Question: Will it also boost the internet signal going to my modem ?
Document: Does exactly what it's supposed to do and really boosts the power levels of the incoming signal for my Cisco DPC3010 cable modem. I definitely see a much more stable signal around peak times when neighbors are turning on their crappy old TVs and AV equipment that causes lots of noise on the line. Even with the instructions that came with the unit it took some trial and error to get the correct wiring setup for going to TV vs cable modem. It does make a difference.Also make sure your power is coming from a good clean source, as this will also effect the signal.
(You're amplifying the peaks and troughs with the DC current, so if the power feed has peaks and troughs it's self it's just going to cause more noise.... Some fluorescent lights, bad power strip, space heaters etc can cause additional noise. )Bottom line:Yes it does boost signal for Cable Modems by about 10-15db. Tested on my Cisco DPC3010 modem.Yes it works for cable boxes as well. Tested on my Motorola DCX3501M DVR.Make sure you have it cabled properly, and experiment to be sure.Make sure your power source is clean and steady.
This amp fixed the problems I was having with intermittent Internet failure and spotty HD channels. The HD channel problem only affected a few stations (in a certain channel # range which included some of my favorite channels!). The intermittent cable modem connection failure occurred after hours of workable use. The modem reported -5 to -7 dBV before the amp and -9 when using a splitter. When using the amp (which is labeled with a 11dB boost on its front, NOT 12x boost), the cable modem received +7 dBV and the HDTV returned to normal.
We were having trouble receiving some high def channels. Some were pixelated, others just didn't come through at all. We installed the BDA-S2 where the cable comes into the house, and our problems appear to be fixed. Our cable gets split to 6 different ports, and this boosts the signal at those ports to an adequate level. FDC power level went from -17 dBmV to -6 dBmV. The cable modem still works just fine. We haven't noticed an improvement in its performance but we also never really had a problem with its performance.
I do not have the instrument to measure how much it boost the cable signal. But after I split the signal in two I noticed a considerable slowing of my internet connection. After I installed this booster, my internet connection is even faster than before I split the signal. 5 stars.
I have just installed the Motorola BDA-2 and want to share my device hook ups and results.My signal into the house was fine, but I had several splits to different devices and was losing signal strength.I have three televisions, 1 set top box, 1 TV tuner on my PC and a cable modem (Cox).My cable enters the attic where I make my 1st split using a 5-1000Mhz 2 way splitter.I have one leg at the split going to my modem before the signal goes thru the amp.The other leg goes into the amp.I use two more of the 2 way splitters on the 2 amp out ports.1 leg on the splitter to my digital set top box.1 leg to a bedroom tv (expanded basic cable no digital tuner.
I decided to get this amp both to have a potentially lower power boost than the single port version and to avoid having to buy a high quality splitter. Even using RG-59 cable to the drop amp is working fine. I'm using the included power adapter with my own RG-6 coax (the box does not include any cables) and RG-6 cables out of the box. As the manual says, any unused output ports need to be terminated with 75 ohms to work properly. Note: you can also use other options including powering the amp through a TV's outlet for attic use with an optional power splitter.December 2012 update: I stopped using this amp a few months after purchasing it.
The main cable line is split once before coming into this amp. The split goes to the cable modem. The output goes to this booster, then one output goes to an 8-way splitter. The other output has an F-terminal cap.Make sure you do the math to match the signal drops. You don't want to over-amplify the signal. This product had just the right amount of signal boost for a passive eight-way splitter. Make sure you mount is somewhat near a receptacle for power.
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. Insert a cable amplifier like this into your cable feed right 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 TV signal throughout your home.Why is this amp's "two-way" or "bi-directional" feature important? A two-way feed is necessary in order to support a cable modem (upload/download) and to support interactive cable services such as PPV (pay per view).This amp won't work miracles.
I moved into a new home which had seven cable outlets in different rooms. One of the bedrooms I turned into an office but the problem was that I only had one cable connection in the room. The connection did okay with either the cable modem or the HDTV but not with both connected. The cable modem would not connect with the TV connected to a splitter. I connected the amplifier and ran one cable to the TV and the other to the cable modem. I crossed my fingers and plugged it in... Now I have a great cable internet AND HDTV signal, both from one cable connection.
Answer: Yes but it will not make your internet faster!
