Long answer:
When working with precise time one of the very first instruments you'll want is
a frequency counter. But when your clocks get
Please forgive my ignorance but what is a TICC?

most likely the cooper is much ticker than the penetration of the lowest
frequency for which the cable is used, therefore the high frequency
"does not" see the steel inside of the cooper, that steel could cause
problem if the coax also used to carry some power -- DC or AC -- because

At least on this list if it has a solid copper core, it also has a copper
braid shield. I'm sure there is many more permutations out there.

TV co-ax these days for satellite or UHF is almost all steel wire with
copper plating. In fact the 'F' connector that is used is designed to
use that stiff wire as the center pin of the connector!

Does that effect the propagation time?

Hi
One of the easiest ways to get a slow ramp it to toss the foam box full of
cable out the back door.
Assuming it stays in the shade, you can often get a pretty good 24 hour
temperature cycle. You
still need to monitor things to know what the ramp is. Generally it’s slow
enough that you can

The recent supplement to Microwave journal has a piece on phase stability
of cables (predictably - written by a vendor of said cables..):

maybe you can recalculate your results in PPM and plot against temperature,
to compare with the
