Amplifier received. Without delays and damage. Works bad! Compared with the previous purchase of the same amplifier, The gain is worse at 10dB. Not 26DB (145MHz) as before, but only 16db. At 435MHz - NF = 2.21. The former instance had NF = 0.4db. And so on all over the range, up to 3GHz. Compare the graphics with the previous same amplifier. I was very unhappy!
