[Antennas] Need a bit of wire advice

[IamSF5@aol.com]

Hi Gang,
I have a lot of 14 GA unsulated wire for an antenna that is ready to go up.
But after looking at the 15-M antenna that has only been out in the weather 
for a summer it sure loks cruddy.
I get this bare strand wire for free but how will all the built up crud 
affect it?
RS has # 14 insulated wire in a 100 foot spool at $21.95 and on the spool it 
says indoor/outdoor.
The color is brown and not as easy to spot.
So use the bare wire or insulated?
Thanks
Bob
