
Yes. The filter works with any antenna that uses a standard coaxial feed line, whether the antenna is designed for digital HDTV, ATSC 3.0, or older analog signals. It simply sits inline between the antenna and your TV or tuner.
Do I need a professional to install the filter?
Installation is straightforward and can be completed by most homeowners with basic tools. Disconnect the coax, insert the filter, and tighten the compression fittings. Detailed instructions are included in the package.
Will the filter protect against all types of interference?
The filter specifically targets LTE, 4G, and 5G signals above 618 MHz. Other sources of interference, such as local electrical noise, satellite downlink, or non‑cellular RF sources, are not addressed by this product. For broader interference mitigation, consider additional shielding or a full‑range RF filter.
Is the filter compatible with ATSC 3.0 (NextGen TV) broadcasts?
Yes. The filter’s low insertion loss and wide‑band pass up to 608 MHz ensure that it does not degrade the higher‑frequency components used by ATSC 3.0, allowing you to enjoy the improved picture and audio quality of NextGen TV without LTE‑related disruptions.
