Egg insulators
 
I just picked up some small egg insulators and have a question.

I had assumed that the wire went through the hole, was routed back in
the groove to the far end of the insulator, and was twisted back on
the standing part. The two loops overlap, as it were. However, the
groove for the wire continues all around the egg, including the near
end of the insulator opposite the standing part. This suggests some
kind of fancy wire routing is expected.

How come they continue the groove all around? Do these sometimes get
used with the insulator in tension and the loops not overlapping?

maybe so you can use them either direction? possibly to make the mold
symmetric which is usually easier to fabricate?

Dear Ken: The wire loops overlap. The insulator is in compression not
tension. If the insulator breaks, the wire is still, sort of, supported.
The "egg" insulators that I have used did not have a groove that went
all of the way around.
For reference: about how large are your insulators?

The loops are supposed to overlap!!! In the event of a broken insulator
the antenna is still suspended and not on the ground!!

For a successful installation use wire for the antenna [of course] and
antenna rope for the connection to the supporting end. If the insulator
breaks, your antenna is still 100% operable.

Some ceramic insulators are made both ways for simplicity.
Guy wire insulators should overlap; Antenna insulators shouldn't.

These are for QRP: Around .75" X 1.25", ceramic, green, with 1/8"
holes. Item EGS1 at:

Funny that you should mention this as I bought some at a hamfest yesterday.
This was the first time I have ever seen eggs this small. They should go
well with the K2 in the field.

After buying them, I am thinking I would just be better off with a
knot. See:

Hi there Ken ...probably under most conditions that or similar a non-typical
or traditional approach would work. Thanks for the page ...I have used a
palomar knot for years for connecting the line to a swivel as it aides in
the knot taking the direct stress and failing prematurely.
