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.
