Great performance August 30, 2016
Reviewer: Andy from Beaufort SC  
Extremetenna 80 is pulling in stations with clarity not experienced with several other brand and style antennas. I compared 2 against each other in very systematic method documenting each for signal strength over location, orientation and time of day.  We live on flat SC coast with Charleston and Savannah towers about 67 and 48 miles respectively and at 180 degrees apart.  Net result is 26 consistent  stations.  Unit is mast mounted about 18 feet off ground, adjacent metal roof, no amp and very good grounding.  We hauled back our $120/month cable gear and are back on FTA.  Thanks Channel Master!

Knowing the Channel Master name and that they are not new to the business I didn't hesitate in buying their product. It meets even exceeds my needs for good tv signal and reception. Quality of picture even improved. Channel Master is a respected company with many years of experience in building top quality products. MADE IN USA

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.
