Customer Review: Great Product
Summary: 5 Stars
This is my second Motorola Signal Booster 484095-001-00 Bi-Directional RF Amplifier. The first got fried recently after many years of service. I've used this product with both cable and over-the-air digital TV signals. It won't work miracles, though. If the signal coming into your house is too noisy, amplifying it won't help. But if you have a good signal and long cable runs and/or multiple splitters, then this may be what you need. I'm currently using it to amplify the signal from an antenna array in my attic (three antennas in three different directions mixed with a three way splitter) before mixing the signal into the satellite cable with a RCA Antenna Satellite Diplexer Splitter and then using another one at the other end of the cable to separate the signals again. The OTA signal is then split between several different tuners. Without the Motorola signal booster, I can only see the strongest two local channels carrying NBC and CBS. With it, I can get good signals from the channels carrying ABC, Fox and PBS too. I have the signal booster and the satellite DVR plugged into APC UPS systems so recording won't be interrupted in the event of a power failure.
Customer Review: Excellent Choice
Summary: 5 Stars
This is a very good amplifier. We purchased one to go with an unpowered multi-directional digital TV antenna (RCA ANT1500). It replaced an RCA Model VH121 amplifier which we had used some years ago with analog TV when we lived further from town. With its lower noise figure and its better ability to handle digital signals, it enabled us to pick up digital stations reliably that had previously came in and out, it found some new ones, and it increased the signal strength of those we already had. It gets better though. Unlike the RCA which had connectors for RF and cable on the top (they all came up and out) this one mounts flat with all the cables coming in from the sides which makes it a very low profile and allows it to be mounted horizontally or vertically out of sight. It is also much smaller in height, about a third of its predecessor's height. But maybe the best thing of many good things is the power connection. The amplifier has an AC adapter which mounts to a power outlet BUT the connections between the adapter and the amplifier are through a shielded RF cable. So if you run the power and the signal cables up together - as you almost have to - there is much less of a chance of getting power interference on the signal line. There are also two RF cables of six foot length each supplied in the box, very generous lengths for included cables.Customer Review: It works, but not under/for every condition

I tried using this unit with my cable system. But, instead of improving my signal, it made it noisier. So, it didn't work in that setting. My setup was: "cable in -->moto booster -->cable splitter-->tv" Now, I did check my modem's signal "power level" and it went from "3.9" to "16.9" which is a major improvement in that aspect. But, it didn't do much for video. But, I may be in the minority because a lot of the other reviewers are having excellent results. Oh, one curious thing is that when I looked into my cable modem's settings, the log read the date as 1970 instead of 2008. Once I removed the booster from the connection, it read 2008.
Now, I plugged in the unit to my outdoor antenna being used for over-the-air HD stations and it worked great. I'm getting two more stations I wasn't before.
Although it didn't work for my cable video signal,I gave it five stars because it did work for my antenna and cable modem.
Update:
Ok, my initial review was a bit wrong. I've been using this booster with my over-the-air antenna for HD reception and it works great. Now, when it comes to cable tv it did improve my video signal as well. My video signal went from a few grains to perfectly clear clean signal. I may have to order a second one. This is the first signal booster that I'm confident to recommend.

I purchased this booster about a year ago and was waiting to see if it would stand the test of the other failed boosters I installed. So far it has worked great, and it was the only booster I found that could help me with my problem in the long run.
I installed a cable splitter inside a wall to accommodate my new flat panel TV and get cable signal where there were no outlet before. This saved me plenty of work avoiding fishing cables or opening walls and overall was very convenient, but the split degraded the signal to a point that some analog as well as digital channels were grainy, or their signal was spotty. I tried several signal boosters with marginal improvement, until I found this piece
I tried other splitter before, they worked fine for a short time (not as good as this one though) and then mysteriously, the signal returned to its previous state. Not with this guy
Very easy to connect, the signal improved dramatically and it had stood the pass of time. It is good that works for both, analog and digital signals. The only thing I can recommend is to connect it at the entry point of the cable TV into your apartment, as it will give you the best signal improvement rate. I think that's the way it is recommended to be connected in the manual, so if it is connected other way don't expect good results
Customer Review: Best Booster on the Market

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!
