Directional Couplers

Directional couplers (also called RF Taps) are used to control RF signal level in a broadband Cable TV network. The RF signal is passed through the directional coupler from the In port to the Out port with minimal signal loss. The signal at the Tap port is reduced by the stated value on the housing (4dB to 30dB).

Typical application of a RF directional coupler in a residence is to place the coupler upstream from the splitter network where it has a direct feed from the service provider. The Tap port is used to feed signal to a cable modem or telephony modem (e-MTA). The Out port is used to pass signal to a splitter network supporting the home's TVs and other audio-video devices.

In a multiple dwelling unit, L-Type directional couplers can be used to create a daisy chain network with a Tap port in each unit. The tap port is fed through a wall plate to create an F-type outlet in the unit.

• L-Type
• T-Type
• Splitter Housing

Regal T-Type directional couplers have a heavy duty mounting tab that allows for positioning at any convenient location. The housing is zinc plated for corrosion resistance in indoor and outdoor installation environments and prohibits water migration. 110dB EMI isolation for environmental protection.

L-Type directional couplers are commonly used in multiple dwelling units. The coupler is installed in a gang box or mounting bracket and the tap port is fed through the center hole of a wall plate. The Regal L-type housing is zinc plated for corrosion resistance in indoor/outdoor applications and is designed to prohibit water migration. 110dB EMI isolation for environmental protection.

The RF Communications directional coupler is conveniently enclosed in a 2 way splitter housing. An integral heavy-duty Ground Block ensures proper grounding, eliminating the need for additional connections and materials.
