In the case of that 160 meter dipole it was almost always better as a
receive antenna for 80 meters. It was better at rejecting ferocious
local QRN than the 80 meter inverted-V. Absolute signal level always
dropped owing to the mismatch, but the noise level dropped even more
improving SNR (from really deaf to pretty deaf). I am sure there were
cases where the 80 meter inverted-V was better, but that was the
exception not the rule.
Signal to noise in the direction of the desired signal is always the
issue with RX antennas, just as radiation efficiency in the desired
direction is the issue for TX.
