The GT-SAT GT-WB1 is a Wideband LNB designed for modern satellite installations using a compatible Wideband multiswitch or dCSS/Unicable system. Unlike a conventional Quattro LNB, which requires four outputs per satellite position, this LNB delivers the complete satellite band through only two outputs: one for vertical and one for horizontal polarisation.
Wideband technology converts the low and high bands of each polarisation into a continuous output range of 290–2340 MHz. A compatible Wideband multiswitch therefore requires only two signal inputs per satellite position instead of four.
The GT-WB1 has a 10.41 GHz local oscillator, a specified typical noise figure of only 0.1 dB and a gain of 56–62 dB. Its standard mounting arrangement and 42 mm feed-neck length make it suitable for many conventional satellite dishes.
This is an installation LNB for Wideband systems and should normally not be connected directly to a conventional satellite receiver. The signal must be processed by a compatible Wideband multiswitch, dCSS unit or other equipment designed for Wideband LNBs.

🔧 Connection and Operation
The GT-WB1 has two F-outputs:
Both outputs are connected by separate coaxial cables to the corresponding Wideband inputs on a compatible multiswitch. The multiswitch then processes and distributes the signals to receivers or Unicable tuners.
A conventional Quattro LNB requires four cables per satellite position: vertical low, horizontal low, vertical high and horizontal high. The GT-WB1 requires only two cables because the complete frequency range for each polarisation is available through one output.
This LNB must not be confused with a Twin LNB. Although the product has two F-connectors, they are not two independent Universal LNB outputs for directly connecting two receivers.
📡 Comparison with a Conventional Quattro LNB
| Function | GT-WB1 Wideband | Conventional Quattro LNB |
|---|
| Cables per satellite position | 2 | 4 |
| Vertical polarisation | Complete band through one output | Split into low and high bands |
| Horizontal polarisation | Complete band through one output | Split into low and high bands |
| LO frequency | 10.41 GHz | Usually 9.75/10.60 GHz |
| Direct connection to receiver | No | No |
| Compatible multiswitch required | Yes, Wideband | Yes, Quattro |
