The CAT01 is designed to distribute HD & SD television signal (RF) over Cat 5e/6 cable. High frequency RF baluns in both the CAT01 and KLE02 leads (end converter) convert RF signals from a 75 Ohm coaxial input signal to a 100 Ohm UTP signal and back to RF again by the KLE02 lead at the end point. The amplifier has four separate RJ45 outputs each with an individual gain control. The amplifier also has an overall gain and tilt control.
