TELE System TS401F Quad Universal LNB – 0.7 dB Noise Figure, 4 Outputs & LTE Protection

The TELE System TS401F is a quad-output universal LNB designed for multi-receiver satellite installations. It connects to a single satellite dish and provides four independent outputs, each capable of feeding a separate receiver or set-top box. The 0.7 dB noise figure ensures clean HD signal reception on all four outputs simultaneously, and the LTE protection feature blocks interference from 4G/LTE mobile networks.

The TS401F covers both the low (10.7–11.7 GHz) and high (11.7–12.75 GHz) satellite frequency bands. Each output delivers a frequency range of 950–1950 MHz (low band) or 1100–2150 MHz (high band), controlled via the standard 13/18 V polarisation voltage and 22 KHz tone from the receiver. The weatherproof housing handles operating temperatures from -40°C to +60°C.
