A
selection of photos of equipment and antennae built rather than just bought…
The folded dipole
assembly for my most recently built portable 432MHz Yagi.
And a view of
432MHz folded dipole, from the other side…
One of the four new 14-element Yagi for 144MHz, having the dipole assembly fitted.
Views of the original folded
dipole-mounting block – Teflon and aluminium, with stainless steel
fasteners. These photos remain here to
remind me what not to do next time! The
large slab of aluminium angle creates unwanted capacitance across the
feed-point. All the mounts have now been
modified by cutting along the line shown, thus removing about 80% of the plate.

balanced lines used in the 4x arrays; RHS: Drilling the 6.5m long booms for the
432MHz Yagi.

28-element Yagi.
