Amp Helped May 22, 2018
Reviewer: Anonymous Person from Greensboro, nc  
Seemed like their amp was the way to go along with their 60 mile antenna. Brought in the majority of my local TV channels much better than the "in the window" HDTV antennas. Seems like a good solid quality built unit but it was very disappointing that Channel Master doesn't have a longer warranty period. For a business that has been in this line of products I would think it would be at least a year or 2. Time will tell on how long this unit will last and if need be where I will get a replacement.

It works April 9, 2018
Reviewer: Jay from Omaha, NE  
I have been looking for a decent 4 way splitter that does not loose signal and this has done the trick and then some. Easy to install. the only thing I did not like is the coax cable to power it.

dividing a weak signal between four TV-sets March 14, 2018
Reviewer: Gary Fisher from San Angelo, TX  
Living in a small market with a challenging array of signals means that this distribution amplifier must share those signals of greatly varying strength evenly with four TV-sets.  Adding to the challenge is an attic antenna which would capture more signal if it were outside.  This distribution amplifier, used in conjunction with the Channel Master Titan-2 r.f. amplifier does the job nicely.  And it is mounted in an attic where the temperatures go from cold in the winter to hot in the summer.  An excellent product for a broad application of situations.
