I need some help selecting some type of material to build some custom
center insulators. I have what approaches zero experience in this area.
The insulators will be used to support near vertical dipoles for
160-meters. The antennas will be installed in the Caribbean and will
need high resistance to UV and salt water. I also want to install an
SO-239 and home made common-mode choke on the insulator. It would be
preferable that I be able to fabricate the final shape with common
home workshop tools and not have to rely on a machine shop. The
insulators won't be under a lot of tension because of their
orientation, but low weight material would be preferred. The
insulators may be subject to some winds containing sand particles.
I'm looking for some help selecting some appropriate material (UHMW,
Ultem, UV augmented HDPE, ...) that I can investigate further.
thanks
