Why?

If you use insulating rope there is no need to buy insulators.


Well, that could be debatable. Do you have any way to quantify the RF
leakage of wet rope vs. a wet insulator to support your contention?

Rainwater doesn't conduct very well.


Well, THAT'S debatable too. Sadly, in today's world, rainwater can
contain a lot of sulfuric acid (pollution from coal-fired power plants),
and H2SO4 is a -very- good conductor.

Sorry, a) I am old fashioned and b) I am also used to transmitting on my
antennas.

If you were just receiving and desperate to save a couple of bucks on
insulators, you -may- be able to get away with it (or not).


Joe from Kokomo,

There are All Sorts and Forms of Pollution in the Air :
Chemical + Particle + Mineral + Organic
-and-some-of-them-when-mixed-'conduct'-
An Antenna Support/Rigging Rope that has been
In-the-Air for a Year is a "Dirty'* Rope.
* Contaminated

The Soft Woven Rope can Absorb the Rain Water
-and- Now you have Water 'mixed' with what all the
Contaminates that have penetrated the Rope.
-result- The Rope is no longer as good an Insulator
as when it was New un-contaminated and dry.
-while-
The Hard Insulator has the Surface 'contamination'
Washed-Off.
-result- A Good 'Clean' Fully Functioning Insulator )

well that is how 'i' see it . . .
