The suitability will depend on the frequency, length, mismatch, cost,
physical parameters, and your own threshold for loss.

The line loss calculator at http://www.vk1od.net/tl/tllc.php will allow
you to explore Belden 9258 and nearly a hundred other common transmission
lines.

Whilst RG-8/X is apparently very popular in the US, it is near
unobtainable in Australia... so availability seems to influence
"suitability". But then fewer people here purchase ready made wire
antennas like dipoles, G5RVs, etc which seem to often be packaged with
RG-8/X on US web sites.

Being in the US, I don't know what kind of coax is common in other
countries. The rg-6 is good except for two things, most of it has aluminum
for the shield that will not take solder and it has a solid center
conductor. There seems to be miles of that stuff around that can be had for
almost nothing.
The 8x is about half or less than the cost of the larger coax. Another good
reason for using it if you have several runs of it.
