Review: Lnb. Quad - Belle. Image son. Un. Peut. Haut Sur Certain. Programme Allemand
Review: Top quality and very powerful. - Got this LNB to replace a Sky one and man does it improve the signal. From channels breaking down to signal strength to 98% and Stable. I have a mesh 60 cm dish and half of it is actually covered by a bit of wall but still this LNB gave me a super result. Many thanks and I can only advice to take this and get it for yourself. I'm actually also thinking to get another one and mount two on my dish so I can get Astra 19.2 E.

### ⭐⭐⭐⭐⭐ 4 SALIDAS INDEPENDIENTES 📡
*by M***O on 14 January 2025*

📝 DESCRIPCIÓN LNB Quad para 4 participantes con filtro LTE, ideal para señal digital Full HD y 4K. Este modelo que puedes encontrar en Amazon, es la referencia para instaladores profesionales: https://amzn.to/3E6znGc 🧾 ESPECIFICACIONES • Marca: DUR-line • Modelo: +Ultra Quad LNB • Color: Negro • Participantes: 4 • Protección: Contra la intemperie • Resolución: Full HD, 4K 📦 CONTENIDO • LNB Quad DUR-line +Ultra • Manual de usuario 💶 PRECIO • 7 de Enero de 2025: 27,50€ 🟢 PROS • Fácil instalación con graduación incluida • Compatible con señales Full HD y 4K • Protección contra la intemperie 🔴 CONTRAS • Hay modelos más económicos • No funciona realmente como un quad 8️⃣ VALORACIÓN Decidí cambiar este LNB porque el anterior comenzaba a fallar, y en general, el rendimiento ha sido similar. La instalación fue sencilla gracias a la graduación que incluye, lo que facilita ajustar la orientación correctamente. En cuanto a la señal, he notado que en algunas salidas mantiene el nivel con el anterior, mientras que en otras ha bajado un poco, pasando de 72 a valores como 67 y 64, sin embargo, esto no afecta a la calidad de la imagen en general, y todo ha funcionado bien hasta ahora. Viene con protección contra la intemperie, que da tranquilidad contra las condiciones climáticas sin problemas. Si quieres alguna protección adicional, tienes esos manguitos en Amazon: https://amzn.to/4ajecg9 Este receptor es válido para señales Full HD y 4K, lo que te permite disfrutar de una calidad imagen excelente en los canales con esta tecnología. ⚠️ Lo malo de este lnb, es que en teoría funciona con cuatro salidas independientes, pero no es así, en realidad están como punteadas dos y dos. Es como si en lugar de ser un lnb Quad fuera un lnb Quattro. En la práctica, lo que sucedía con este lnb, es que los dos receptores que supuestamente estarían en la misma línea (entiendo que de la cuatro salidas estarían puenteadas dos y dos), uno de ellos comandaba el lnb y siempre tenía señal, mientras que el otro, solo funcionaba cuando el principal estaba encendido. Lo cogimos para un edificio para tres vecinos y los que estaban emparejados, uno de ellos solo veía la señal si el receptor estaba encendido. Si esta es vuestro caso, deberéis de coger el lnb de televes: https://amzn.to/3E6znGc ✅ CONCLUSIÓN El DUR-line +Ultra Quad LNB, que en realidad no funciona como un quad, sino mas bien como un quattro. Tiene una relación calidad/precio en la media de otros modelos similares. 👍 ACEPTABLE. ✳️ Espero que mi comentario ✍️ te haya podido servir de ayuda 😃
