Cooper Wire inside Balanced Line

Unused freshly stripped 450 ohm balanced line compared

to weathered 300 ohm balanced line freshly 

stripped back to expose the copper wire.

These are the ends of a 6" section of weathered 300 ohm 
balanced line. The bottom image was 
unexposed (freshly stripped).

Dipole 220' May 1, 2020

It is May 1, 2020.  I put the antenna analyzer on the the 220' dipole and the Full Wave 80m Loop today.  The following plots show the SWR characteristics of the dipole.  The next post reports on the full wave loop.
