If you are looking for a new project perhaps check out g0ksc.co.uk where you will find lots of yagi designs. More oriented to VHF/UHF you will also find some HF designs if that’s your thing.

The operator of the site is Justin G0KSC who also has an antenna manufacturing business named Innovantenna. Thankfully he puts his designs up on the G0KSC site so anyone can access them for free. It’s worth a look for inspiration.
