Does anyone have some real-world experience comparing the grid with the solid 5.8 antennas. Is the listed gain accurate in describing performance? or are there additional advantages of the solid dish at equivalent gain ratings? I have only installed grid at this point, due to local high wind considerations and the cost factor. Thanks. Steve
