The Axing outdoor 4 in 1 diseqc switch is an amazing switch at an affordable price. One of the most important factors of a good disecq switch is isolation. If a switch has poor isolation, signals can interfere or overpower each other; that is why many cheap swtiches simple do not work with four signals or multiple receivers. Axing solves this problem with the highest isolation on the North American market. The return and insertion loss is also minimal so you can rest assured that you are receiving a strong signal and proper switching.
