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.


As others have pointed out, performance
will be fine. The RG-8X has a foam core
that some have found will deform when
subjected to a sharp bend, changing the
characteristic impedance of the cable.

If you anticipate sharp bends, a solid
dieletric might be preferred. For long
straight runs, the RG-8x is fine.

Yes Chuck. There is an attraction amongst hams for foil / foam coax,
probably driven by the loss figures, but without regard to the many
disadvantages that such a construction brings, or the very poor
implementations of same (not to mention any brands, lest I should be
buried).
