Yea my first was ChannelMaster manual tune with an LNA.
My neighbor came over when I had some problems with reception
(he then told me he sold and setup systems in the midwest) and he
introduced me to a new thing called a Low Noise Block.Boy, like all
other technological boons things have changed...
I still have the ChannelMaster dish but retired it a month ago due to the 1"
diameter pivot pin rusting in half.
