If you have coaxial cable runs longer than 75 to 100 feet, or if you've split your signal multiple times, you may want to add a signal amplifier to compensate for signal losses. Terk uses premium-grade electronics for the strongest, cleanest signal with maximum gain and ultra-low noise. You get wideband frequency response and true 75 ohm impedance to deliver the best possible signal quality for satellite and broadcast TV and even FM applications.
