You caught that just as I was posting the correction.

Actually, I meant the converse...

Yes, but I make a case to install Rx Pre-amplifiers in
some locations where others might say they are not
effectively contributing all the time. As long as the
pre-amplifier isn't over-loaded and causing grief, I
like to have them in operation. The advantage of the
installed preamplifier is fairly obvious in relative
system comparisons.
And just to throw another log on the fire (keeping the
subject nice and warm)... I often use pre-amplifiers
with T/R (coax path) Relay bypass capacity. For more
than one reason I can and do remotely toggle pre-amps
in and out of operation.
