5 of 5 You have to get this antenna October 8, 2020
Reviewer: Joe from Blackheath Ontario Canada  
Just installed on 30 foot tower with rotator. I am out in the country with flat land. I am near Blackheath Ontario Canada. Close to Buffalo and south lake Erie. I am getting 48 channels. I am getting stations in Erie PA. Getting stations 124 km away with medium signal. No preamp at all. If you want an excellent antenna for distance then buy this. Worth every penny. It is a huge antenna so make sure you have room when installing. Highly recommend this.

5 of 5 Classic August 10, 2020
Reviewer: Jimmy from Newton Grove NC  
These were remarkable &built to last forever they are incredibly heavy extra effort needs to be taken when you attempt to install one. I dont believe Their Rotators will handle the weight of this antenna, if they bring back the CM 3679 model its smaller
