I need some help me with a decision on which coax to purchase. I'm a new
General Class ham and am planning my HF setup.

The standard coax seems to be RG-8. I'm curious if I use Belden RG-8X
(9258), will there be that much difference in performance at about 100' of
coax as compared to using RG-8? I want to use the RG-8X because the smaller
diameter coax will allow me to feed the coax easier into my house. I
suppose I could try to get the RG-8 in the house, but the place where I want
to bring it in only has minimal space and the RG-8X will fit just right.

Thanks.
