Electroline EDA 2100 1-port RF/CATV Amplifier Review

Electroline EDA 2100 1-port RF/CATV Amplifier
Average Reviews:

(More customer reviews)
Been using this for several days now, just one of many drop amps I've tried over the years. It has good contrast, low noise, and smooth, even transmission across the full spectrum of analog and digital channels -- as opposed to several amps that vary in clarity between low-band and high-band channels. It certainly beats competitive products from Motorola, Radio Shack (no surprise!), and the noisy PCT amp with its reddish color balance. The only area in which it doesn't excel is that it lacks a subtle snap and sparkle that I had with my old PDI drop amp -- but that amp's 7 years old and showing its age. It seems to have a softer image than the PCT or PDI. But this is a relative judgment, and most of its competitors don't come close to its clarity of image and clean color. No drop amp is perfect. This one seems worth the few extra bucks. Take some care, though: 15db is more power than many people need. I'm using it with two 2-way and one 3-way splitter down the line, with a total loss of -12.5 db on my line. Thus I actually have about 2.5 db more power than I really need, so many people might consider a 10 or 11db amp as more appropriate. In my case I inserted 3db of Antronix line resistance to avoid overloading my tv and recorders. If it weren't for that slight difference in sharpness and sparkle, I'd have given this 5 stars instead of 4. But most people won't see the difference. For sure, I'd recommend this drop amp over any others at Amazon now in the under-$100 range.

2-Port Bi-Directional Cable TV HDTV Amplifier Splitter Signal Booster with Passive Return Path Review

I have a couple of the PCT Amplifier in my set up. They do a great job of keeping the DTV signals strong. I have one station that is 90 degrees from the other stations that with out a distribution amp, the signal degrades to the point where I'm lucky to get 20-30%. With these amps, i'm getting 80-85% signal. I'm also occationally getting out of market stations that I was not getting without them.
To be clear, these help keep the signal from degrading along the long runs from the antenna to the tv/reciever - they are not boosting the antenna power.

Motorola Signal Booster 1-Port Cable Modem TV HDTV Amplifier with Active Return Cable Modem Boost Review

Motorola Signal Booster 1-Port Cable Modem TV HDTV Amplifier with Active Return Cable Modem Boost
Average Reviews:

(More customer reviews)
The product details don't make it clear that this is the product is actually the "BDA-K1/PS/RA" which means it includes a power supply. No coax cables are provided, and you will need at least one to connect the power supply, as well as another to connect the amp wherever you are inserting it in your system (typically as early as possible where the cable enters your premises).
The warning about not using an active return amp unless your upstream signal level is above 50dBmV is an ok rule of thumb; I would probably suggest that if you are above 45dBmV then it may be worthwhile. However, you should also be concerned about the downstream power level since equipments' tolerance for downstream power is typically much narrower (e.g., -12 to +12dBmV) and this amp gives a +15dBmV boost. You should not use this amp unless the downstream power level is less than -3dBmV.
Also, it may be a problem in your dwelling that different branches have different numbers of splits and, while the amp brings one branch into balance, another branch gets taken out of the optimum range. In that case, you can buy attenuators like In-Line Attenuator 3 dB to bring down the power levels on such a branch.

I have a new house with very long cable runs. When they built the house they ran a seperate cable to each room, instead of splitting them upstairs in the attic. I had an issue with the digital cable and the modem loosing signal and picture freezing before I purchased this item. It took about 5 minutes to install the amp and all picture issues are gone. Before I could not have the signal split into more than 3 lines before experiencing picture issues. I now have 7 lines running out of the amp without issue, including the cable modem. Great product, and you can not beat the price.

Electroline EDA FT08100 8-port TV Signal Booster/Amplifier with Active Return Path Review

Electroline EDA FT08100 8-port TV Signal Booster/Amplifier with Active Return Path
Average Reviews:

(More customer reviews)
I purchased this unit because I have two analog feeds and two QAM digital capture feeds (via an HDHR unit) that I use in conjunction with SageTV for recording television. I also have a cable modem so there's a couple splitters involved. I did purchase good passive splitters (Monster 2 and 3 ways), however the QAM signal quality levels and the modem performance were not ideal.
I got this model because of the cable modem support. Imagine my surprise when the first thing to pop out of the box is a note from the manufacturer that it's best to put your cable modem on it's own line off a splitter and not hook it up to this unit because some signal loss may occur. What the..?!?!? After ranting for a while and generally annoying my wife with my whining I hooked it up anyway and took some measurements. Fortunately their warnings are not necessary - they may want to think about rewording that little note a pinch.
Here's the hard numbers:
The QAM capture signal strength using a Monster 3 way split off the single line coming in my house (I have no up stream splitters - it's all centralized in closet) for the HD ABC feed had a strength of 88 and a signal quality of 92. Putting the one line as the feed into the 8 port amplifier and running the QAM ports off of it the strength jumped to 92 and the signal quality hovered around 94. Nice. Doesn't sound like a huge deal but for HD QAM captures it makes a difference.
I didn't notice any different before or after with the analog channels - I wasn't having a problem with those.
The cable modem was the item I worried about. Downstream from the splitters it was pretty bad - anything would be an improvement. With the outside cable plugged into the Motorola modem directly downstream signal to noise ratio was 38.6 dB (higher is better, anything over 30 and you're aces), the down stream power is .2 dBmV (fine) and the upstream power was 42 dB (anything less than 50 and you're fine). After running it through the 8 port amp the downstream noise ratio was 38.3, down stream power 1.7 and the upstream power stayed at 42. All dandy numbers. I checked the speeds at several sites before and after and they all averaged about 10 meg down and 1.5 meg up across the boards - virtually no difference. Just about exactly as good as a direct connection and much better than down stream from a passive splittler, even a good one.
So - short version I'm extremely happy with the purchase but I'd suggest to the fine folks at Electroline that they rethink their warning note in their box so as not to tick folks off too quickly for no reason.

CE LABS 6001 Prograde 1 GHz Bi-Directional RF Amplifier Review

CE LABS 6001 Prograde 1 GHz Bi-Directional RF Amplifier
Average Reviews:

(More customer reviews)
I am using this for my CATV that has three splitters after it. The incoming signal was not very strong and after the third splitter, the picture was terrible on one tv. After installing the RF amp, it was beautiful. The CE 6001 has 20 db of gain (more than most other RF amps). I ended up turning the gain down a little (a very useful feature although you need a very small screwdriver to do it) to be sure it did not overload the front end of my tv off the first splitter. I had an RS version (15-2505) previously and it did ok but added a little noise on the weakest signals. That was all plastic and certainly not weatherproof. In contrast, the CE 6001 is a nice, sturdy sealed aluminum case and I could not see any evidence of additional noise on even the weakest channels.

Open House H816BID 1 X 6 Powered Video Amp Review

Open House H816BID 1 X 6 Powered Video Amp
Average Reviews:

(More customer reviews)
Once I plugged this in, I noticed a definite improvement on my analog cable signal (signal that doesn't come through a box). And since that was my greatest concern, I would have been happy there. But I also noticed a significant difference with how digital and HD looked afterward as well. What I noticed most was the lack of 'blockiness' that tends to occur with fast moving video images. While there is still some, I think this device eliminated any blockiness that existed due to the signal being split out.
I cannot speak to the long cable runs as my longest run is only about 50 feet, but that run does look great.
My only hangup is that it's pretty clear the manufacturer wants you to use their utility boxes for wiring. Anything else will require some imagination. So if you keep all your RG6/cat5 hubs in a cabinet, you may find this a little frustrating to mount.
Otherwise a great piece of equipment.

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!

4 PORT CABLE TV / HDTV / DIGITAL AMPLIFIER INTERNET MODEM SIGNAL BOOSTER INTERNET AMP Review

4 PORT CABLE TV / HDTV / DIGITAL AMPLIFIER INTERNET MODEM SIGNAL BOOSTER INTERNET AMP
Average Reviews:

(More customer reviews)
I'm very happy with this device. Looking at the reviews, I think those who are unhappy with it do not understand what it does:
An amplifier like this is not a magic box that will convert an unusable signal (say from a digital TV antenna) into a usable signal; rather it solves a very specific problem.
Suppose you have an signal that is usable at the point of the antenna, but is NOT usable at the point where you want to use it. This might be because you have a long run of coax cable between the antenna and your TV/converter box/tuner/whatever; or it might be because you want to split the signal to feed it into multiple TV/tuner boxes/etc. If this is you situation, the device works very well.
If your problem is that your signal is too weak to be useful directly at the point it comes out the antenna, even before it goes through any long runs of coax or splitters, then no amplifier in the world is going to help you out. What you need is to acquire a better signal. Depending on your circumstances, this might be done by
- changing the angle/orientation of your antenna
- moving it around the room (so it's nearer windows or away from metal or whatever)
- moving it higher (if necessary going outside the house and onto the roof)
- or getting a larger antenna with a larger collecting area.

Motorola Signal Booster 2-Port BDA-S2 Cable Modem TV HDTV Amplifier Review

Motorola Signal Booster 2-Port BDA-S2 Cable Modem TV HDTV Amplifier
Average Reviews:

(More customer reviews)
This is the 2-port version of the Motorola Signal Booster, combining that product's excellent 15 dB cable/antenna drop amplifier with a 2-port splitter so you can use it with both a digital cable (HDTV) signal and a cable modem without having to buy a separate splitter.
So who needs one of these things? Anyone who is having difficulty receiving a consistent cable TV or cable modem signal is a candidate for this amp, but first check with your cable company to confirm that they have done all they can, in terms of getting high quality cables and splitters into your home. If they've done that, and you still notice frequent outages of your cable internet service, or pixelated (distorted) images on live or recorded TV shows from cable, then you may very well need a drop amp like this one.
The 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). Any time 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. 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. Again, always check your incoming signal, cable and connector quality first. But if you've done all that and are still having trouble, this little cable signal amp can be a real life-saver. It also works fine for OTA (over the air) HDTV signal distribution, but only if you're starting with a decent quality signal to begin with. A full review of the Motorola Signal Booster is available on Big Picture Big Sound's web site.

This Drop Amp works great! I have a two story home with a several TV's at the far end of the house that never had clear pictures. They have always been grainy and just never looked right. Well after talking with the cable company they told me they could come out and put an amp on the cable to boost the signal and it would cost me a service fee plus the cost of the amp which would be a total of $150 bucks. I would have thought they should have fixed it for nothing. Luckily I talked with a friend of mine who had once worked for a cable company and he told me that I could get an amp myself and recommended one of these. So I bought one and installed it myself! It took maybe ten minutes to get this thing up and running! I also found "thanks to the cable company" they had extra splitters in my cable run in the attic that was not needed "this will also degrade your signal". Now my TVs have clear pictures and look great all for $35 bucks!

Average Reviews:

I'm not sure where these '0ne star' folks live but I suspect they are way-out in the boonies. Before mounting the Wingman on my RV antenna I was able to receive all the local Sacramento, CA stations just fine. But I travel where there are poor reception areas. So I installed the Wingman. After installation, parked in the drive way, I now also get many of the San Francisco stations 80+ air miles away.
Installation. The guy with issues on installation should have looked at where his antenna was located first before buying and item that won't fit in the space available. That's not a Winegard issue, thats a failure to plan ahead before buying. I INSTALLED MINE IN LESS THAN 10 MINUTES.
GOOD JOB WINEGARD. YES I RECOMMEND THIS UNIT.

Just purchased this at radio shack for $32 plus tax... Install it as close as you can to the external box for your cable (you want to amplify the best signal you can for your entire system, placement closest to point of origin is best), turn it to highest amplification and plug it in...
I could not receive channels above 600 consistently, and my lower band channels that are not digital and had poor reception for my HDTV became vibrant again.
Absolute bargain, it works, it is easy to install... what can I say? Others have noted that it is far smarter to install an amp than to call the cable company out and have them spend hours trying to find where the loss of signal is (having done this in the past, I agree!!)
