First let me say Hello Anyway I was able to pickup an old primestar oval dish with an LNB model NJR2162F. I noticed it had two cables going in but when I took the cover off there was only on connected, the lnb only had one connector. I read other posts about primestar dishes but none like this. Can I use it for FTA? And a second part to the question is how do I check to see if this LNB even works. Thanks
