TV Antenna PreAmp 1



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 built so that it can be installed outdoors near the antenna where it will provide the best results or it can also be installed indoors.  The mounting bracket included with the PreAmp 1 will accommodate a mast or mounting pole up to 2" in diameter.  The PreAmp1 can be mounted to a pole or mast with the included bracket or it can be used without the bracket and mounted using screws under the eave or to a wall.   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.)

Channel Master has designed, manufactured and sold television antenna amplifiers for over 60 years and has led the industry with popular amplifier models designed for professionals including our Titan 2 and Amplify pre-amplifier models (CM-7777HD, CM-7777V3 and CM-7778V3). Through the years, installers and industry experts have touted these professional models as the best TV antenna amplifiers on the market.

The PreAmp 1 is Channel Master's newest pre-amplifier and is an excellent amplifier for commercial installations and professionally installed residential installations.

Indoor/Outdoor Heavy-Duty Housing

Competitor TV antenna amplifiers are typically constructed with plastic and designed for indoor use only. The Channel Master PreAmp 1, like our Titan 2 professional models, is constructed of a die-cast metal housing with weatherproof ports to support outdoor installations.  The PreAmp 1 includes an optional mounting bracket for attaching the amplifier to a mast/pole or the amplifier can be used without the mounting bracket and simply attached to any flat surface using screws. The flexibility of being able to install the PreAmp 1 indoors and outdoors allows use with an indoor antenna and the ability to upgrade to an outdoor antenna in the future without having to purchase a new amplifier.  

Adjustable Amplification

Most people think more is better. This is not always the case when talking about TV antenna amplifiers. We see this all the time when consumers purchase our highest gain professional amplifier (CM-7777V3) without having the signal measurement equipment to determine how much they really need to amplify their signals. In many cases, too much signal will do more harm than good to your overall signal and reception quality. The Channel Master PreAmp 1 eliminates the need for a consumer to be conscious of signal strength while still providing an industry-leading 30dB of gain. With the inclusion of a gain switch built into the power inserter, you can easily start with the high setting of 30dB gain then if you determine that this much signal has a negative impact on your reception, you can slide the switch to the low setting of 17dB which in most cases will be a safe amount of gain and make a noticeable difference in signal quality. *When installed indoors directly behind a television set, it is recommended to NOT use the high (30dB) setting.

Passive Bypass Feature

The Channel Master PreAmp 1 has an integrated passive bypass switch that allows the amplifier to continue passing signals without amplification during a loss of power to the amplifier.  Most other amplifiers on the market will not pass signals without being powered.  This is a new feature and is the only Channel Master preamplifier with this capability. 

LTE and Out of Band Filtering

The proliferation of LTE signal towers and connected LTE devices are a common cause of intermittent television signal disruption because mobile carriers operate on frequencies that can be very close to your broadcast TV frequencies. These disruptions can result in weak signals, pixelation or even channel loss, and can be especially disruptive when using an amplifier with your TV antenna. You won’t have to worry about this with the Channel Master PreAmp 1.  Built-in filters have been finely tuned to clear your OTA TV signal path from common interference including those created by mobile 5G LTE signals as well as other wireless signals such as 4G, FM and LoRa/Helium.

Optimized for use with the Channel Master Pro-Model Antenna

The PreAmp 1 is optimized to closely match the frequency response of Channel Master's Pro-Model antenna which will enhance the overall performance of the Pro-Model antenna when properly installed.  In addition to being the ideal preamplifier for the Pro-Model antenna, the PreAmp 1 is at the top of its class when used with any high-quality Channel Master or Competitor (Non-Amplified) TV antenna.

Customer Reviews

Based on 180 reviews
antenna pre-amp and booster.

I have been unable to resolve installation issues, but the seller was very prompt in delivery and provided excellent communication.
I unfortunately bought the booster first hoping that it would solve my buffering problem but it did not.
I then bought the pre-amp and have been unable to get it installed. It may turn out that the booster is unnecessary but I won't know until the pre-amp is installed.

Excellent product

I ordered this pre-amp to replace a Channel Master 7777 on my dad's tv that quit working. (I think it may have been damaged by a lightening storm) With this pre-amp on the high setting, even the weaker stations that only showed a signal strength of about 40% are around 50% or a little higher. Excellent product and I'm going to order one for myself and replace an old radio shack pre-amp that was given to me years ago that, I suspect has been a weak point in my reception ever since I put it in. Thanks for your excellent products at a fair price.

Very well made

Installed a week or so ago, art of process to improve reception. Haven't noticed a big difference yet, but was only trying to improve a couple of channels. Next step is indoor booster. If still not satisfactory, might have to change all the cables.

Increase in signal strength

I recorded before installation and after installation of the PreAmp 1signal strengths for a dozen stations. In all cases, the signal strength increased by approximately 25%.
I'm satisfied with the PreAmp1. Works as expected.

PreAmp CM7779HD

This preamp really helps in bringing in the distant channels - without it very poor reception, but with it, I can pickup multiple channels, infact, 64 local stations.
