In clear weather conditions, extremely high temperatures (up to 200 °C) can occur at the LNB feedhorn, potentially causing damage. The header cap of this Schwaiger Quad LNB withstands deformation for up to 10 minutes at temperatures exceeding 220 °C. The LNB can be used to set up a digital-compatible satellite system for up to 4 participants. The satellite receivers are connected directly to the LNB. The gold-plated F-connectors are protected by a retractable weatherproof cover.
