This is my first post to the forum so forgive me if i screw something up. My question is about the compatibility of an LNB and a receiver. I was given a receiver to use with Direct TV and I already have a Direct TV dish on my house. The receiver is a D11-500 and the dish LNB is a Cal-Amp 150517. I am very new to satellite set ups but believe everything is hooked up correctly. After aiming the dish I can't seem to get a signal reading on the box signal meeter. Thanks in advance for your help.
