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

If you want it, you can have this antenna FOR FREE. I have programmed all my radios to VHF only, so no need for UHF antennas any more.
