tripelo,
Based on manufactures specs. & cost my mind tells me that my $70.00 LNA-200 should perform better than my $23.00 RCA’s but when I swap them back & forth I can’t tell any difference (signal strength & SNR). The one difference I’ve repeatedly noticed is that the RCA’s seem more immune to overload from my strong FM & TV stations when the array is pointed at them.
I’ve only found two amplifier designs that don’t show this overload issue, the RCA’s and my various PCT drop amplifiers (MA-B1015-1A, PCT-MA2-4P & PCT MA2-M). The drop amps don’t have as much gain but my SNR’s hardly change when I trade between the RCA’s & the PCT’s.
It would be really interesting to compare the dynamic ranges & strong signal handling characteristics of the various offerings.
As always, great work!
