  • All Austin Insulator bases are designed for VLF, LF, and MF use, and are conservatively rated. Choose the unit that will meet your requirements for working download, working uplift, shear and RF operating voltage.
  • If you have a requirement which we do not seem to meet or you wish us to recommend a suitable insulator, please contact us and supply us with as much relevant information as possible.
