Topband: Using CAT5 in place of coax (was video baluns)

[Rick Karlquist]

I did some careful measurements of CAT5 cable a few years ago
using a 4 port network analyzer (NOT a 2 port VNA with baluns).
On my random sample, the characteristic impedance was within
5% of 100 ohms.  The cable is fairly lossy, which is no
surprise given the tiny wires.  There doesn't seem to be
any compelling reason to use it in place of RG-6.
