EchoStar 119 is Ku, just Circular, a Linear LNB can "pick up" Circular signals, just at such a reduced strength you can't get video / audio.
Think of the Meter as a Hearing Aide, it makes things "louder", it does not process the signal.
The Receiver, like a Stereo, needs to be listening to a specific Freq. (transponder) to process the signal. On a Stereo, you enter / tune to a specific Freq. and if a sataion is broadcasting on that same Freq. you will hear someting, otherwise you hear static.
Same with satellites, you need to be aligned exactly at a Sat and have one of it's Active Transponders pre-progammed and selected, the "Quality" indicator will Light Up, scan and you will get a picture.
Keep at it, you are almost there, just letting logic get in the way. This stuff doesn't always make sense, but it works.
