When connected in-line from my silver-sensor indoor antenna, incoming signal was significantly boosted. Before using this product, the antenna could not lock onto the signal. With the in-line booster, the antenna locks on immediately and signal dropouts are very infrequent.

before I installed the unit my cable tv signal was fuzzy on all of our 5 televisions. Our cable internet was also having trouble loosing sync with our internet provider. It was very frustrating. I installed the signal amplifier right before the first splitter and it works perfectly. Cable internet speeds are around 1.4MB, blazing. All of the televisions are crystal clear also. It seems to be powerful enough for the televisions and the internet for me. Great product.

I split my coax cable to go to my cable modem and a TV tuner card. It worked o.k. for about a month. Then all of a sudden my cable modem lost the signal (I guess more people in my neighborhood signed up). The only way I could get the signal back was to remove the splitter, which meant no more TV on my PC. With very little optimism, I figured I'd take a chance on the signal booster. I couldn't hook it up anywhere near the demarc point as the manual suggests due to logistical problems, so I doubted it would work. I hooked it up between the wall socket and the splitter and, voila!, problem solved. Now not only is my cable modem signal solid, but channels that were once fuzzy on my TV tuner are nice and clear.

I didn't think this would work because I was hooking it up so far from the demarc point, but it worked like a charm.

As a hoot, I tried disconnecting it once to see if my signal would die again, and sure enough, my cable modem stopped getting a signal. Kudos to Motorla on a fine product.

I recently purchased a new Toshiba DLP HDTV. The picture right out of the box was fantastic on HD channels, great on digital channels, but only so so on some of the analog channels. I hooked up a splitter to feed part of the cable signal to the cable box and the other part directly to the TV and that helped for the analog channels. Then I read about the Motorola Signal Booster and decided to give it a try. What a difference! Digital channels are near HD quality and SD channels look a lot clearer and the colors are better. It's the best $40 I've ever spent! I was so happy with the booster I purchased another one to use in my computer room. A couple of the lower channels on the TV in there had always been fuzzy...not anymore! Finally something that does what it says it will!

I had two problems: Our house is 200 feet from the cable connection, and the inside of the house is wired with older RG59 coaxial cables rather than RG6. None of this would be a problem if it were not for digital TV or high speed Internet. Long distances and RG59 coaxial cable cannot transmit the high frequencies necessary for both. As a result, any time the strength of the cable signal dropped a little (which can happen from minor line problems or more people using cable), I would have trouble receiving digital TV and maintaining a connection with the Internet. A call to my cable provider would only confirm what I already knew...I would need to rewire the house with RG6 cable, and still might have problems because of the distance to my house. The Motorola Signal Booster, installed at the point the cable entered the house, followed by a high quality 3-way splitter, provided trouble-free operation of two cable boxes and an Internet connection. Although this signal booster amplifies only the signal received from the cable company, signals transmitted either by a computer or cable box are at lower frequencies and are more likely not to need amplification for this type of problem; however, the use of too many splitters can cause a problem.

I also have a DVD recorder, VCR, and TV that requires an analog signal so that these components can tune to the analog channels. If I had used a 4-way splitter at the cable box to do this, it would have reduced the signal strength to and from the cable box by another 7db, and provided a signal that might have been over amplified to each of the other components. The use of a "tap" (a "tap" is a splitter that sends most of the signal to one component, and a small fraction of the signal to other components), followed by a 3-way splitter on the "9 db" side of the tap solved this problem, only reducing the signal to the cable box by 1.5 db, but reducing the signal to the each of the components by 14 db. But because of the 15 db amplification of the Signal Booster, this was still a strong signal to the analog components.
