 Great Picture Aug 27, 2003
By Andy Tune
"andytune"
Ever since my cable company installed digital cable in my house I have had picture problems. The analog pictures were grainy and half of the digital pictures didn't come in. They just said they would arrive shortly but never did. Numerous calls to the cable company failed to come up with a permanent fix. So I decided to take matters in my own hands. Other boosters made things worse. When I saw that this one worked with digital as well as analog I decided to give it a try. I first hooked it up from the cable box to the vcr and got no improvement. So I tried hooking it up where the signal first came in before the cable reciever and it worked beautifully. Analog pictures are clearer than ever and all the digital pictures come in. No more "Please Wait" screens. I am mad that my stupid cable company refused to do this but I am thrilled to finally have what I pay for! Great product!

Truth about signal booster Apr 10, 2004
As for the people writing the other reviews on this product, you should not speak if you know nothing about Broadband. First of all, this booster will NOT increase your docsis cable modem speeds, no matter what you hear. This amplifier, installed correctly (at the entry point of your home) will boost your forward signal by +15db (allowing return signals to pass). Most cable modem operating level ranges are +15 to -15, so if your within that range on your cable modems operating frequency (for example 705mhz) there is no need for a booster. If you are on the treshhold of signal, like -17db, then this amp will be beneficial to you. Your GUI on your cable modem will give you this reading (http://192.168.100.1 for example). As for your cable reception, and amplifier can be helpful if you have multiple TV's, to make up for the loss that your splitters create. But again, this amp MUST be installed @ your cables entry point to your home. If you have a bad connection though, you will only amplify noise. So your outside drop connection from the pole must be good for an amp to work properly. In conclusion, your modem downloads a config file from your ISP which tells that modem what speeds to run at, and your ISP's router capacities determine what kind of speeds you get. So this amplifier will NOT boost speeds :-)

Best Booster on the Market Dec 19, 2005
By FiOS TV GUY
Prior to purchasing the Motorola amp, I purchased and installed the TERK AMP-15, which worked very well (until the cable company did a disconnect recently and apparently short-circuited the input). Upon reconnecting my cable service, the cable-tv tech noted that my TERK AMP-15 was no longer working. Rather than just order another TERK, I decided to check the alternatives. Checking the specs, I noticed the Motorola Signal Booster is a similar product, however the specs are much better (2.5 dB max Noise Figure vs. 3.5 dB max for the TERK) and the Motorola uses the most advanced technology available (Gallium Arsenide). Also, the Motorola amp includes a 6kV surge resistant design (meets the 6kV IEEE C62.41-1991 and 1 kV Combination Wave surge for all ports). I did not find surge protection mentioned in the TERK spec. Another difference is the Motorola provides a slightly wider bandwidth (52-1000 MHz) and operates at lower dc voltage (12VDC). These differences indicate a highly refined circuit design, so I expect a much more durable, worry-free product. Nice going Motorola!

Very Good for off air HDTV signals with regular antenna Nov 10, 2005
By A. Redman
"A.R."
OK, here is a little backgroud. I have an old 6ft antenna on the roof of my house and I have a 55 inch widescreen but was unwilling to shell out for a new antenna and installation. Signal was already there but weak. About 33 - 45%. Installed the listed item and now can receive a beautiful picture. The only down side is that there still seems to be a little glitch at times for a minute or soo but it sems to be weather dependant. I also looked at the Terk version but felt this was the better option. If you already have a signal and need the extra boost to see a clear picture I definately suggest purchasing this unit. It will help.

 Real life review May 09, 2005
By Steven Moyer
I have had three (see update at the end) of these. Here are my observations and recommendations:
Out of the box, the first unit worked well and produced fair to good picture improvement but eventually started to act up after an electrical storm. It now works intermittently and often produces a degraded picture and passes no cable modem signal. Because I was somewhat satisfied with the price, performance, and brand name, I bought a second unit to replace the damaged one.
The second unit again produces fair to good picture quality but often drops the cable modem signal, which results in a climb into the attic to reset the booster. E-mail to Motorola solved the mystery as they explained that sometimes the cable signal drops below a point where it can be boosted and that causes problems. Cable services, I have read, will change the signal strength throughout the day to adjust for temperature changes that affect transmission. If the signal drops too low, my booster loses the ability to sustain modem signal connectivity and often will not regain the modem signal without a power off-power on reset.
So, I have bought yet another booster, this time a 20 dB booster by a different brand. I have also added a surge protector and would suggest that anyone who buys a booster to spend the extra $20 for an external APC cable surge suppressor.
I had to send the 20 db booster back. It produced snow and a noisy signal.
Edit - two years later, Nov. 2007: I have since moved and guess what? I left the booster in the old house and I bought Motorola booster for the new house. This one has worked well for the last two years. I'm about to move again and I'll be taking the booster with me this time....
