I have some rg-59 that I want to use for phasing a couple antennas in a
low-power environment. The 2 cables are marked as:
S.I.W TYPE RG-59/U-SP-95 MADE IN U.S.A
and
S.I.W TYPE RG-59/U-P-95 MADE IN U.S.A
I am looking for the manufacturer's data sheet to understand the
differences and characteristics of the cables. The cable marked "SP"
actually has a stranded center conductor while the other is a solid
center conductor.
The big difference, however, is the impedance of the cable. The "SP"
measures in the 63-65 ohm range with a VNWA, depending on which of
several I measure. The solid-center version measures about 71 ohms on a
single sample. The velocity factor is in the .64 to .66 range on all
cables.
Is there anyone that can point me to some data?
