If it's not watchable, then add a pre-amplifier between the antenna and the 100ft coaxial cable segment to compensate for the attenuation. It picks up stations from all over the region and has very little static. Me and some of my friends, believe we should cut the coaxial cable in a specific length, determined by the wavelength multiplied by VF ( Lcoax = (300 / F) * VF in meters). The coax cable connects and delivers videos and audio signals to the television. The TV in the basement gets spotty reception.
