>  Yes, BUT --  coax loss on RX only matters if the limitation is noise in 
receiver.  That is VERY RARE on the HF bands, where the major limitation is 
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, just as good  on receive as your 
multi-element yagi if it was all fed with the same  coax? Isn't gain gain and
