Channel MasterUltra Mini 1-1-Port TV Antenna Distribution Amplifier, 15dB gain, Compatible with Non-Amplified TV Antennas, Cable and Internet Modems, Increases Signal Strength, Indoor/Outdoor

Excellent product, very easy to use. I had installed an OTA antenna some time back and was able to pick up most stations in my living room just fine, however, in my office I was missing several stations completely. Since they all run off the same antenna and I could get some stations in my office, I found this to be odd. So, I went ahead and purchased this unit along with a "PCT Series PCTMPI1G Power Inserter for Distribution Amplifiers" and had it up and running within a few minutes. Not only was the signal much stronger in my living room, but it was good and strong for all stations in my office also. Still need to run more cables elsewhere, but I'm positive this will handle them just fine.You might ask why I got the "Power Inserter" mentioned above? This box is very well made and weatherproof, so I located it outside under my eaves where I split off antenna signal to my different rooms. However, the power supply that comes with it is made to hook directly in to the box and be plugged in right next to it, but I didn't have a power outlet there. The power inserter allows me to insert the power right before my TV where I do have power and use the same cable to go back to this box. Normally the power alone would go into the top left input shown in the picture, which is clearly marked. When using the power inserter, the bottom left plug is clearly marked as being available for both power and antenna combined. The two work great together.That might be my only complaint is that I was a bit cautious trying to figure out what to use. It's not clearly documented in the descriptions. I was cautious in getting a different brand power inserter for this, had a "Channel Master" version been available on Amazon I would have gone with that. With some research I felt fairly comfortable going this way though. I would have gladly spent a bit more money to get a channel master distribution amp that included the power inserter with it though!!

A little while ago, I went to to install a C4-CJM Clearstream-4 Antenna on my roof. I had successfully tested it indoors on a short cable directly to one TV. I was getting about 30 digital channels.However, once it went on the roof, it needed 100ft of coax cable to get down to my basement. I also put in a TII 212 Lightning Surge Protector to keep my equipment safe. The problem is, this all dropped the signal immensely. Even without a splitter, I was down to about 25 channels, with one of my favorites freezing up every now and then.Yet the whole point of getting it to the basement was because I wanted to split this out to multiple TVs. With a two-way splitter (-2.5db), it was still bearable. I went down to about 22 channels per TV. However, I wanted to split it up to 3 TVs. When I tried hooking up to every source in my house with an 8-way splitter (-12.5db), it was pretty much useless. A 4-way splitter (-7db) was somewhat bearable, but I did still lose a few channels. Furthermore, the channel that froze up every now and then was now freezing every 3 seconds.That's when I decided to go with this amplifier. As opposed to a loss of signal, the Channel Master CM3418 promised 8-way splitting with a 4.5db gain. I went ahead and hooked this up with all 8 sources in my house (3 actually connected to TVs) and fired it up.The results were excellent! I'm back to 30 digital channels, and the one that flickered was coming in clearly on all 3 TVs!As for quality, the equipment seems well made and sturdy. I mounted it within my media box and was sure to hook up a ground wire. It all looks clean and organized. There is an indicator light to show that power is reaching the unit. The system came with a power adapter and a coax cable (about 3' long) to hook it up.Needless to say, I am very pleased. Excellent quality and excellent price.

This device is nice and heavy, with screw holes that let you bolt it to something. The screw holes are too small to accommodate standard drywall screws, which is kind of dumb. I have it screwed to a 2x4 in my attic, which is where the HDTV antenna is.The power cord is only 6 ft. long, so look at your setup before you decide. The power cord APPEARS to be just a length of coax, but I sure couldn't swear to it -- I dunno whether one could substitute a longer cable. So I ended up wiring an AC outlet in my attic right near the antenna. But if the cable you want to amplify comes in the house right near an existing AC outlet (hardly a rare setup), this thing will install really, really fast.When I was shopping, it took me a long time to figure out what kind of amplification I was looking for. This device seems to be designed to solve the problems of people who get good reception, but have to overcome splitters or long cable runs; it does NOT appear to be for those trying to compensate for poor reception.I had great HDTV reception, pulling in over 100 DTV channels locally. But there wasn't enough signal to make it to both of my TVs, each of which was at the end of at least 100 ft. of coax cable. Either TV connected directly to the antenna by itself was fine. Both TVs at once was pure death.There appears to be a lot of variation in people's situations with DTV, so it's hard for a reviewer to generalize. But if you have a well-situated AC outlet, and are trying to solve the problem of multiple TVs on long runs of cable, this appears to be a very good option at an easily affordable price.

Seems good so far. I believe it's stronger than my previous amplifier as the channels don't seem to cut out much.

When I first installed my OTA antenna, I already had the signal going to two TVs and got reception of 37 channels. According to TVFool, I got all the nearby signals that I was aiming for (CN Tower and Buffalo broadcasts), but not two Hamilton stations. When I split this into three TVs, I lost most of the Buffalo stations due to weakened signals.To resolve this issue, I got the 4-way distribution amplifier from Channel Master and hooked up the three TVs, leaving the fourth port unused (on a side note, I am using the pre-existing coax setup from my long-ago cable TV provider housed in an outside plastic case to pull in the OTA signal).The net result of this was that I got all of my stations back, and I got the two Hamilton stations too! So the Hamilton stations were likely too weak when I split it into two, but were restored when I used the distribution amplifier.The amplifier itself is sturdy and heavy with a smooth painted finish, so it would last even if it were completely exposed to the elements. I love that the input power is provided through a coax cable because you can use your existing coax cable installation to provide power to the unit without running another power cord into your box. I simply plugged the wall wart near one of my unused TV jacks, used a short coax cable to connect the wall wart to the jack, then connected the other end of the corresponding coax line to the power input of the unit. Very easy and I didn't have to use one of my outdoor AC outlets to power the unit. Just make sure that the power-providing coax line is completely isolated and is not connected (via splitter) to any other cables, then test the voltage (~13V DC) of the other end of the power coax cable before you screw it into the unit.

Tengo el servicio básico de televisión por cable y suele llegar débil la señal de los canales, y siempre se ven con estática o como si se encimara un canal sobre otro (se ven imágenes opacas de un canal en otro canal), por ello decidí comprar este amplificador de señal y realmente mejoro la calidad de la señal, ahora se ve sin la estática y sin imágenes encimadas, sin embargo, para que funcione el Amplificador se debe mantener todo el tiempo conectado a la luz eléctrica porque si se desconecta la señal se ve mal y con mucha estática pero cuando se conecta se ve muy bien, ademas no afecta el servicio de Internet por el contrario parece ser que ligeramente lo mejora un poco (el servicio de Internet es por cable). Si tienes interés en mejorar tu señal de televisión sin afectar tu Internet por cable considera comprar este producto, porque realmente es útil y funcional como Amplificador.Ventajas:-Mejora la Señal de Televisión (la Amplifica y se ve mejor la imagen del canal)-No hay perdida en la señal de Televisión o Internet por cable y ligeramente mejora esta ultima un poco (No es un divisor/splitter por lo que no disminuye la señal)-Es fácil de Instalar, tan solo se conecta un cable coaxial a un regulador de voltaje que el mismo producto trae, y después solo se conectan los cables al amplificador y a la luz para que el aparato funcione (trae un manual donde se muestran las conexiones, sin embargo recomiendo ver tutoriales por Internet para una mejor comprensión de su uso).-Tiene 4 salidas para la señal (Solo he usado 2; una para el cablemodem que es el internet y otra para la señal de televisión y ambas funcionan correctamente)- No se calienta en exceso, el Amplificador lo he utilizado dos días seguidos y su temperatura es lo que podría considerarse como normal (se siente tibio)Desventajas-Si el Amplificador esta desconectado de la corriente eléctrica la señal se ve con mas estática (Si no conectas el Aparato a la corriente electrica y lo quieres usar sin luz como si fuera un divisor de señal no te servirá, porque la imagen se ve mal)-Si se va la luz el Aparato no mejorara la señal, solo pasará una imagen de los canales al televisor con estática (Sin embargo si se va la luz tampoco funcionará la televisión)-Es un Aparato algo caro.-Necesita estar conectado a la luz eléctrica, o si - no la señal de Televisión no se observará bien.

I am using it to boost then YOU Broadband RF cable signal before installation my broadband internet connection was very bad and use to get disconnected frequently cable modem hated specifically near the RF cable connector. On installing this product now I get 4 to 5 mbps uplink and downlink speed and no disconnection problem and no cable modem hating problem.

This little unit does EXACTLY what it claims it will do. Namely amplify the signal so that it can be received in a far better condition at end point. I have a long cable run between my receiver and two TVs used as secondary viewing platforms. Before installing this I could barely see the picture due to a very weak signal.Now, it's like night and day. 15 db + is a large enhancement and the picture is not distorted or compromised by artifacts from the boosting process.If you have need of something like this, this unit should do the job for you.

Using it as an indoor pre-amplifier in front of a 4-way splitter. It boosts the signal a bit (without it the TV image is pixelated) but the poor-signal channels are still poor-signal and pixelated most of the time.
