[TowerTalk] Aluminum Fence wire for elevated radials

It should work well for temporary or permanent antennas.  I've seen them on TV (OLN and OTCH) used to keep deer out.  Looks like good stuff.  Should broadband the antenna a bit, like using ladder line or like a cage dipole.

  Been a while since I bought electric fence wire, but the last 'wire' I 
  bought was stainless.  The last electric
  fenceing material I bought was nylon with wire inbeded.  Worked great 
  and was a lot easier to put up.
  Anyone have any thoughts about using this 'stuff'' for field day type 
  antennas?
