Signal directional coupler(UBDC-1109L)
L-type Directional Couplers with flat F ports is for easy cable connections. The L-type housing is perfect for in-wall installations where dimensions have been minimized by removing the mounting tabs.
Signal directional coupler are typically used in conjunction with a wall plate.
Sealed ports to prevent moisture ingress to 15 PSI. Flat 15 psi Sealed, SCTE Compliant F-Ports Prevents water migration, while meeting SCTE standards.
6 kV Ring Wave Surge Protected All ports are protected against multiple 6 kV ring wave surges per IEEE specification C62.41 Category A3.
75Ω Nominal Impedance.
