Terminator 75 OHM F Port Screw-ON ACDC Blocking 5-2300MHZ - 10 Pack

ACTIVE (requiring power to operate) & PASSIVE (no powering require) RF signal splitting & amplfing devices often requires the installation of a SCREW-ON 75 OHM, AC/DC POWER BLOCKING TERMINATOR on ANY F- PORT that will not have a impedence matching device attached, i.e: coaxial cable. attached. The purpose of the POWERING BLOCK TERMINATOR is to BLOCK any voltages present on the connected cable or device from destroying the fragle resistive load within the terminator.This termination prevent an RF signal from being reflected back from device'F- PORT, causing interference, power & signal losses. The terminator is usually screwed on to the open F-PORT while the terminators center conductor is placed into the center conductor area of the F-PORT's female connector. These F-PORT SCREW-ON Terminators are designed to match the AC impedance of the cable and hence minimize signal reflections, Signal and power losses. Radio frequency signals tend to reflect from discontinuities in the cable such as connectors and couplers, and travel back down the cable toward the source causing interference as primary reflections. Secondary reflections can also occur, allowing interference to persist in introducing errors in data streams, i.e; cable modem signals or QAM based digital video transmissions. These reflections also act as bottlenecks, preventing the signal power from reaching the destination.
