either QRM or noise picked up on the antenna. In other words, on HF, coax
loss only affects TX.
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 and
loss
loss?
