I picked up this 7 1/2 ' mesh dish about the first of the month, and in setting it up, I am not getting a signal level. It has a Calif Amp lnbf dual polarity voltage switching C-Band, and there is a red lcd on the lnbf. I tried switching from 13 volts to 18 volts but it doesn't lite. I've checked my alignment, and it looks good. Pole is plum with level and inclinometer. I'm at Lat: 35.45, Long: 94.32, set at true south sat 95.0W pointed at about 179, apex elev at about 49, inclination set at 36, and declination reads 41. Checked f/D. and thats good. All I can figure is a bad lnbf.???
