4 Port Bi-Directional Cable TV HDTV Digital Amplifier Internet Signal Booster with Bypass Port and Passive Return

Installed this amp in the attic of a friend's two story house along with an unamplified HDTV antenna. The antenna by itself produced a perfect signal on the strongest stations, but on the weaker stations the picture would occasionally freeze or pixelate. With the amp in line, picture freezing does not occur and pixelating is rare. The longest run is about 65 ft to the first floor. Two outputs feed runs of about 45 ft and 25 ft on the second floor. I installed a resistive load on the 4th output. This is a very good product, easy to install, solidly built and sold at a very good price. I installed a second amp in my own house using all four outputs and it works great.

Great product. Our internet signal kept going out. We had technicians from the cable company out but did not help the shoddy signal much. The signal would be ok for a week or so after the tech visit. We switched modems, downgraded service, moved the modem to various locations in the house. Nothing helped...until I installed this system. Installed it about 6 weeks ago and have had perfect signal since. Perfect solution. Very happy with this product. I only give it 4 stars instead of 5 because the instructions are weak and you weirdly have to power it through another coax cable which is not provided.

This review is for the 4 Port Bi-Directional Booster with passive return. This item solved my video freezing problem with Comcast Xfinity. My Xfinity problem I just had Xfinity cable and internet install. I have two televisions. The signal to my primary was good but the video signal to my other TV kept freezing. To fix this, I had to reboot the box and it would only work for 5 minutes before freezing again. This made watching TV completely impossible. I did not want to go thru the frustration of contacting Comcast Customer Support so I decided to see if this booster would work. I've installed it a month ago and I have not had any problems since then. Installation Tips This was easy to install. I replaced the three way splitter with the signal booster. All the ports are label so it is easy knowing what to connect to each port. You will need a two prong outlet and something to ground the booster to. The booster itself has grounding screws on both sides of it. Before you buy this, figure out where you can plug it into and where you can ground it. You do need to supply the grounding wire.

This amplifier works great. My old one from Radio Shack quit leaving the house dark. Replacement was quick and easy. Some analytics: I am about 30 mis west of downtown Chicago. With the old unit I received about 70 signals with the scan by my Sony tv. With the new one the total is about 92-94. At my location the main stations (CBS, NBC, etc.) stations are very strong and I feel the picture is better.

Good signal for all 4 outputs. I am using a yagi at the top of my attic to feed this. Update January 23, 2019: lost several tv stations after the hurricane and I just assumed there were some tower problems. After scanning I didn’t have anything. I bypassed the amp and scanned again then I had 24 dvtv ota channels. It was unplugged before and during the hurricane so I am not sure of the cause. It is mounted outside so a spike could have come through the coax ground. I am contacting to see if they will honor the 2 year warranty shown.

Looked at some other comparable products which seem to be nearly identical, but at a much higher price. This worked great for my garage where I wanted to mount a couple of OTA TVs and connect a DVR. It has 4 normal ports and one labeled ‘modem’ which I am not using. Without this thing I could not have split up the wire without losing the picture. The mounting options are pretty cool, you can pretty much mount it in any orientation with the way the mounting brackets are designed. At less than $15 bucks it is a bargain.

Installed under house because I have some pretty long coax cable runs. Truthfully, almost all the channels I normally get came in already on one of the long runs, but since I was splitting the signal to 4 different outlets, some of them 100 ft or more, I chose this amplifier. 30 foot run from un-amplified antenna to this box, then 4 outlets to the tv's. Very solid build, simple to install. Works just fine. Would have given it 5 stars, but I've only begun to use the unit and reliability doesn't factor into this rating.

Increased signal by 1%. Didn't see much difference for me. Hefty piece of equipment though. Well built.
