I bought this Motorola BDA-S1 and the PCT amp to try head to head. BTW, the PCT amp is also sold as a Channel Master product. The specifications of the PCT and Motorola amps are so similar that it seemed likely that they both contain the same integrated circuit.


This BDA-S1 certainly has the more impressive enclosure with its large, heavy and black enclosure worthy of "Tim, the tool man Taylor." However, nothing is inside of either product except one integrated circuit chip, so neither product is really superior to the other in that regard. The enclosure on the PCT is perfectly adequate.

Swapping out the Motorola and PCT amps a few times, I found that they performed identically on all stations, whether strong, extremely weak, or middle of the road. Both amps cleaned up the glitches on all of the stations that I expected to receive in pristine condition. Both amps allowed me to add one low power analog station that I couldn't receive without an amp. Neither amp caused any degradation to the quality of any station. Both amps produced identical signal strengths on all channels as measured by the on-screen signal strength meter of my plasma.

The short story is that I've given the PCT amp five stars. This Motorola BDA-S1 gets four stars for delivering the same excellent performance but at a higher price.

[Update 11/5/2012: At the time I wrote this review, the PCT amp was $25 and this Motorola was $40. Today, the PCT amp is up to $40. So, you might as well go with this Motorola just for the fancier enclosure.

So what is this thing and who would benefit from it? The Motorola BDA-S1 is a simple RF amplifier or "drop amp" which boosts a cable TV or over-the-air TV signal enough that it can be split over multiple cables to feed multiple TVs. Anyone who is having difficulty receiving a solid and reliable cable TV or cable modem signal or a clean over the air TV signal is a candidate for the BDA-S1. But first check with your cable company to make sure they have done all they can to get a high quality cable feed into your home, with high quality cables, splitters and connectors. If they've "been there, done that," and you still notice frequent outages of your cable internet service, or pixilated (distorted) images on live or recorded TV shows from cable, then you may very well need a drop amp like this one.

This amp is particularly helpful if you are splitting a cable signal coming into your house to multiple rooms for multiple TV feeds (and this is perfectly legal to do, per the Cable Act of 1992). Whenever you split a cable TV or OTA TV signal, you lose approximately 3 dB (decibels) of signal strength. Split a signal enough times and it can cause you to lose your cable modem feed or get sporadic distortion on your digital cable or digital over-the-air channels. Insert a cable amplifier like this into your cable feed as close as possible to where it enters the home and it will boost the signal enough to survive multiple splits and, in most cases, will allow you to enjoy a glitch-free cable or OTA TV signal throughout your home as well as a solid high-speed cable modem connection.

Why is this amp's "two-way" or "bi-directional" capability important?

When Comcast decided to do their digital transition, one of the DTAs would not activate properly. The only advice Comcast offered was to "remove any splitters." That was not really an option without losing cable service to most of the house.

After replacing the cable run to the problem DTA with new cable, I was now able to activate the DTA but the signal was still degraded to the point that several of the channels were unusable. Internet search indicated that the problem I experienced is not uncommon and suggested an amplifier.

Of course, Comcast will send a tech out to fix, but it is at homeowner's expense. I was not willing to pay them to fix a problem they created.

Installed amplifier--quick and easy. There was a comprehensive installation sheet, but it was not really necessary since amp inputs and outputs are well marked. Before installation, signal strength at the DTA input was about 15db with a S/N ratio of about 25. After installing the amplifier, the signal level is 1.5db and the S/N ratio is 37. Works great and I didn't have to pay Comcast to fix the problem. My only complaint is that I had to do it in the first place. My cable service wasn't broken before they implemented their transition. After, I have lost service to two TVs (unless I want to pay them extra for additional DTAs), I have a rat's nest of wires behind each of the TVs where I installed DTAs, and there is no particular improvement in service (unless you count several additional channels which are completely worthless.)

But this isn't about Comcast--it's about the amplifier.

Five+ stars. Solidly built, as you'd expect from Motorola.

If you're having problems after Comcast "improved" your service, I highly recommend you take a look at this solution.
