Secure the parasitic elements to the boom:

• Hold the boom in a small vise as shown.

• Insert and center an element into the boom, beginning with the reflector. Use a small hammer and tap it through gently.

• Using a center punch, stake the boom next to the element in two places, preferably opposite one another. Stake at a 45 degree angle toward the element as shown on the right, and at the 10:30 and 4:30 positions as shown in the inset below.

• Stake the element on the other side of the boom as well.

• Attach the rest of the elements in like manner.
