There are lnb's with low db 0.3, but that dosen't mean anything because some compoanies inflate the numbers just to sell.
I watch a weekly program called "Télé Satellite" on the internet. it's in French and they have a lot questions from their viewers about what the best lnb in the market and they always say that anthing less than 0.5 db is not possible and somtimes even a 0.7 db lnb can be better tahn a 0.5db depending in teh quality and circuits. They also say that teh temperature, humidity, clouds can affect the lnb performance.
If you curiose and you want to say a video from their weekly episods go to :
