Topband: Base Insulators for Verticals

[Robert Seymour]

Needed - Base insulator Information for upgrading my low ban vertical.  I checked the archives and found references to Antenna Mart but the owner passed away so that source is no longer available.

Please advise of other sources or has anyone made their own with "plastic" rods such as G-10 epoxy laminate?

Since I live very close to salt water I need to be mindfull of corrosion with dissimilar metals.

Thanks Bob AF4OX
