Toshiba TV Shared Equipment Bulk item, dead stock, new. Model Number: TUFS-7-7 Specifications: Passable frequency 10-2150MHz (when the switch is set to "bidirectional") For relay (intermediate) use; all terminals are F-type connectors (with threads) Upstream band (10-55MHz) flow noise cut (high-pass) filter built-in (can be switched on/off) Specifications (manufacturer's website) This is a relay TV terminal with a built-in bidirectional/unidirectional switch for blocking upstream flow noise. ● Relay Terminal ● This product has three terminals: "IN", "OUT", and "TV terminal (front)". This is what is commonly called an "intermediate unit" and serves to branch and extract signals from the trunk line. You can split the signal without preparing a separate splitter or brancher. The insertion loss between IN-OUT is approximately 2dB, and the coupling amount between IN and the front TV terminal is approximately 11dB (in the case of 10-770MHz). For example, if an 80dBuV signal enters IN, theoretically, approximately 78dBuV will come out of OUT, and approximately 69dBuV will come out of the front TV terminal. ● Upstream Band Cut Possible ● The upstream band (10-55MHz) cut (high-pass) filter built into the TV terminal side can suppress upstream band noise from TV terminals not used bidirectionally, for each terminal. (Bidirectional signals can pass between IN-OUT regardless of the switch position) Also, by operating the upstream band cut filter switch, you can easily make only the terminal to which bidirectional devices such as cable modems, telephone modems, and bidirectional-compatible STBs are connected bidirectional. When receiving only TV broadcasts, unidirectional transmission can be switched to "unidirectional". Front operation of the changeover switch is possible without removing the terminal block. ● Transmits a band of 10-2150MHz ● The passable frequency is 70-2150MHz when the switch is set to "unidirectional", and 10-2150MHz when it is set to "bidirectional". BS and CS radio waves can also pass through. However, power supply (current passage) to the antenna or booster is not possible between any of the terminals. We recommend that you separately supply power directly to the BS/CS antenna from a booster compatible with the BS/CS band. Also, there are restrictions on use with SKY PerfecTV! Premium.
