## 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.)

## 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.
