70 CM YAGI from scrap project

I started a new UHF project. I first started making a 2m “7db for 7 $“antenna, and that is almost done. While the silicone is hardening on the VHF antenna, I started on to the UHF version. I made a Excel spreadsheet Yagi calculator and the dimensions are based both on this spreadsheet and the “7db for 7 $” formulas.

Materials (so far):

  • Reflector and driven element scavenged from scrapped tv antenna
  • Boom and directors from scrapped blinds. Driven element halves are also kept together using a rod from the scrapped blinds.
  • Acrylic/silicone and Loctite epoxy
