Hopefully longevity is good! Review: Works great! - I purchased this to replace a similar device that died after many years of service. (10 plus) The old amp I was using also had a high and low gain setting. I have a large antenna, (not the biggest by any means), suspended from rafters in the attic of a two story house. I live in a very rural area, miles away from any station in NE Ohio and can only pick up 3 channels without an amp, and a poor signal at that. I got this connected up and on the low gain setting am now receiving 72 channels on my Tablo TV tuner. Of course many are duplicates but still. Although my antenna is directional, I'm picking us stations from all around me. Sometimes, due to atmospheric conditions, being able to pick up things from other directions can be beneficial. An important note: Others have mentioned this but it bears repeating. More power does not always equate to better reception. Any amplifier boosts both the signal as well as the noise, so keep that in mind. It is also important to locate the amp itself as near to the antenna as possible. In my case, that is near the antenna in the attic. In my application,17dB of gain works great. It is nice to have restored all the channels I had before the old unit died. ## Features - Model 2024 - Enhanced Replacement for Titan 2 Models CM-777, CM-778, CM-7777V3, CM-7778V3 & Amplify Models CM-7777HD & CM-778HD. - Works With All Indoor Or Outdoor TV Antennas - Can Be Installed Indoors, Outdoor Or Loft Due To Its Compact Size And Heavy Duty Weatherproof Housing And Optional Pole Mounting Included. - Higher Power Output Than Distribution Amplifiers And Amplifier Splitter Makes A Better Option For Installations With Poor Signal Areas And Long Coaxial Cable Operations.

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 ### ⭐⭐⭐⭐⭐ Helps pick up tv channels!

Channels are tough to get with an antenna because of distance and our metal roofs. We could get some Channels but the digital channels would digitize a lot and some days, would not even come through. We purchased this product in hopes of picking up and maintaining channels. We found we couldn't get more channels but the clarity of our current channels blows us away. The channels are crystal clear now. Don't necessarily buy this product to get channels, buy it to clear your current digital channels to crystal clear ones, with no digitizing. This amplifier does work and I feel confident recommending it in Canada. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/689328958-cm-7779hd-preamp-1-tv-antenna-amplifier-with-5g-lte](https://www.desertcart.tn/products/689328958-cm-7779hd-preamp-1-tv-antenna-amplifier-with-5g-lte) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-11*
