This has great information.  There is a practical issue.  I have
RP-TNCs and Ns for RG-58.  If I were to, say, go to RG-6, I'd probably
need a new die and new connectors.  The cost is $100 for the
connectors at a minimum (min order from pasternak unless others have
recommendations for RP connectors).  If I am going to spend $100, I
might as well get good cable.  The problem is getting an RP-TNC to
match the cable spec.  I've got the following choices: RG8, RG9,
RG213, RG214, RG225 & RG393.  There are some others, but they appear
to be thinner, e.g. RG55, RG141, RG142, RG223 & RG400.

The coaxloss.htm lists RG-213, which I assume is what I should go for
(~8db at 1Ghz).  I assume crimp is better than clamp(?).  And that
RG6, RG11, or the Belkin RF99xx cables don't match any of the
above(?).

Make sense?
