      It Worked, But...

      It didn't help my situation enough, so I returned it. Many reviews I read here gave me some false hope that this amplifier would boost my signal, and it did--- insignificantly. That's not the fault of the device, though. The product descriptions for these devices are nowhere near sufficiently detailed. The truth is, getting great reception from a digital antenna entails quite a learning curve, as well as much trial and error. This device is a DISTRIBUTION amplifier. When you use a splitter to distribute your signal to multiple rooms and TVs/devices, it weakens the signal traveling down each cable. This amplifier will boost the signal before splitting it off to different places. THAT is what it's designed to do. In that right, it worked for me. However, my need was different. In my situation, the signal was a bit weak when it hit my rooftop antenna (a decent model, but it had no amplifier built in). Then the weak signal traveled through 60 feel of wire, which weakened it further, when it reached the Rocketfish amplifier. All the poor thing could do was to boost an already lousy signal. It helped, but not enough. I needed to boost the signal as the outdoor antenna first received it-- at the top of the mast. So I returned the Rocketfish and purchased a Winegard Boost XT, model LNA-200. That one did the trick. I went from 29 channels (some weak) to 50! So-if you have a good signal from your antenna and need to send it to several places, try this Mini Drop (--talk about a techie, vague, useless name!) amplifier. On the other hand, if you live 10-25 miles from the local transmitters like I do, amplify the antenna itself. I'd recommend this product only IF your situation requires a distribution amplifier. But for goodness sake, buy locally and SAVE YOUR RECEIPTS! I returned several items that turned out not to be what I needed.

      I finally cut the cord with comcast. I already had a Roku TV so I have been wanting to dump my cable TV and the cost. My first step was to use the Best Buy offer for Sling TV and that provided a free Roku 2 for a second TV. Now I live about 30 miles outside of Pittsburgh where the local channels are located. If you know anything about the Pittsburgh area it has hills and trees! I picked up a Clearview 2 OTA antenna. Set it up on the ridge of the house and hooked it up to the existing cable. Local stations were in HD however when I went to split the signal it would pix-elate if there was more than one TV. (2 way splitter). Read and searched regarding antenna amps, pre amps, etc. Came across this and decided to try it and I could not be happier. Now I have 4 TV's with perfect signal and picture, even our local NBC. Remember this is not an antenna preamp so it will not amp the antenna. The antenna will still have to have an adequate signal strength. This amp compensate for the signal loss from the lengths of cable and the splitter. So the antenna is on the outside of the house, ran cable to the inside of the basement (40 feet) then to the Rocketfish. All of my cables to each individual rooms then connected to the out of the amp. Lastly it was such a good day to take all my equipment to Comcast and cancel my cable!

      I have Comcast for Phone, Internet and TV. For whatever reason, Comcast can't get me a strong enough signal from the new pole across the street, even though I had a perfect signal with the old pole 3 houses down before they rerouted my feed. In order to "accommodate" the needs, they installed a "compensating filter" that improved my phone and Internet signal at the cost of having "no signal" 80% of the time on the TV. If you amp the main input from the DMARC, everything purrs. Everything works. Unfortunately, when the power goes out, the phones go down too because this amp doesn't pass any signals without being powered. (I thought it would be like 1990's amps that were dumb splitters when unpowered and boosters when powered, but I was wrong.) If you amp the low side of the compensating filter, the TV now works about 80% of the time and the phone and Internet are as good as before. If you amp the TV side after placing a regular splitter instead of a compensating filter, the TV is perfect, but phone and Internet occasionally drop out. The short answer is that Comcast is the problem, not the amp. If I had my data rack finished, I'd have a battery backup anyway, so powering the amp would be trivial. Given a rearrangement of equipment, I should see better results yet by placing the phone on the outside of the amp and moving the Internet to the powered side of the amp, so I can eliminate the compensating filter and reduce the db of loss because of the double split Comcast installed. (DMARC to 2 way - 1 to TV splitter, 1 to phone / Internet splitter)

      Performs Exceptionally Well

      My parents recently added a cable box so they could receive additional HD channels. Unfortunately, many of the channels were not coming in and others were pixelated. I figured this was because the multiple splits in their cable had reduced the signal strength. I replaced a four way splitter they had previously installed with this booster. The location of the booster is near where the cable enters the home, which is recommended. The booster then sends the signal to a four way splitter, two two way splitters, and one cable running directly to another TV. The cable box now works perfectly. They also have two other HD televisions. After performing a rescan, they now receive additional channels that they didn't realize they had. Apparently, the signal had been too weak for the TVs to pick up the channels. This booster also has bidirectinal capability which enables signals to be sent back through the device to the cable company. Prior to the booster installation, their On Demand was not functioning at all. However, after installing the device, their On Demand and Cable Modem function perfectly. I would highly recommend this product to anyone dealing with a weak cable signal.

      Good, but analyze your needs first.

      This item was ultimately returned as it was not powerful enough to meet our needs. I used this to amplify a UHF/VHF digital antenna signal over 60 feet of quad-shield RG6 cable from the roof and then out to three separate TVs over another 75 feet of cable for each TV. This unit does what it promises but the cable length and mutiple TV needs overwhelmed its capacity. I ultimately got a more powerful two-stage amplifier that's mounted on the roof antenna post. Power is send from the basement up to the amplifer where it boosts the signal at the source. TVs now get a few extra channels and better reception. I recommend analyzing what your needs are first and then determining if this is going to be strong enough for you.

      Good amp but not great

      This amp is OK but if I had time, I'd order a Channel Master online. It provides about 10dB of gain and has a built in 4-port splitter. So if you replaced a 4-port splitter with this, you'd get 10dB of gain. That allows you to run a little over 100' of RG-6 on each output. My tests showed about 3.5dB of gain even though the unit is marked 4dB. The paperwork that comes with it says that it's noise figure is 7.5dB which is extremely high for a 10dB amp. It accepts power over the #1 output but there isn't a power inserter included with the unit. That would have been nice because there's rarely an outlet wherever you want to stick an amp. The included wall wart's cord is 6' long.

      I purchased this item as an open box item. It included all the original items. I needed a little bit of a signal boost on a cable run I was using for cable tv. The cable line comes into the house hits 1 splitter then goes up a floor to another splitter and terminates in a room at the cable box. This run is around 100 feet. The cable box would get most channels in ok but specific ones would not come in at all or would come in choppy. After replacing the first splitter with the purchased amplifier and using the power adapter, I was able to get all the channels in correctly that were either choppy or missing from before. So I would recommend this item for anyone that needs a little extra signal boost on a long cable run.

      Too many coax splits in the house had resulted in a poor HDTV signal at one of our TVs. I had already used a similar product at the first split and wanted another for the second split in the attic. Based on the picture and description, it appeared to be ideal for the attic (no power nearby) since it can be powered by "power insertion" where power is back-fed by coax from a downstream outlet. Unfortunately (unlike the similar product I already had), it does not actually provide a power inserter, just says you can power it that way if you have a device capable of providing power via coax. So not suitable for my intended use (but I made do by putting this at the first split where power was available and then putting my older splitter/amp (which did include a power inserter) in the attic). However, once I reconfigured, I now have excellent signal at the TV that was having problems.
