This Dual Port Tap with One Port Power Pass (sometimes called directional, couplers, taps, drop taps, or tappers) operates to extract a portion of a CATV signal coming from a distribution cable to feed a subscriber’s tap, all while maintaining the proper characteristic impedance from the distribution cable.
