Hi Patrick. That's a nice looking log periodic.
Since this is mainly a left-pondian forum the subject of aerial connectors may need a bit of explaining. Most of the world including the USA has used F connectors for aerials for many years. It's really only the UK that has kept the traditional Belling-Lee co-ax connector. To a lesser extent it's used in the rest of Europe.

The F connector is a much better connector. Better screening, better return loss. Easier to wire too. Though you do need the correct size conenctor for the cable and the simple versions only work with solid core co-ax.
