I have asked jenius-jatt. The bird term is used generally in sat tracking field to mention satellite as you are new sat tracker, you don't know about it. I understand that.
Yes it show's good signal strength, but as you know the product is of very cheap price and according to that its very nice. But more accuracy will be on Digital sat finder and it is costly too.
This Analogue sat finder also show's Vertical or Horizontal freq. when catch the related LED start blinking of that particular polarization. You can see in above image the 22K is their ,One compass is their for N.E.W.S direction. On the whole good for Normal use.
