I bought it from SOLID's website.
Yes, I did find signal increase and signal stability.
From a fluctuating signal of 90/56-63, it went to a stable 90/71 stable signal, on 68e c-band, after using the scalar.
I havent used ku feed horn, this scalar doesnt fit onto ku lnb, only fits c-band lnb.
Though I got 2-3 % signal sitability on ku lnb as well. But for Ku lnb, there are different scalars.
