[Antennas] Open Wire Feedline

[Ken]

Randy;
    Thanks, I already have the pens, So I'll try them.  I didn't even 
think about the insulators from Tractor Supply, even though I have a few 
on my fence.   The pens and #18 wire  should get me around 600 ohms.  I 
have to get it made, mount my Zebco 303 on my slingshot and shoot it up 
into one of my cottonwood trees.  I'll let you know how it works out.

Ken
