Review: Trusted Brand and Works Great - Had to replace my old powered 8db gain per channel Splitter( different brand) due to power failure surges. I live in a rural area. I went with this 7.5db gain per channel Splitter(close enough). This is very sturdy, seems to be well made. Has a little weight to it which surprised me. Very easy to hook up and works well with no loss I can see. Also, had to replace the 28db PreAmp( different brand) at the antenna. Used the Channel Master adjustable 17 to 31db gain PreAmp. Even set at the low end I am able to pick up about twice the amount of channels during a scan. Picture very sharp and clear. Very pleased with these units and Channel Master.
Review: The darn thing actually works! - I live in the mountains surrounded by trees. I have a good digital over-the-air antenna, but I live far away from most of the TV signals. Mountains, Trees, Distance. If you want to kill an over the air signal that's how you do it. I've tried a half-dozen of these booster things with virtually no benefit, and honestly I was hesitant to buy another one. I'm familiar with the Channel Master brand, so I rolled the dice and decided to give it a try. I was ready to accept failure once more, and was startled that my reception increased by 40%, maybe 50%! Signal strength for existing channels and I'm now receiveing channels that I didn't know existed. I changed nothing with my antenna or conditions. I simply added this to the antenna line that feeds three TV's and plugged it in. It works great! I'm very surprised. Now I'm an electrician so installing this was easy for me, and in reality if you have an electrical outlet that can be used to power it, and are capable of attatching the TV co-ax cables, this is an easy installation. If you need someone to help you, don't hesitate, it's an easy install for someone who is versed in such things. This is an easy 5 stars. I'm still surprised and very pleased at how well this Channel Master Booster works. I didn't think it could be done.

## 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.

## 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.

### ⭐⭐⭐⭐⭐ It works. Strengthns the signal and supports its distribution to several TVs.
*by W***R on January 21, 2026*

I was having a hard time with the Antenna signal strength, especially distributing it to the 4 TVs in the house that are quite apart, with long coaxial cable runs. I replaced an aging splitter/amplifier with this one and the results are nothing short of amazing. Instead of 60+ channels, TVs capture 106 channels! All with solid signal. So if have a similar case, this is well worth a try. It made a difference, and resolved the occasional frustration with weak signals that would cause pixelation.
