gabshere: I removed the lnbf today, taking note of the fd scale. Taking the back off of the lnbf, I soon recconized my problem. It had taken a good hit at sometime past, one of the small components which is probably a resistor or diode blew completly off the PCB and about halfway melted another. So, I'll be getting a new lnbf. The cable is good, as I'm just setting this dish up. Picked it up on January 2nd, 7 1/2 foot Odoom. I live way to far from you, I'm at Van Buren, near Fort Smith, but I thank you for your offer. Sadoun has a GeoSat Pro, but it's C-Ku, and I only plan on using C-band. If I use the BSC 421, could I use foil tape around the barrel to shim it up?
