Then tell us all why they didn't use RG/58 at 4 GHz on C-band
satellite systems? The attenuation of RG/58 is horrible, even at VHF
frequencies.

If you want accurate data from a network analyzer the cables have to
exceed the specs of the analyzer. We used semirigid cable with soldered
on SMA connectors to test and align tubular filters in the VHF frequency
range. We used a pair of very expensive "N" to "SMA adapters on the
front panel of the various HP network analyzers to connect the test
cables to the unit being tested or aligned. We built the tubular filters
in house because the lead times were too long for custom frequencies.
