[KYHAM] Coax Question's

[Jim Simmons]

Time to update the question; When I asked which was best, I meant best over
all. The cable will outside subject to weather, but will have no stress/load
on it. It will be completely supported. Max power will not be over 300 amps,
normally it should be much less.  I am one of those "use the least power
guys".  I do have a SB-200 that I bought and build about 25 yrs ago, I
sometimes run it into a dummy load just to check it out. If I every use it,
I will use a long wire.

After reading all the reply comments, I think that I will go with RG-8x.
What do you think?

Jim
