Since our last post on the 146 Mhz Yagi Dipole test setup, parts have been acquired for the built. The elements and boom are salvaged TV antenna parts. The brackets holding it together are 3d printed. After designing the brackets,
Macarr Labs printed them out.
The reflector and director length were calculated using an online Yagi Calculator. The distance between the elements is also listed in the calculator.
Salvaged boom and elements from an old TV antenna.
The Dipole bracket is printed in 2 pieces. The smaller part keeps the elements from moving around. Threaded inserts are compressed into the printed part.
I like to mark the elements as they are built. This makes final assembly easier.
The elements on the Dipole mount are are temporary and will be changed out during Dipole testing.
The mast in the picture is a stick of pvc conduit. This is temporary until a fiberglass mast is acquired.
