## Description

The Channel Master PreAmp 1 is a professional-quality TV antenna preamplifier designed to enhance the performance of any (no amplified) outdoor TV antenna. It will increase the antenna signal strength, improve signal quality and increase the number of channels received. It features a high/low gain adjustment switch located on the power insert and can be adjusted from the inside of the house. This amplifier also benefits from a new internal filter optimized to support current and future digital TV standards such as NexGen TV/ATSC 3.0, 4K. The weather-resistant metal housing is built to be installed next to the antenna or installed indoors for best results. This amplifier can be operated via a coaxial cable using the included power insert.

Review: Did not help OTA antenna amplified signal
Review: I still can't believe what a difference this preamp has made in my tv reception. I live in an urban apartment and rely on an indoor antenna (I have no interest in paying for cable). That has worked out reasonably well, but there has been one major network station that I simply could not get. It would flash on the screen for a few seconds, then cut out in favor of a black screen and the message that there was no signal. I have tried all sorts of different antennas and amplifiers with no luck whatsoever, but with the Channel Master preamp everything changed. The CBS station that I could not receive at all is now completely stable, and several new stations are now available. Hooking up the preamp was very easy. You do have to employ a power inverter (which Channel Master supplies), but that is no problem. The preamp is designed to go on an outside antenna installation and the power inverter sends power to it, but it can also be set up indoors. It provides 30db of gain (or a lower level of gain that is available through a simple switch) and it also has a very powerful LTE filter. I could not be happier with this product. It is worth every penny I paid.

## 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.
