[TowerTalk] Copper clad telephone wire

[Dave Hachadorian]

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
