I'm very sorry if I've misunderstood and/or misrepresented you. As a final
clarification (and I'll shut up on the subject after this) - if I have two
antennas with different directional characteristics, but having the same
*average* gain integrated over a sphere, in an environment of uniform noise,
what comes down the feeder is the same for both?

Yes, my headache is starting to go away. Presumably, on the low bands one
should add attenuation if necessary to get a modest but clear noise increase
in order to get best dynamic range?
