Opticum ANT0188 Satellite Dish 83 cm White – Steel Offset Dish, Ø20-50 mm Mast, 38 dB Gain

The Opticum ANT0188 is an 830 × 750 mm offset satellite dish in white, built around a galvanised-steel back support with an aluminium LNB arm and plastic LNB holder. It's the workhorse dish size for reliable reception of Ku-band satellites across Europe — big enough for a strong margin in poor weather, compact enough for a balcony or gable wall.

The steel reflector delivers 38.1 dB of gain at 11.75 GHz with a tight sub-2.2° half-power beamwidth and over 27 dB cross-polar discrimination, so it separates satellites cleanly. The mast clamp fits Ø20-50 mm poles, elevation adjusts across 10-90°, and the dish is engineered to stay put — rated to survive wind loads well beyond normal storm conditions. Pre-assembly makes install straightforward.
