Long cable runs March 27, 2019
Reviewer: Smitty from Illinois  
I used this combined with a pre amp at the antenna since I have very long cable runs with the cheap RG-59 cable inside my walls. I am getting every channel in my market even though it took almost 80' of cable just to get the signal down to my basement and then all the way back up to my third story finished attic.

I am very satisfied with all my Channel Master products.

Exactly what I needed February 11, 2019
Reviewer: Gerry from KY  
I am in the process of cutting the cable. This 8 port distribution amp is working well. I did not have a spare cable to run from the power supply to the unit so I used a power inserter on the proper port to supply power.  I just purchased another unit as a spare.

Excellent product! Solved my signal issues. February 11, 2019
Reviewer: Chris.M from Whiting, NJ  
I have the extremtenna 80 and the amplify pre amp but was having signal issues on my long coax runs. The distribution amp has solved all of our issues and even allowed us to receive four more channels we didn't know we could get. As usual this unit is of high quality like the rest of the Channel Master product line.
