Optimized for current and future digital TV standards including ATSC 3.0 and 4K, this compact amplifier ensures superior signal quality with easy setup and trusted Channel Master reliability since 1949. ## Description The Channel Master PreAmp 1 is a professional-grade TV antenna pre-amplifier designed to enhance the performance of any (non-amplified) professional-grade outdoor TV antenna. The PreAmp 1 will boost antenna signal strength, improve signal quality and may increase the number of channels received. The PreAmp 1 includes many features including a new high/low gain adjustment switch located on the power inserter and can be adjusted from inside the home. The ultra-low noise amplifier also leverages a new internal filter design that is optimized to support current digital TV standards as well as future TV standards such as NexGen TV/ATSC 3.0, 4K, and more. The heavy-duty weatherproof metal housing is designed to be installed outdoors near the antenna where it will provide the best results. The mounting bracket included with the PreAmp 1 will accommodate a mast or mounting pole up to 2" in diameter. There is also no need for an electrical outlet outside near the antenna, the PreAmp 1 can be powered over the coaxial cable using the included power inserter. (When installing a splitter with this amplifier it must be a power passing splitter, most common splitters will not pass power.) ## Features - New 2023 Model - Same as CM-7777HD Amplify and Titan Pre-Amplifier Models but with enhanced features. - Improves Signal Quality, Decreases Pixilation and May Increase Number of Channels - Includes Built-in LTE Filter - Blocks Interference From 3G, 4G, 5G Smartphones and Transmitters with EMI & FM Out of Band Filtering (Does Not Pass FM Radio Signals to Avoid Over Amplification Issues) - Includes Adjustable Amplification (17 dB/30 dB) with Coaxial Powering for Outdoor Installations - Trusted Quality: Channel Master Has Been Manufacturing TV Antennas, Amplifiers and Accessories Since 1949 While Offering Best of Class ************************************************************* and Support.Includes Optional Pole Mount or Can Be Mounted To a Flat Surface Using Screws.Works With Indoor or Outdoor TV Antennas - Can Be Installed Indoor, Outdoor or in Attic Due to its Compact Size and Heavy-Duty Weatherproof Housing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C34KVK34 | | AntennaDescription | Television | | Best Sellers Rank | 70,814 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 109 in Signal Amplifiers | | Brand Name | Channel Master | | Colour | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (559) | | Global Trade Identification Number | 00020572799997 | | Item Weight | 9.5 Ounces | | Manufacturer | Channel Master | | Manufacturer Part Number | CM-7779HD | | Model Number | CM-7779HD | | Number of Items | 1 | | UPC | 020572799997 | | Unit Count | 1.0 count | ## Product Details - **Antenna:** Television - **Brand:** Channel Master - **Colour:** Black - **Global Trade Identification Number:** 00020572799997 - **Manufacturer:** Channel Master - **Number of items:** 1 - **UPC:** 020572799997 - **Unit count:** 1.0 count ## Images ![Channel Master CM-7779HD PreAmp 1 TV Antenna Amplifier with 5G LTE Filter, Adjustable Gain Preamplifier - Professional-Grade Signal Booster - 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. ## 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/533471821-channel-master-cm-7779hd-preamp-1-tv-antenna-amplifier-5g](https://www.desertcart.tn/products/533471821-channel-master-cm-7779hd-preamp-1-tv-antenna-amplifier-5g) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-24*
