The Invacom QDH-031 is a high-performance Universal Quad LNB featuring an integrated feedhorn and four independent outputs. It is particularly suitable for satellite installations where reception conditions are challenging and a stable signal is essential.
Its four outputs allow up to four satellite receivers or tuners to be connected directly to the same satellite dish. Each connected receiver or tuner can independently control the required polarisation and frequency band.
With a typical noise figure of 0.3 dB and a gain of 50–60 dB, the QDH-031 provides strong reception performance. Its integrated feedhorn is designed for satellite dishes with an ideal F/D ratio of 0.6.
The LNB has a standard 40 mm mounting neck and can therefore be installed in many conventional LNB holders.

🔧 Use and Connection
The Invacom QDH-031 is installed in the satellite dish’s 40 mm LNB holder. The LNB should be rotated and carefully adjusted to achieve the best possible signal strength and signal quality.
Each satellite receiver or tuner must be connected to a separate LNB output using its own coaxial cable. A receiver equipped with two tuners normally requires two separate coaxial cables and therefore uses two of the LNB’s four outputs.
To allow all connected receivers to operate independently, the outputs must not be combined or divided using a conventional antenna splitter.
