Orbital Thru Tee (Bias Tee Thruplexer) The Orbital Thru Tee (TT-25/40) is a bias tee "thruplexer" that passes both L-band and 10 MHz signals between your modem and low noise block downconverter (LNB) or block upconverter (BUC) - in addition to inserting an external DC power source of up to 4.0 amps. The Thru Tee uses internal filters to block DC from the modem and minimize 10 MHz noise - delivering extremely low thru loss and very high return loss. Primarily designed for the satellite communications industry, the Orbital Thru Tee is also a good fit for 4G and 5G cellular networks. • Filters L-band/10 MHz signals and inserts DC • Choice of connectors and mounting options • Customizable form factor • Stackable with other Orbital products This product often used to allow insertion of DC voltage where the indoor modem/equipment either has no ability to provide DC on its IF Receive interface or cannot provide sufficient power for the outdoor LNB/BUC.
