[QUOTE="Tururu, post: 932908, member: 227656"] It is to play with the reflected signal at the antenna, an antenna of 80cm each 6º to put a displaced LNB, estimated to be as losing 5cm diameter antenna. So will your performance gain in dB. ------------ Es jugar con la señal reflejada en la antena, en una antena de 80cm cada 6º al poner un LNB desplazado, calcula que es como perder 5cm de diametro de antena. Asi sera su rendimiento, ganancia en dB. An example Astra and Hot Bird satellites are in the same position, but the antenna is focused on one or another satellite. ------------ Un ejemplo con Astra y Hot Bird, los satelites estan en la misma posicion, pero la antena esta centrada a uno o a otro satelite.
