Wideband Technology<\/h1><\/div>

Thanks to the wideband technology, the LNBs can be connected to the Fracarro SCD2 multiswitches with only 2 coaxial cables for each satellite, allowing quick and easy installation even in the smallest spaces.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

With\u00a0WIDEBAND technology<\/strong>, the LNB provides the\u00a0entire horizontal and vertical polarity<\/strong>\u00a0on the two outputs, occupying the band from 290 to 2340MHz and leaving to the multiswitch the task to divide each of them into the two low and high portions.<\/p>\n

As in\u00a0QUATTRO technology<\/strong>, the multiswitch then sends to the receiver only the required band (VL, HL, VH or HH) or the single transponder depending on the DiSEqC command received.<\/p>\n<\/div>

Wideband and QUATTRO: comparing technologies<\/h2><\/div>
<\/div><\/div><\/div>

Cables number<\/h3><\/div>

With WIDEBAND technology,\u00a0the number of coaxial cables<\/strong>\u00a0connecting the LNB to the multiswitch\u00a0is half (2 instead of 4)<\/strong>: installation is therefore faster and easier, even in the case of\u00a0limited space<\/strong>. Using existing cables, the WIDEBAND technology also makes it possible to convert a traditional QUATTRO single satellite system to a WIDEBAND double satellite system: in fact, both Hotbird 13\u00b0E and Astra 19.2\u00b0E can be received and distributed with only 4 cables coming down from the roof.<\/p>\n<\/div>

Products selection<\/h3><\/div>

The bands occupied by the LNB output signals that go towards the multiswitches are different in the two technologies and may also vary on different LNB WIDEBAND models; for this reason, if you use a WIDEBAND type LNB with a local oscillator at 10,410 MHz (the most common on the market), the\u00a0multiswitch connected<\/strong>\u00a0to it must also be\u00a0WIDEBAND compatible<\/strong>\u00a0and calibrated on the same frequency as the oscillator.<\/p>\n<\/div>

Decoder and distribution<\/h3><\/div>

They are the same in the two technologies because the satellite signal at the output of the QUATTRO or WIDEBAND multiswitch, which serves the user socket, always occupies the band from 950 to 2150MHz;\u00a0cables, splitters and receivers<\/strong>\u00a0(be they legacy, SCR or SCD2 dCSS) are in any case\u00a0compatible with both technologies<\/strong>. In WIDEBAND systems, when there is a signal division along the down conductor (between LNB and multiswitch) it is necessary to use products with\u00a0band up to 2340MHz<\/strong>.<\/p>\n<\/div>
