Attic use December 27, 2016
Reviewer: Henry from Chesapeake Va  
Using CM4221HD in my attic in a fixed position.  Great reception (better than the Mohu Leaf 50 it replaced).  Arrived with a couple of bent reflectors and bowties that were easily straightened by hand.  Super easy assembly and mounting (used 4' length of 1 1/4" id PVC pipe mounted vertically).  The included mounting bracket fit very nicely and held the antenna securely in position.  Picked up 44 stations on first scan, including CBS, NBC, ABC, PBS, FOX, CW, MYTV, & ION.  Picture is crystal clear with no pixelation or compression artifacts.  TiVo Roamio OTA 1tb for recording.  Using streaming services HULU, Netflix, amazon Prime and Sling on ROKU.  We'll get rid of some of these after a while.  Cable TV was $153 before and we were not satisfied.  TV & streaming now is 1/3 the cable cost (will go down).  With a good antenna (like the CM 4221 HD) and streaming services you can cut cable tv and still have a better viewing selection for much less money.  We should have done this years ago.

ULTRAtenna November 11, 2016
Reviewer: Randall from Mesquite, Texas  
I live in a suburb East of Dallas, Texas with major broadcast towers in Dallas and South West of Dallas.  I aimed the  ULTRAtenna directly at the broadcast tower South West of Dallas and to my surprise was able to receive 113 Digital channels and 2 analog channels which  included the channels from the Dallas broadcast antennas. All channels are clear and the audio is distortion free.  I'm very pleased with my purchase.

Works as expected and then some November 11, 2016
Reviewer: Anonymous Person from Central New Jersey  
I replaced a so-called omni-directional active antenna with the ULTRAtenna and am quite pleased. I receive all the stations I expected to and each has a clear, solid signal. Since I am close to and LOS from New York City even Low VHF and many FM signals, technically out of the antenna bandwidth, are received at impressive levels.

Reviewer: Steve from Minn  
This is the second one that I have purchased. This one was for my mom. These have performed very well over a 30 mile range.
