I've been apprehensive about building my own yagi antennas before. It seemed so complicated. But then I started tinkering with antenna modelling software and decided it couldn't be that difficult. So I started building.
Life was so much easier when I realised that with a gamma match I did not have to split or isolate the elements from the boom.
On the pic is my 6m5el and my 2m5el yagis. 6m is a lot of fun this summer. There's a 10m/20m moxon spider beam coming up next.
I've been thinking of making a 6m moxon, so I'll be interested to see your design. Those Yagis look great though!
