Technically, most SWR pickups are made from MICROstriplines because they usually have only one ground plane.

Provided the pickups microstriplines are 1 mm or bigger they will handle Kilowatts. There is no problem with laying an extra piece of copper wire along the central microstripline to allow more current.
