Best Plastics, Composites, Rubber for structural antenna parts

Just a warning note about using ABS for structural parts that I've mentioned many times before - hopefully what you're planning to use is the thick walled stuff that has little or no flex. If you go to Rona or Lowe's or Home Depot and shake a 10 foot ABS pipe like a sword it flexes a lot. ;) It seems to be rigid, but its not. If you shake a length of PVC like that it will seem like a wet noodle, so avoid using PVC for structural use either, except when recommended in build plans.

From experience I'm clarifying that ABS should never be used as a pole or mast, and it should be carefully considered if you're thinking of using it as a horizontal boom of any length more than a meter or a few feet.

Mail order source for "unobtainium" G-H rod spacers

It seems worthwhile to repeat this information here.

There is a USA mail-order source for unobtainium spacer material, similar to what I use in my own antenna builds. They can ship by post, worldwide.

See the original thread for details.

This material is rigid fibreglass tubing, 1/4" inside diameter and 1/2" outside diameter. Perfect for spacing solid aluminium reflector rods in a G-H antenna build. Other diameters are also available.
