The jump in performance by using RCA Sat Amp was very good.

Compared to what?

@abcd567

When I tried Sat Amp of another make, which had same gain~

That not quit accurate. The “claimed” gain of your RCA amp is 13-18dB (950-2150MHz)
while your first amp made no claims at all
and your third amp claimed 20dB (950-2150MHz). That’s about 5dB up on the RCA amp

Looking for ideas on why amp kills performance by > half

My first amplifier which I purchased 2 years ago, was unbranded, and frequency range 47 - 2400 MHz. When I installed it, I ended up in same problem as you. I removed it from my system. [image] My second amplifier, which I purchased 2 years ago (shortly after first one), was branded (RCA D903) and I got excellent results. [image] Nine months ago I found an amplifier on eBay, unbranded, frequency range 950-2150 MHz, and exactly like yours, for Canadian $3.66 + Free shipping from China. All…

I cannot prove it, can only say “I believe”.

You could start a religion with that, but not much good evaluating amps.
