The beam has a pattern and it increases the signal strength in the direction
that it is pointing and lessens it in the direction that it is not pointing.
The vertical receives signals in all directions. So I would take a 10dB
gain beam with 10dB cable loss over a vertical any day for RX on HF.

I'm not splitting hairs about noise limitations of your rx.
Are you saying that the practical effect of a gain (less loss) of 3 dB
on the air due to lower loss coax is not heard on your receiver? So your
dipole, vertical, coat hanger, etc.is just as good on receive as your
multi-element yagi if it was all fed with the same coax? Isn't gain gain
