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


How about using a wood dowel? Cut a suitable length, drill holes and
apply a few coats of varnish. Might work fine, though not as creative
as the poster who suggested buttons.

These are much too obvious for me to use. Thanks.

Try farm equipment suppliers..... You should be able to get suitable
items intended to be used as electric fence insulators.

Most of those are ceramic and large but they make
excellent RF insulators.

A plastic cable tie, looped, is virtually invisible to
meet with the OP's requirements.

Jer,

No insulator is required. Either kevlar or cotton line (even when wet) have
about the same resistance as a wet or dry insulator, which is next to
nothing. Insulators or the lack thereof do not affect transmitting (1kw)
and they most certainly do not affect receiving. About the only thing the
special antenna-to-rope/line insulators do provide, is a form or strain
relief due to the wide-radius of turn around the insulator. This means when
the line holding the antenna breaks, it will probably break at your rope
knot, not at the soft-curve around the insulator. Big deal, huh. To conceal
a wire antenna, don't bother with insulators of any kind.

73,

Jack

Or use a large plastic button.

A button has the holes already drilled!
