Is there any way to test the signal strength of the WB dish? Like with any typical satellite receiver you can usually access some menu that will show your signal strength, sometimes used to realign your dish. I have installed hundreds of sat. systems through the years and have always been able to fine tune a dish this way. When my WB system was installed the installer never once used any device; or web site, or anything/method to fine tune my dish from the recommended presets for my location. Is this common practice?
