### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    For Cord Cutters
  

*by K***N on Reviewed in the United States on January 22, 2016*

I purchased this device to improve the signal strength of fringe or low power TV stations. As an example with a TiVo TCD746320 DVR, wired to an attic mounted GE 24792 antenna, the relative signal strength on a distant station went from 35 to 43 which eliminated TV pixelization.  This amplifier also helped to increase the signal strength resulting from the loss associated with splitters (typically -3.5 dB / port for a two way). And, in some cases will provide for a substitute for a splitter.  A nice feature of this amplifier is that it can be phantom powered. In other words one of the RF outputs is shared with the included 15VDC power supply on the same coaxial cable.  You will need the EDA-1CF Remote Power Inserter (not provided) to isolate the two.  This allows the amplifier to be located in an area that makes powering difficult to obtain.  What's interesting, is that the blister package that the amplifier / wall wart comes in, has a cavity for the EDA-1CF Remote Power Inserter, but it's not included. A major concern is that amplifiers can have too much gain and can overload TV / DVR inputs caused by nearby TV stations.  This amplifier did not do this.As a precaution, a 75 ohm terminator should be used on all unused ports.I am very pleased with its performance and it does the job well...My only complaint, is that Electoline's technical support is not very helpful.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works perfectly!
  

*by J***R on Reviewed in the United States on September 28, 2015*

Works as advertised. It's not *real* clear anywhere else on the page, but if you are using a power inserter downstream, this splitter allows you to use one of the outputs (labeled "out+pwr") as a power input. It seems obvious but I had to know before I bought it.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Very good
  

*by A***R on Reviewed in the United States on August 8, 2016*

Its a good amplifier with a good price. Thanks
