From the Manufacturer

Channel Master distribution amplifiers, manufactured by Channel Master's former parent company, PCT International, one of the leading manufacturers in the cable telecommunications industry, will boost your digital TV and HDTV signals, increasing their overall signal strength. They have a miniature design which will give you more space to relieve congested installs when space is at a premium. Channel Master distribution amplifiers are professional grade and meet stringent US and international standards, including those developed by the Society of Cable Telecommunications Engineers (SCTE), who creates international standards for many TV signal distribution products. 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 3410 is a high quality ultra mini single 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. Channel Master distribution amplifiers have precision machined F ports (conforms to SCTE standards) that are gold plated with beryllium copper construction to provide optimal distribution and amplification of your RF signals.

I am a professional antenna installer. This is an excellent distribution amp, but it has a specific purpose. If you attach a TV before the splitter and your signal is very strong, then this amp will be good for keeping that strong signal to all of your TVs if you install it instead of the splitter. However, if you attach you TV before the splitter and your signal is weak, this item won't help you. You would require a preamplifier.

If you need a pre-amp, Channel Master makes those well too. If you live in an urban area, opt for the 7778 as it will not amplify so much of the interference in the air from cell phone towers, wifi signals, etc. If you live in a more rural area, use the 7777 as it is a stronger apmlifier, and since you won't have so many sources of interference this will be better for you.

I live in the west end of Ottawa, and this amplifier is great when I set it up to my antenna. I had a problem getting certain channels before the amplifier, and then after I installed it, all 14 channels come in crystal clear.

Some TV connections were not getting a reliable signal all the time. All might work well and then one or another would pixelate or have trouble with sound.

Where the cable enters and is divided at a splitter I removed the splitter and replaced with the CM-6414. There were no negative effects and the number of channels detected with auto scan on the TVs increased. It works very well.

An electrical outlet is required to power the unit. The power converter and cable supplied worked out unusually well. The cable provided for power was about a foot longer than the minimum needed so no extra purchases required to finish the installation.

The ground wire that was connected to the original splitter was reused to ground the Channel Master. I would highly recommend not skipping this as the cable going outside could be struck by lightening or a wire breaking on a utility pole could fall and energize the incoming cable to a dangerous level. Probably this will never happen but a small extra step for safety is not going to hurt.

The signal after a passive 3:1 splitter is too low for two TVs. This 4-port power splitter fixed the problem. I also use a passive 2:1 splitter on the spare 4th output to feed 2 HiFi receivers. A bit expensive, but it works.

I got this a few years back to complement my OTA antenna setup. At the time I thought it would help stabilize two very weak channels I have here that were pixelating. I was wrong, instead it killed them completely. After weeks of trying to make it work, I eventually gave up. No go. In the end it I learned an expensive lesson:

A distribution amp is meant to be installed at a spot with a still relatively good signal and make it strong enough to still be receivable on the far end of a long piece of coax. It is used to control signal fade on a coax when it is being split multiple ways and/or it has to traverse long distances. It will not stabilize weak signals, in fact it will by design kill them off completely in order to limit noise over the wire. If you have a weak OTA signal to boost, what you need is an antenna amp. Antenna amps are a different beast altogether, they are installed right on the antenna mast, as close to the antenna itself as you can get it without falling off your roof. Their job is specifically to boost OTA signals normally too weak to receive.

Having said all this, it is a distribution amp and it performs as one. If you have lots of TVs in your home and a splitter is attenuating too much of your signal signal, get one, it will help you. If your cable signal is too weak at your TV/modem and your cable operator is refusing to install one of these for free, get one: put it as close to the point of entry as you can and it will help you.

This unit didn't really do what I THOUGHT it would... I thought and HOPED that it would actually work and 'boost' the antenna signal so that we could hook up and operate more than one TV..... as soon as we turn on a second TV the signal deteriorates. I wouldn't recommend this!

Yes, it seems to do the job. I'm in Winnipeg and using indoor HDTV antenna. Living in 10th floor as for now, with windows to east. Found some broadcast interruptions during bad weather conditions, especially with Global Winnipeg. Now I almost don't have such. Will use it in future for outdoor antenna as well.
