ChannelMaster 4221 UHF antenna September 29, 2016
Reviewer: Kenneth from Pittsfield,Ma  
I tried many indoor antennas,including the mohu Sky.I only got one network and 3 channels(even though the mohu and other websites claimed reception of more.The 4221 with the 4 Bay design, I added a Wineguard preamp flier , mounted inside(I think of it as art like a sculpture) is the only way,excluding a roof mounted antenna that you will receive all the channels that you should without pixelation.

Wish I had 2 of them June 15, 2016
Reviewer: Anonymous Person from Northeast Ohio  
This antenna (with boosters) picks up the "violet" stations about 50-60 miles out.  It is sensitive to direction, though and half of my stations are at 90 degree angles to each other.  I have trouble reaching both sets except on the best of days.

Expectations exceeded for the ULTRAtenna 60 March 23, 2016
Reviewer: ChuckO from Aiken, SC 29803  
I was able to pickup 3 more stations than I anticipated so I am very pleased with this antenna. I was forced to do an attic mount which isn't the best way, and when the wind blows the pine trees hard and the weather isn't cooperating I do get some pixelization on my FOX channel, but overall am pleased with the results and am still looking for the "sweet spot" in the attic. Some notes for newcomers to all this:

Spend time and do your research before you invest. I found this CM website, tvfool, and antennaweb invaluable resources and made the proper selection first time. You can be 5 miles from your TV towers, have an antenna the size of a school bus, and get NOTHING. I've lived it.

it works! January 28, 2016
Reviewer: ward from Watsonville CA  
So rarely does something like this live u[p to it billing but I put it up as directed and without any fine tuning I got all my stations without having to adjust for the different towers. I think the most important thing to say is IT WORKS!! I am pleased that the product does what it said it would do.
