Fracarro Satellite Receiver LNB Head
A Fracarro LNB amplifies the satellite signal collected by the dish antenna and converts it to a lower-frequency signal that can be processed by the satellite receiver. The appropriate version must be selected according to the number of outputs, polarity management, gain, current consumption and LTE protection. The UX series includes different configurations for single-receiver, multi-user and centralised distribution systems. Read more...

What is a Fracarro LNB, and how does it work on a satellite dish?
The LNB receives the signal collected by the satellite dish. After amplification and conversion to a lower frequency range, the signal can be processed by the satellite receiver. In addition to selecting the appropriate LNB, precise alignment of the antenna and the LNB is also required.
The signal-processing function of the satellite LNB
The Fracarro range includes universal, separate H/V polarity, Wideband, 6-degree monoblock and SCD2 dCSS versions. The Single, Twin, Quad and Octo models provide universal outputs, while the Quattro and Wideband versions use separate polarity outputs.
Fracarro universal LNBs in Single, Twin, Quad and Octo versions
- UX-S LTE, 287337: 1 universal output, 60 dB gain, 110 mA current consumption at 12 V, -60 dB LTE protection, approved by Sky Italia.
- UX-TW LTE, 287338: 2 universal outputs, 55 dB gain, 130 mA current consumption at 12 V, -70 dB LTE protection.
- UX-TW LTE FR, 287424: 2 universal outputs in the UX-QT LTE chassis, 60 dB gain, 150 mA current consumption at 12 V, -54 dB LTE protection.
- UX-QD LTE, 287339: 4 universal outputs, 55 dB gain, 150 mA current consumption at 12 V, -70 dB LTE protection, approved by Sky Italia.
- UX-OCTO LTE, 287340: 8 universal outputs, 55 dB gain, 200 mA current consumption at 12 V, -54 dB LTE protection.
The number of outputs determines the number of available universal connections. Twin versions with the same number of outputs may have different gain, current consumption and LTE protection values.
How many universal LNB outputs are required?
The UX-S LTE provides one universal output, the UX-TW LTE and UX-TW LTE FR provide two outputs, the UX-QD LTE provides four outputs, and the UX-OCTO LTE provides eight outputs. Selection must be based on the required number of universal outputs and the technical specifications of the individual model.
Which universal LNB matches the number of receiver points?
Single, Twin, Quad and Octo models provide 1, 2, 4 or 8 universal outputs. The output quantity must not be confused with the separate H/V polarity output structure of Quattro or Wideband models. In addition to the number of connectors, the type of distribution system must also be checked.
Quattro and Wideband LNBs with separate H/V polarity outputs
The product code of the UX-QT LTE is 287302. It has four separate H/V polarity outputs, 57 dB gain, 160 mA current consumption at 12 V and -60 dB LTE protection, and it is approved by Sky Italia. The product code of the UX-WB LTE is 287541. It provides two separate H/V polarity outputs, 55 dB gain, 100 mA current consumption at 12 V and -70 dB LTE protection.
What do separate H/V polarity outputs mean?
The UX-QT LTE has four separate H/V polarity outputs, while the UX-WB LTE has two. The local oscillator frequency of the UX-WB LTE Wideband model is 10,410 MHz. This output structure differs from that of the universal Single, Twin, Quad and Octo versions.
What is the difference between Single, Twin, Quad and Quattro LNBs?
The Single, Twin and Quad designations refer to the number of universal outputs on the UX-S LTE, UX-TW LTE, UX-TW LTE FR and UX-QD LTE models. In contrast, the UX-QT LTE Quattro has four separate H/V polarity outputs. Quad and Quattro models therefore do not have the same output structure, even though both have four outputs.
A Quattro LNB does not provide four independent universal outputs
The UX-QD LTE provides four universal outputs, while the UX-QT LTE uses four separate H/V polarity outputs. The product codes, gain, current consumption and LTE protection values of the two models are also different.
Fracarro 6-degree monoblock LNB versions
- UX-MBS6 LTE, 287139: 1 universal output, 55 dB gain, 110 mA current consumption at 12 V, -70 dB LTE protection.
- UX-MBTW6 LTE, 287140: 2 universal outputs, 55 dB gain, 190 mA current consumption at 12 V, -70 dB LTE protection.
- UX-MBQD6 LTE, 287141: 4 universal outputs, 55 dB gain, 190 mA current consumption at 12 V, -70 dB LTE protection.
The three 6-degree monoblock models have the same gain and LTE protection values but differ in output quantity and current consumption.
Gain, current consumption and LTE protection in the UX series
The gain values of the UX series range from 55 to 60 dB, while the UX-QT LTE is specified at 57 dB. Current consumption ranges from 100 to 200 mA at 12 V. The lowest specified value is 100 mA for the UX-WB LTE, while the highest is 200 mA for the UX-OCTO LTE.
The LTE protection values are -54, -60 and -70 dB. The UX-TW LTE FR and UX-OCTO LTE have a value of -54 dB. The UX-S LTE and UX-QT LTE have a value of -60 dB. The UX-TW LTE, UX-QD LTE, UX-WB LTE and all three monoblock models have a value of -70 dB.
How can the SCD2-16LNB be used in SCR and dCSS systems?
The SCD2-16LNB has one SCD2 dCSS output. It is designed to serve up to 4 SCR satellite receivers and, at the same time, a Sky-Q SCD2 dCSS decoder. Its user allocation consists of 4 SCR and 12 SCD2 dCSS users.
The LNB starts in static mode with 24 Sky and tivusat transponders. This supports dish alignment without an SCR- or dCSS-compatible measuring instrument. The installation example shows a PENTA 85 antenna, an SCD2-16LNB, a PA3 unit, two My Sky HD receivers, and Sky Q Silver and Sky Q Mini devices.
How many SCR and dCSS users can the SCD2-16LNB support?
The product code of the SCD2-16LNB is 287421, and it has 1 output. Its gain is 65 dB, the maximum SAT output level per TS is 84 dBuV, its supply voltage is 11.5-19 V, and its current consumption is 360 mA at 12 V. Its user capacity is 4 SCR and 12 SCD2 dCSS users.
Which frequency ranges are assigned to the SCD2-16LNB?
The input frequency ranges of the SCD2-16LNB are 10.7-11.7 GHz and 11.7-12.75 GHz. The SCR output frequencies are 1210, 1420, 1680 and 2040 MHz. The additional SCD2 dCSS frequencies are 985, 1050, 1115, 1275, 1340, 1485, 1550, 1615, 1745, 1810, 1875 and 1940 MHz.
Support for the EN50494 standard is specified for the listed output frequency groups. These values must be considered when configuring receivers and user frequencies.
