First of all this device should only be used for your TV service. Do NOT amplify the modem line. You need to use the splitter to split one line to the modem and the other should feed the amplifier and the rest of your outlets. This amplifier will increase your modem upstream return level. Read the print on the amplifier : RTN(return) -8 dBmV. Your upstream power level will increase and your modem will have to work harder to communicate out. Also it will sometimes decrease your upstream signal-to-noise ratio (SNR).
The amplifier is not a do-it-all miracle device that will solve all of your problems. It simply amplifies the incoming signal. It does not filter the noise. This means your incoming signal needs to be clean and at acceptable level before the amplifier. So if you have 4 or more TVs (on average, but this may vary) you will most likely benefit from this purchase. If you have more than that you should buy the single port version (cheaper) and use an 8 way splitter. In fact if you buy a single port version and use a 4 way splitter you will get the same signal levels.
However if you have problems I strongly recommend calling your local cable co and get a tech out.Read more ›
So who would benefit from a cable amplifier like this? Anyone who is having difficulty receiving a solid and reliable cable TV or cable modem signal is a candidate for the BDA-S4. 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 four-output amplifier 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 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 channels.Read more ›

The cable to one of my Xfinity boxes was giving me an error and occasionally going out. Turned out the signal was not strong enough for the HD service. Read morePublished 1 month ago by Arielle

The bi-directional function works well. Just replaced some older TVs with HD ones and it seemed the new digital HD boxes put a strain on the signal. Read morePublished 4 months ago by S. Hale
