Orbital TT-25/40 VSAT Thru Tee with 10 MHz pass-through
Thru Tee is specifically designed for sensitive satellite applications with the ability to let both the L band signal and the 10 MHz reference pass through.
TT-25/40 VSAT Thru-Tee
The Orbital VSAT TT-25/40 Thru-Tee introduces a System Interface Device (SID) that can be used as a 10 MHz pass-through. The Through Tee passes the 10 MHz as well as the L-band signal while you insert DC power, and it has a spare 10 MHz port to monitor the reference signal.
Standard Bias Tees are not designed for Satellite applications. They are very simple circuits, and will short the 10 MHz to ground
Thru Tee is specifically designed for sensitive satellite applications with the ability to let both the L band signal and the 10
MHz reference pass through. As they age, satellites and BUCs lose power. The VSAT that once served you well now does not have enough power for your link budget and the BUC just got passed to you! The two solutions are a bigger dish, or a bigger BUC. The new BUC is cheaper and faster to install than a new dish, but your modem cannot supply the higher current needed by the new BUC. You need an independent, high quality power supply.
You get a Bias Tee to inject the power into the L band line to the BUC, but guess what, the 10 MHz reference signal from the modem is now shorted to AC ground via the power supply. You need a special Bias Tee that will allow the 10 MHz reference from the modem to the BUC. Welcome to the TT25/40 - Thru Tee. The Thru Tee replaces Orbital's MT25/40 - Mux Tee L band filter with a filtered 10 MHz bandpass and a filtered L band, 900-2100 MHz selective band pass system that will allow injection of up to 4 amps at 12 to 48 VDC, and will pass the L band signal AND the 10MHz reference signal from the modem to the BUC with less than a single dB of insertion loss.

Professional Satellite
Interface Products are made specifically for the satellite industry, and are designed for professional and industrial quality systems. VSAT System Interface Products are built for rack mounting, and for use indoors or out. They are also perfect at the dish or in the rack for creating a test point for live signals - without degrading ongoing operations.
Built for indoor mounting back-o-rack, but its 'O' ring sealed connectors and corrosion protection due to its Allodyne finish, also allow for outdoor use.
