Doubled the OTA Channels - I am about 50 miles south of DC. I got 25 channels without the preamp, and 51 channels with the preamp. I am using a Mohu Sky antenna. I am very pleased with my increase in channels. Prior to installation, all of my channels were pixelated when it rained. I am curious if the preamp will correct this issue, as others have reported. I did use a shorter length of coaxial cable that I bought from desertcart, previously, to attach the antenna to the preamp. Otherwise, the box provided everything I needed for set up. For Channel Master: an internal diagram would be appreciated on the printed instructions. I did find one on their website. Review: Great signal booster! - Bought this to replace an older winegard amp that had died on me. This one worked way better than the old system. I only used the lower gain setting but I was able to more than double the signal strength on all the channels I checked with this system. Getting clear signals from channels I've never been able to before. Would highly recommend. Works like a champ and easy to install. ## Features - Boosts Weak Signals When Properly Installed - Compatible with all indoor and outdoor passive (non-amplified) TV antennas, this amplifier improves signal strength and quality when low signal is the actual issue. However, it will not resolve problems caused by interference, multipath, or obstructions, which are common with attic-mounted antennas. For best results, users with attic installations may need to move their antenna outdoors to achieve reliable reception. Please note: TV signal meters often do not reflect true RF levels, so the improvement may not be visible on your screen’s meter. Not compatible with antennas that already have a built-in amplifier or were originally sold with one. - Higher Power Output Compared to Distribution Amplifiers and Amplified Splitters Making it a Better Option For Weak Signal Areas and Installations with Long Coaxial Cable Runs. Compatible with Channel Master Power Passing Splitters (CM-3212HD, CM-3214HD, CM-3218HD) for Whole-Home Distribution to Multiple TV's. - Includes Built-in LTE Filter with ultra low-noise - Blocks Interference From 3G, 4G, 5G Smartphones and Transmitters with EMI & FM Out of Band Filtering (Does Not Pass FM Radio Signals) - Provides higher gain and better results compared to Standard Boosters, Significantly Enhancing Signal Strength and Quality. New design supports current and future digital TV standards like NextGen TV/ ATSC 3.0 and 4k. - Powered Over Coaxial Cable Using the Included Power Inserter, Eliminating The Need for an Outdoor Electrical Outlet. Suitable for Both Commercial and Professionally Installed Residential TV Antenna Systems. - Recommended for Use with High-Quality Passive Antennas and Accessories For optimal performance, we strongly recommend pairing the PreAmp1 with a high-quality passive antenna such as the Channel Master Pro-Model TV Antenna. Using premium coaxial cables and weather-sealed connectors from Channel Master ensures maximum signal integrity and minimizes the risk of signal loss or interference. Low-quality antennas or cables can degrade performance and reduce the effectiveness of the amplifier. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C34KVK34 | | Antenna | Television | | AntennaDescription | Television | | Best Sellers Rank | #3,217 in Electronics ( See Top 100 in Electronics ) #981 in Home Theater Accessories | | Brand | Channel Master | | Built-In Media | PreAmp 1 TV Antenna Preamplifier, Power Adapter, Mounting Bracket | | Color | Black | | Customer Reviews | 4.3 out of 5 stars 587 Reviews | | Global Trade Identification Number | 00020572799997 | | Impedance | 75 ohm | | Item Weight | 9.5 ounces | | Manufacturer | Channel Master | | Mfr Part Number | CM-7779HD | | Model Number | CM-7779HD | | Number of Items | 1 | | UPC | 020572799997 | | Unit Count | 1 Count | ## Product Details - **Antenna:** Television - **Brand:** Channel Master - **Color:** Black - **Global Trade Identification Number:** 00020572799997 - **Impedance:** 75 ohm - **Manufacturer:** Channel Master - **Number of Items:** 1 - **UPC:** 020572799997 - **Unit Count:** 1 Count ## Images ![Channel Master TV Antenna PreAmp 1-1-Port TV Antenna Pre-Amplifier, Built-in LTE Filter, 17-30dB Gain, Compatible with Non-Amplified TV Antennas, Increases Signal Strength, Indoor/Outdoor - Image 1](https://m.media-amazon.com/images/I/61bH+4uoULL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will i still need a pre amplifier with this splitter? Will both give me a better picture or do I just need one of them?** A: No, you will NOT....unless you have a cable-run from the antenna that is >100'. Then, you will need a pre-amp...but will not need the in-line amp. Pre-amps are designed to be mounted at the antenna, where there is no source power. The pre-amp is powered by the coaxial cable itself, from a power-splitter nearby a house-power source. Pre-amps are preferred to amplifiers if you have a long cable-run to your TV set, from the antenna (>100'). However, preamps need to be mounted AT the antenna. So, if you are not handy with ladders, this may not be for you. The pre-amp removes the inherent signal-loss factor of the cable run, since the cable would not be on the amplified side. An INLINE-AMPLIFIER (like this one) is usually mounted in the house's cable utility box, where the cables branch out to go to different TV sets. It is convenient to get to and no need to climb on the rooftop. HOWEVER, you'll need to have a house-power source nearby. This is usually more handy if you have cable-runs from the antenna that are <100'. AGAIN, accessibility is a breeze since you do not need to go up on the rooftop. Multiple OUTPORT port options can be found on an inline-amp. **Q: Can the booster be installed about 20ft from antenna?** A: The amplifier may be placed anywhere between the antenna and TV/DVR **Q: Is the DC power adapter included?** A: Hello, Yes the DC power supply and cable to connect it to the amplifier are included with the amplifier. Thanks, CM support **Q: Can it run on battery power?** A: It's a 12 VDC @500 mah, so yes, in theory it can run on battery, assuming a 12 VDC battery source is used, and of course, proper connection/polarity is made. This requires some basic wiring termination experience to make the experiment work safely. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great!

Works like a champ and easy to install. ### ⭐⭐⭐⭐⭐ Attic antenna with RG59/RG6 and multiple barrel connectors *by B***D on August 17, 2026* This PreAmp works great for my attic antenna. My cable run has 4 barrel connectors, 50' of RG59 cable, and 100' of RG6. VHF channels that were too weak for our Tablo to pickup before we installed this Preamp are now viewed with a very strong signal strength. No more pixel issues and power supply has enough voltage to drive the antenna through all the cable/barrel connectors. ## Frequently Bought Together - Channel Master TV Antenna PreAmp 1-1-Port TV Antenna Pre-Amplifier, Built-in LTE Filter, 17-30dB Gain, Compatible with Non-Amplified TV Antennas, Increases Signal Strength, Indoor/Outdoor - Channel Master Splitter 2 | 2-Way Splitter Distributes Digital HDTV Antenna Signal to 2 TVs, One Input and Two Outputs, Power Passing for Preamplifiers and Boosters, Low-Loss Design, Indoor/Outdoor - G-PLUG 10FT RG6 Coaxial Cable Connectors Set – High-Speed Internet, Broadband and Digital TV Aerial, Satellite Cable Extension – Weather-Sealed Double Rubber O-Ring and Compression Connectors White --- ## 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.tn/products/526949831-channel-master-tv-antenna-preamp-1-1-port-tv-antenna](https://www.desertcart.tn/products/526949831-channel-master-tv-antenna-preamp-1-1-port-tv-antenna) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-10*
