5 of 5 Excellent! April 6, 2020
Reviewer: B from Carmel, IN  
Couldn’t be happier with the 4221.  It's mounted in our attic over the garage, so it’s on the second story level.  Pointed to most of the TV transmitter towers in town, and the 4221 supplies more than enough signal strength to six TVs in our home, three of which are on the end of a long coax run to the basement.   All of this without needing an amplifier.  10 decibels of gain really does it for us and our TVs.

5 of 5 Finally cable free December 28, 2019
Reviewer: Wayne from Vine Grove, KY  
Just installed this antenna and the preamp that comes in the bundle in the attic of a one story home for a friend that got tired of paying for cable. The home also sits behind a hill, but even on the cloudy rainy day that I installed it we were able to receive all 55 channels that antennaweb.org listed as receivable channels. A few were a bit pixelated, but not the big 4; ABC, CBS, FOX, and NBC and supplemental channels that they broadcast. The CW also clear. I assume on a clear day that there will be no pixilation at all as the pixilation was only minor.
Disclaimer: I do not have this antenna mounted in my house; I am still using an 18' antenna that predates digital OTA broadcasting and get all the same channels. I tried the Lava HD 2605, but it did not receive as many channels as my old giant.
I highly recommend Channel Master over any other brand.

5 of 5 Outstanding product! July 30, 2018
Reviewer: Jeff from Murfreesboro, TN  
I installed my new antenna last week.  I am very impressed with its ability to pull in local stations.  I installed it at ground level on a post that was previously used for a DISH receiver.  The installation was easy for me. The instruction manual was only so-so; therefore, I studied the clamp-bracket assembly and I figured it out on my own. Even at ground level I get very good reception of at least 80% signal strength.  I paid only $69 including the shipping.

5 of 5 Excellent Quality June 5, 2018
Reviewer: Anonymous Person from Cary NC  
I originally purchased an RCA omni directional flat panel outdoor antenna and had it mounted on my former DirecTV dish mount so it could feed my existing cabling.  I got average results.  Weather, wind and air planes really disrupted my signal.  I had a guy come out and replace that with the Channel Master 4 bay and now the quality is nearly perfect all the time, even with weather and air planes going over head.  He also installed a distribution amp in front of my splitter. 4 TVs all local channels.  Use DirecTV now for ESPN etc since I get that for $10/month as an AT&T wireless customer.  The HD quality is stellar.
