[QUOTE="ralphmagno, post: 647470, member: 189146"] hello the lnb can be adjusted no problem. but what frequency will you be reciving? the osc can be adjusted by about 90 mhz. if they were transmitting on a frequency of 10660 ghz your receiver will not tune below 10.750 so moving the lo to 09.660 ghz and bingo the receiver will receive a frequency transmitted below the satellite band by 90 mhz. the receiver will say 10.750 even though you are receiving a signal at 10.660. they are probaly using hor or vert polerazion. this is like a mmds system and without the ofset on the lo no one will pick this up. a 1 watt transmitter will at 10.6 ghz will go 20 km line of site with a 30 cm dish and 30 km witha 60 cm dish. if you know the frequency it would be easier. i have modified 100 lnbs like this. the f-wave is the easiest ralph:) [/QUOTE]
