Default source for small end insulator


I'm putting up a long wire antenna for a SW receiver. The area I live
in has severe restrictions, so I need to hide it, or at least have it
not be obvious. For the end insulators I was looking for small, about
1" long skinny plastic or ceramic insulators. I know they used to be
available, but I can't find them anywhere. Can anyone point to a
source for them? All I can find are 3" insulators with a 1" diameter.
These are much too obvious for me to use. Thanks.

Instead of using special insulators just use some monofiliment fishing line
for the ends. You could even cut up a plastic ink pen if you need an
insulator.

Skinny insulators can be made from plastic coat hangers which come in
any number of different colors. ..


Dang...I had a post printed out saying the same thing, but
I noticed you beat me to it...:/ Good thing I checked...
Those work well, but the UV will kill them after maybe...
2-3-4 years...But for the price, replacements are not a
problem. The fishing line will work also...For normal use,
I've been whacking old broom sticks, or PVC into small bits
for insulators...I drill the holes at right angles, cuz most
seem to do that... MK

I have also heard of people using buttons.

lots of good ideas so far - I liked buttons-
- add another -
black cable ties.
or
saw off a half-inch piece of half-inch PVC pipe. - the grey electrical
stuff-
or
just use a piece of black nylon fishing leader
-
hundreds more - stay tuned

I'd like to caution you against using plastic that's not intended for
outdoor use. Most types will deteriorate rapidly from the UV in
sunlight, and turn brittle and very weak in a short time. Even here in
western Oregon, most plastics become useless in a year or two, and in a
place like Denver (5000 feet high and lots of sun) you only get a few
months at most.

A better idea, in my opinion, would be to use fishing line as others
suggested, or make your own from a piece of ABS pipe or something similar.

Also, the black UV resistant tie wraps should make
pretty good insulators.

Monofilament fishing line breaks down very fast in the sun, you might
get a year out of it at best. If you’re going to attach a Dacron, Nylon,
etc line to extend your wire, why do you need an insulator anyway?
