[Boatanchors] Feedline Spreaders

[Sandy W5TVW]

The spacing isn't very critical at all.  Anything from 2-6" spacing and wire 
from #16-#12.  Single conductor black plastic insulated wire works just 
fine.  #14 guage OK.  If you make the insulators so they are spaced about 4" 
and place a spacer every foot.  The spacers can be wood that's been soaked 
in hot beeswax for a while.  Don't try regular paraffin sealing wax as it 
will melt in the sun.  Beeswax will not.  Spacers can be made from any DARK 
plastic (plexiglas, lexan, etc.)  Avoid clear plastic as the sun will ruin 
it after a year or so.  Years ago guys were using plastic "Toni" 
haircurlers, but the sun played hob with them after a while.  Impedance? 
Anything from around 250-600 ohms OK.  I no longer use home brewed open wire 
as the "window" twin lead is too readily available (common 450 ohm stuff) 
and will handle a KW. all OK.
