Mount the reflector 11 ½” from the rear of the boom extension. Tighten this U-bolt securely as this
connection keeps the antenna horizontal. If your location is subject to icing, we recommend
installing a sheet metal screw to lock these two boom sections together.
2. Starting with the Reflector elements (R), slide the two halves into the element coupler until you
see the holes in the elements line up with the holes in the element coupler. Pass a U-bolt from the
hardware bag over the boom, through an element saddle and then through the holes in the
element. Align this assembly on the rear of the boom so that the U-bolt covers the mark you made
in step #1
. Install two ¼” locknuts and tighten.

3. Similarly, assemble the Director (D) and attach it at the appropriate mark on the boom, making
sure the element is perpendicular to the Reflector.

The Driven Element (DE) mounts the same way; however, the connector bracket sits between the
element and the element to boom saddle (see Figure 2).
5.
Locate the two 48” x 3/8” T-arms and the balun, and from bag #3 locate the T-arm shorting bars,
the #8 hardware and the #6 hardware. The connector bracket came with the Delrin standoffs
already installed. Using a 6-
32 X ½” screw, place an internal tooth lock washer on the screw and
