Channel Master's 3414 is a compact, versatile RF distribution amplifier designed for indoor use with coaxial cables. It lets you distribute amplified antenna or cable TV signals to as many as four TVs without the signal degradation caused by splitters.

The 3414 can improve reception whether the problem is weak signal strength at your antenna, or loss of signal quality due to a long cable run. Unlike the inexpensive boosters you find in hardware stores, the 3414 is a "bi-directional" design that provides a return signal path for use with a cable box or cable modem (return signal is not amplified). The included AC power supply connects to the 3414 via a short length of coax cable, which is also included.

Product Highlights:

  • compatible with antenna and cable TV signals
  • cable company approved for digital cable, HDTV, and high-speed Internet
  • bi-directional for digital services
  • amplifier gain: 8 dB
  • operating frequency range: 54-1002 MHz
  • return path frequency range: 5-42 MHz (for cable modem applications)
  • 75-ohm impedance
  • noise: 2.7 dB
  • six F-type coaxial connectors (1 input, 4 output, 1 power)
  • included AC power supply provides power to amplifier via coaxial cable connection (cable included)
  • 6000-volt surge protection
  • weather-sealed housing resists corrosion
  • 4-7/16"W x 1-1/4"H x 4-5/16"D
  • warranty: 1 year
  • Our 60-day money-back guarantee
  • RG-6 cable is recommended

Strengthens over-the-air HDTV signals

Written by: Levi from Colorado on January 11, 2016

Crutchfield Customer Review (What's this?)

This product has improved the picture quality of all the over-the-air HDTV channels I receive. It makes a big difference especially when the weather is raining or snowing. Before I hooked up this product, some HDTV channel only had 60% signal strength according the the menu on my HDTV. Now the same channels have improved to 100% signal strength. However, the signal quality percentage (a different measurement) for a few channels did not improve very much. But the important thing is that I noticed a good improvement in overall picture quality for all channels. I am using this product inside my home behind my TV stand. The coaxial cable from my antenna comes through the wall behind my HDTV stand. My over-the-air antenna mast is in the attic of my house. Another advantage to using this product is that it has 4 RF outputs for the 1 over-the-air antenna input. I have hooked up one output directly to my HDTV, another output to my Channel Master DVR (digital video recorder), and another output to my older DVD recorder/VCR which has a built-in digital tuner. Now ALL 3 of my video components with tuners have excellent signal quality for both watching TV or recording TV shows. Finally, this product has excellent build quality with a metal case/housing. (not plastic).

Pros: Improved HDTV picture quality and signal strength for all channels. Also, the flexibility to send the amplified HDTV signals to 4 different components or TVs in different rooms of the house. Solid build quality.

Cons: The only negative I can think of is that the power plug has a transformer block on it--so it takes up more space at the outlet where you plug it in. At least the 2 prongs on the plug/transformer box are both the same width so you can plug it into the outlet facing one of 2 different ways (at a 180 degree angle from each other).

Crutchfield Customer Review (What's this?)

I installed outdoor antenna and hooked up 3 televisions. All was good until I hooked up the 4th. Some stations froze their picture and I lost audio. I knew I had good reception at the antenna. I purchased and hooked up the Channel Master 3414 amplifier at the point the signal came into the home from the antenna and all my problems were solved. I now receive clear strong video and audio from all channels and even in heavy rain I have no loss of signal. I am very pleased with the performance of this amplifier.

Pros: The amplifier arrived from Crutchfield ahead of the anticipated date. Instructions for installation and hookup were excellent and installation was very easy. I spent less than a half hour removing cables from old non-amplified 4 channel connector to the Channel Master 4 channel output amplifier.

Cons: None that I am aware of.

Didn't solve problem

Written by: BobM from Texas on September 18, 2015

Crutchfield Customer Review (What's this?)

I have four TVs fed by one antenna. Three work fine, but the fourth, the oldest and farthest, has trouble with a few channels, including one of our favorites. I tried an amplifier at the TV end, which didn't give much better reception. So I installed the Channel Master in place of the splitter. It installed neatly, and added about thirty mote channels after scanning. Unfortunately, it didn't improve the troublesome channels at all. I'm disappointed. Alternatives now are expensive.

Pros: Compact and solid.

Cons: If mounted outside, providing power is complicated.

Crutchfield Customer Review (What's this?)

After installing my Mohu antenna and testing on a single TV I was pleased with picking up 61 channels in my location. Using the channel master disto amplifier I now have those 61 channels on 4 separate TV's. Time to cut the cable back to just Internet.

Pros: Easy install. Rated for indoor and outdoor (installed in crawl space)

Cons: None at this point.

Seems to work fine

Crutchfield Customer Review (What's this?)

set up channel master antenna with rotor, amp, preamp & dvr...get 40 channels on chimney mount, 1 story house...old neighborhood with many large trees obstructing signal. Pixelation during bad weather & hard to zero in northern stations due to curvature of the earth, southern stations are more clear. Can zero in stations with the remote that goes with the rotor box. DVR has all the features of a cable/satellite dvr, could have an extra tuner that only watches channels but does not record. If you record 2 shows at the same time you can't watch a third, 1tb storage & can connect external drives only if not recording.

Pros: stronger signal

Cons: pixelation in bad weather

Crutchfield Customer Review (What's this?)

Great product. I've had this amp for about a month now and what a difference. I had 1 station that was continuously dropping out and thanks to this product, that issue is a thing of the past. I've been able to eliminate all my splitters, ended up with twice the free over the air channels and the signal is perfect.

Pros: Quick & easy to install Heavy duty construction

Cons: None

I have used Channel Master products in the past because of their quality and it's refreshing to see that they have not changed. The installation was very easy and the amplifier works perfect. I know there are many distribution amps on the market today but you won't go wrong with Channel Master.

Pros: Easy installation, comes with everything needed for quick set up, solid construction

Crutchfield Customer Review (What's this?)

Placed it in the "home run" box in my game room so I could split my antenna signal to several rooms (most importantly my garage) because in did not want to pay extra for another box to go in the garage. All connected tv's added 15-20 channels over using standard splitter. LOVE the fact that power is run through coax so you can choose any length you need. Thinking seriously about adding another (non-splitter type) right at the antenna because Im sure that would improve the signal much more since it amplifies a stronger signal. The fact that you can run power through existing coax cables is genius because I can simply plug another up in the same place and use this coax to run power up to the antenna. Great product. Far cheaper than the ripoff of cable....

Pros: Ease of use smart power supply

Cons: Doesn't make dinner

Crutchfield Customer Review (What's this?)

I purchased this distribution amp to resolve a problem with intermittent drop-outs. The improvement was very slight if at all. With a directional, high-gain antenna, a rotor, a pre-amplifier and this distribution amplifier, drop-outs should be non-existant. I don't know if I've got another problem or this distribution amp is not functioning correctly. An email to Channel Master support went unanswered.

Pros: Looks pretty.

Cons: Doesn't seem to do much.

Have this connected in my attic with a Channel Master 3010. Connected all the previous owner's direct tv cables to the signal amplifier and now I have free HDTV in multiple locations throughout the house. All without a cable/satellite bill.

Pros: None

Cons: Didn't come with an electrician to run a outlet in my attic. :) JK...I knew I would have to get this done when I bought it.

Crutchfield Customer Review (What's this?)

Excellent product! We have some long cable tv runs resulting in some irritating snow. This amplified splitter is just what we were looking for and cleared our tv pictures beautifully! Easy hook-up and instant success! Also, kudos to Crutchfield for excellent service! The product was out-of-stock for some time. The Crutchfield team let me know as soon as it was available, I ordered it and it arrived in about 3 days, well packaged and in perfect condition. Worth waiting for! Highly recommend! Thank you!?

Pros: Quality, well made product. Easy installation. Works very well for us!

Cons: None

Channel Master 3414 4 output RF distribution amplifier

Written by: Don from Knightdale, NC on March 9, 2012

Crutchfield Customer Review (What's this?)

I needed an amplifier to feed my antenna to 4 different receivers. This was the answer and it worked with no signal over loading or any kind of enterference.

Pros: Great amplifier with four outputs eliminating the need for a splitter. It gives a signal boost needed for longer cable runs.

Cons: None

Simple, works great

Written by: Scott from Cleveland, OH on January 22, 2012

Crutchfield Customer Review (What's this?)

This is a very simple, well constructed device. If you use it for its intended purpose, the amp functions perfectly. It eliminated the noise, visible lines, and distortion of other low quality amps in my four TV home setup. This is a perfect amp for home or small business use. My setup was analog only, so I can't comment on digital signals, pass-through, etc.

Pros: Small, solid build, clean and quiet power

Cons: None

I have a two channel unit like this one. It has been super on boosting signal from 50 miles away. We needed to add two more tvs so we purchased a 4 output unit. Great amplifier.

installed at distribution box to boost signal from Channel Master 4228 antennae. Replaced passive splitter with this, increased the number of channels visible from 23 to 43, with very strong signal from stations 40 miles away...

It was easier to amplify at my distribution box than at the antennae which is why I bought this rather than other amplifiers.

Antenna Signal Amplifier A+ Again

Written by: David from Cedarville, NJ on March 26, 2011

Crutchfield Customer Review (What's this?)

Upgrading from the channel master 3410 to the channel master 3414 was another great choice. We now have two HDTV's plus our older TV. I still get great reception. Plus we added a few more stations. Now we have a total of 33 channels. We can view different channels on all the TV's, at the same time and not lose any signal strength. Thanks Again Crutchfield for a great product.

Why did you buy this?

on-line reviews and Channel Masters reputation [ Stephen M.  Jan 22, 2016 ]

1 question already asked

This amplifier is intended for antenna signals. It works for over-the-air broadcast signals but I cannot make a recommendation for cable use. Channel Master's website states: Channel Master distribution amplifiers can be used in HDTV, CATV, off-air, analog and digital RF distribution applications where high performance and reliability are required. The CM 3414 is a high quality miniature four output digital TV amplifier with passive return, which means the distribution amplifier does not have any amplification for signals in the return path frequency range (5-42 MHz). This frequency range is used in cable telecommunications networks to allow cable modems and set top boxes to communicate back through the cable network. Passive return amplifiers are the most commonly used in-house distribution amplifiers by cable operators. Hope this helps. [ KEVIN  Feb 11, 2014 ]
I use the 3414 to boost my incoming over-air Antenna signal. It works great for that. I have a longer run and needed to install another one to reach that distance. Seems about every 100ft with an over air antenna. This should boost any signal but I'm not familiar with how the phone works with the cable system. Hope this helps in some way. [ Mark  Feb 10, 2014 ]
I just recently installed this at my place. We are running cable internet only but our signal coming in from the street was weaker than it should have been. The cable company tried to help boost the signal, but they stated because we weren't subscribed to cable TV also, they can only make the signal so strong (uh huh? yea right). So, I installed this and now we get a very strong internet signal, and we can get all the basic TV channels coming through the cable. An we have a few splitters too. In a nut shell, it worked really well on our weak signal, and the internet hasn't dropped since. Plus, it's only $40 bucks. that's not much of a risk. [ STEVE  Feb 10, 2014 ]
I am not familiar with cable service. My application for the distribution amplifier is to feed the signal from a regular off the air TV antenna to 4 TVs in the house. It definitely made a big difference compared to using just a regular splitter. [ Esteban  Feb 10, 2014 ]
I used 2way splitter to drive phone modem, then remaining tap directly to the Channel Master amp. Each output of the Amp goes to a separate TV, some 60' or more from the TV amp. Results are excellent. I have marginal signal strength coming into the house. [ Charles  Feb 10, 2014 ]
