EXTREMEtenna August 24, 2016
Reviewer: Greg from Phoenix, AZ  
I've had the EXTREMEtenna for about two weeks and it works great! I'm receiving 75-80 channels compared to the 40 I used to get. Excellent product / Excellent price! Way to go Channel Master!!!

Extremetenna 80 August 24, 2016
Reviewer: Anonymous Person from Colorado Foothills  
After giving up on a smaller antenna that advertised 150 mile radius due to the fact that each channel came and went too much, we tried the Extremetenna 80.  We picked up the ones we previously had but are able to keep them on continuously and we picked up a few weaker ones that we can count on 90-95% of the time.  We just haven't seen how well the unit will do in snow storms as of yet, but we're generally pleased.

CM4228HD very good August 24, 2016
Reviewer: Bill from SWFL  
CM4228HD works very well in our location. We had a smaller RCA but it would only pick up channels in one direction. The CM4228HD receives channels that are 45-60 miles north. It also receives channels that are 30 -45 miles to the south. West coast Florida is flat. Our antenna is mounted to the former dish mount with 5 feet of pipe added. We have a distribution amplifier. Our antenna received 65 channels but we deleted the unwanted channels and get 45 perfectly watchable channels. Thunderstorms do affect reception but we can choose channels from the opposite direction to combat this. No rotator is used.

CM 4228HD August 24, 2016
Reviewer: Lee from White Bear Lake, MN.  
I am committed to free TV and to an antenna mounted in the attic.  I have tried 4 previous antennas and all have ranged from terrible to fairly good.  A few weeks ago I gave it one more try and installed the 4228 8 button CM antenna. The antenna came assembled, it was reasonably easy to install, and when done with the installation I pointed the antenna in the general direction of the towers and headed down to where it counts, in front of the television (s).  Finally, clear reception on all channels available.  I have not been back in the attic to 'fine tune' the antenna because it seems not to require that detail.  Why didn't I make this move years ago.  This product has taken 'TV antenna fix' off my to do list, finally! Thank you.

Television signal reception anomalies August 24, 2016
Reviewer: Russ from Wichita, Kansas  
Cutting the cable was the best thing I've done. Getting a good clean signal has been a challenge. After installing the LTE filter, the AMPIFY, and the EXTREMEtenna, I think I'm there. In spite of all this, on occasion I still get what I believe is LTE garbage. I even relocated my antenna to be sure of a clean line-of-sight path for reception.
Basically......I'm happy!
