You would like to know ways by which the low noise block can be modified to enhance satellite signal conditioning in a receiving station?

Stay out of the LNB ! It's already optimized at the factory before it's shipped

to the dealer. Can you think of any reason why a device capable of more

performance would be adjusted for lessperformance by the manufacturer ?

I can't either.

The steps available to you to enhance satellite reception are ...

-- use a larger reflector (dish)

-- make sure the dish is accurately pointed toward the satellite

-- keep snow, ice, rain, leaves, tennis balls, and bird droppings out of the dish

-- make sure the polarization of the feed assembly is properly set

-- make sure that the aperture of the feed is located precisely at the focus of the dish. Items #2, #4, and #5 were the responsibility of the installer when he delivered

your system. Those guys work under incredible time pressure, with a quota of

installations to complete each day no matter what conditions they find, and

they're shamefully underpaid. It's not unthinkable that the installer might have

called it before the pointing, polarization, and focal adjustment were

totally optimized to the last tenth of a dB. Those fruits hang much lower than

the likelyhood of digging into the LNB and improving it. (Plus, when you give up,

you'll never get the weather gasket properly reseated, and it'll start taking in rain.)
