Maybe when you cut it, the copper mashed down so you couldn't see
the steel core. Try scraping off the copper with a knife.
Measure the diameter before and after with a micrometer or even a
machinist's ruler.

Subject: [TowerTalk] Copper clad telephone wire
I have lots of old copper clad telephone wire that I want to use
for radials
and antenna wire. This is the stuff that is bare and went from
pole to pole
for old telephone lines. It is not the insulated drop wire.
When you cut it, it looks like copper all the way thru but it
will attract a
magnet.
I want to use this stuff on the low bands (160, 80, and 40).
Is there a way to measure/determine how thick the copper layer
is?
Measure the resistance, wind a small coil and measure Q?
Thanks,
Gary K4FMX
