These four elements enhance NVIS and attach at the top on your match (Z0) and at the base of the vertical element (Z1) per the image below.
These same 4 NVIS elements are then run to (Y1, Y2, X1, X2) and secured with the included spikes into the ground through the included insulators. They should also be evenly spaced once deployed, and should not lay on the ground, but be pulled out like guy wires would be.
An 8’ grounded counterpoise wire (Z2) should attach at the bottom of the match (Z0) and its ground spike be run into a physical dirt ground. That grounded counterpoise, should not be placed directly under the NVIS Elements, but it should instead be run between any pair of the NVIS elements.
