Telmor Twin SC-20 LNB-converter, 2 uitgangen, 10,7-12,75 GHz

The Telmor Twin SC-20 is a universal twin LNB that provides two independent outputs from a single satellite dish. This means you can connect two receivers directly, eliminating the need for an external diseqc switch in many installations. It is engineered for standard Universal LNB operation, covering both the low and high bands with a wide input frequency range from 10.7 to 12.75 GHz. With a low noise figure of just 0.1 dB, it helps maintain excellent signal quality even in challenging conditions.

Highlights

• Two independent F-type outputs for connecting 2 receivers
• Universal LNB design: input 10.7–12.75 GHz, output 950–2150 MHz
• Low noise figure 0.1 dB for clean signal
• Weather-protected housing for outdoor installation
• Simple installation with standard 40 mm feedhorn

In daily use

The Twin SC-20 is straightforward to fit to any dish with a 40 mm collar. It provides separate outputs for each tuner, so you can watch different channels in different rooms simultaneously. The unit automatically selects the correct local oscillator for the received band, supporting both 9.75 GHz and 10.6 GHz LOs. Power is supplied via the coaxial cable from the connected receiver, with vertical polarisation at 11.5–14 V and horizontal at 16–19 V.
