Best cheap lnb for ku band

[arp91]

I performed several tests with 3 lnbs--sharp, dishtv monoblock lnb and Airtel lnb . Results surprised me totally as I was expecting sharp to outclass it's competitors, but exactly opposite happened.Afghansat has low signal at my location, with monoblock and aitel I get max 29-30 % signal but with sharp I get only 23-24 which just about locks the signal but picture quality is very bad.Even on other sats I got usual -5% with sharp lnb compared to the other two. So, contrary to myth of sharp being the best low price lnb, it is infact only slightly better than local lnbs that one can get for 70 odd rupees in the market.
