For One and All,

My Thoughts on a Slinky Stretched-Out on an Eight Foot Long
PVC Pipe
http://groups.yahoo.com/group/Shortw...a/message/6096

Think of (Imagine) an Eight Foot (8') piece of One Inch (1")
Copper Pipe as an Antenna Element.
= = = Looks like a 'Fat' Wire to RF.

Then think of (Imagine) an Eight Foot (8') piece of 3/4" PVC
Pipe with a Single Copper Wire stretched-out along it as an
Antenna Element.
= = = Looks like a 'Skinny' Wire to RF.

Now a Slinky is Coiled 72 Feet Piece of Wire.

Divide 72 by 8 and you have the Number "9".

Next think of (Imagine) the same Eight Foot (8') piece of
PVC Pipe with a Nine evenly space Copper Wires stretched
along it as Antenna Elements.
= = = Looks like a low resistance 'Fat' Wire to RF.

It is 'My Opinion' that a Slinky that is also stretched-out
along an Eight Foot (8') piece of PVC Pipe with the Coils
evenly spaced (72 Feet of Wire) along it as an Antenna Element.
= = = Looks like a high resistance 'Fat' Wire to RF.

The slinky is going to be a stretched out coil and not behave the same
as a copper pipe.

Larger diameter antenna elements are more broad-banded. You can
electrically create a larger diameter element with parallel wires
separated with spacers.
