    Works when needed but is probably unnecessary

    Worked when I needed it to but became obsolete when we got our ISP out to replace the lines. Now it overloads the system if I try to plug it in. I keep it on hand in case we ever run into issues though.

    We watch over the air tv ( no cable). Every week, for some strange reason, we would lose the signal. We are about 70 miles outside Boston. We purchased this amplifier. Plugged it in , and have a much more reliable signal. I think we lost the signal on one channel once for a few minutes. Other than that we get 28 great channels. NBC, ABC, CBS, PBS, FOX, and some independent Chanel's . Unit is easy to install. Takes about ten minutes.

    With this device I was able to get more channels and better picture quality. The cable from the antennae to TV is over 100 ft so when I replaces the regular splitter with the Rocketfish amplifier I got more channels on each TV plus a sharper picture.

    Splitting made Easy

    I started using to split an outdoor antennae into a few different rooms into the home when "cutting the cable". Not only was it easy to set up but the signal enhancer did work better than I thought (have had issues with losing quality with signal after splitting into multiple TVs). The only issue I've had is the AC adapter, it's a bit flimsy and consider most cables come into the house in an out of the way place (like mine) where there may not be outlets it could be longer.

    Look I know with todays TVs everyone thinks HDMI is there best way to hook up extra components to the TV. But there are some people that maybe still have VSH players or old gaming consoles or maybe satellite receiver that is still good working condition or maybe you still have cable. Here is the problem all TVs either newer or the old CRT models only come with 1 VSH input. This is where you need coaxial splitter. Rocketfish Mini Drop Amplifier works great and picture lose or distortion of any kind is not there. It is very well made and I highly recommend to everyone.

    I purchased this amplifier to compliment the new antenna I put in the attic. The cable was feeding a TV 2 stories down in the basement. Before I put this on, I was not getting very many stations and those that came in were poor picture quality. After I connected the amplifier, I got 20 local station, all coming in crystal clear! I could not be more satisfied!

    Cable comes in to the house and splits to multiple units - modem and several televisions. This unit amplifies the signal so that it is actually stronger after the split than before. Digital TV sometimes went blotchy/stuttery before I got this. Since I installed this, pure picture all the time.

    You need this. It boosts the signal from the antenna to your tv's. I have 3 tv's using one "HD over the air" antenna in my attic with no issues. After hooking it up and re scanning the channel list on each tv, i picked up 8-12 channels i didn't get before on each one. Gotta put it close to an outlet so you can plug it in.

    I was adding an outside TV with my Cable Company, and it kept losing the signal. That was a total of 4 televisions , and I needed to boost my signal for better picture quality.. This hooked up easily, and has a light to tell you its working. All my TVs get a solid feed ,and no issues whatsoever.. Great Product.

    I had lots of problems with reception at my house, mostly due to the trains that run not far from my house. Now I can actually watch an entire tv show without interruption. Another plus is that it's really easy to hook up, it's just like hooking up a splitter except it plugs into the wall.
