Two empty antenna elements that are attached to either end of the 4.8m ground antenna to extend it by 60cm on either side.
Do this by clipping in the hinge elements; make sure that they do not protrude the surface of the ground antenna.
The red top-plate can be lifted up so that the antenna cables can be routed through the corresponding channels, make sure the cables do not cross each other and are laying flat as they might otherwise be damaged.
Afterwards re-attach the red top-plate, some force might be required and we recommend using a rubber mallet.
Caution should be taken when using ankle or shoe mounted transponders with the 6m extension kit since there is no antenna element on the far end of each mat.
