Pete Higgins gave a report of his LNA200 tests on another forum. He wasn't any more impressed with its performance than ADTech was: it's an OK preamp, but not as good as Winegard says it is.
I am presently using a LNA 200, but plan to do some testing. I want to get a Kitz Tech pre-amp and see if it will add to my signal strength, what I read it would be helpful addition to my set up I am working on right now.
The Kitztech KT-200 has a low noise figure that might improve the reception of weak signals, but it is not likely to make your signals stronger. If you buy it, get the KT-200 with the outdoor enclosure.

Also, has anybody else to used this Winegard LNA 200 ?
I am planning to make some tests, if I have the time. My concern is about the voltage to the preamp since it uses a 5V power supply. A long coax run might cause the voltage to drop too low for proper operation.

I tested the CM7777HD for voltage drop. It can go as low as 4V measured at the preamp. I don't like the enclosure for the 7777HD; it doesn't seem like a good design for outdoor use. I use it indoors as an instrumentation amp for testing.
If you can not measure it, you can not improve it.
