Well today I made the gamma section for my Yagi and mounted it and also added rubber bits for the ends of the elements and end caps for the boom. I have done a quick test of the Yagi with a 10pF capacitor and the SWR is ~1.5-1. I got a couple air variable capacitors I going to put on the Yagi to better tune it. As it was a lovely day most my work was done outside on the deck.

Tonight this is the bracket I made for the SO238 socket all riveted and mounted to the boom of the Yagi. All that is left to do is make the bracket to hold the gamma matching and to fine tune the Yagi, all going well I should have it finished during the week
and yes working on the kitchen table again, hehe
