[Elecraft] Seeking loop Antenna Parts

[Kevin Stover]

Totally agree.
I built a dipole one time and fed it with the 450 Ohm window line 
everybody likes to use.
I twisted the ends of the window line and crimped a couple of terminals 
on the ends. If it was going to be a permanent antenna I would have 
soldered it.

Two years later when I took it down I disconnected the window line from 
the 1:1 current balun and the terminals came off in my hand. Apparently 
when I twisted the strands before crimping the connectors I removed some 
of the copper. The steel wire underneath had rusted to dust a good six 
inches back. No more window line here, doesn't matter who sells it, and 
no more copper weld.
