nd
Option: Bird Bath Method, installing by sections with BACK BRACES .
(Using 2-3 People)
*IMPORTANT: If you purchased an antenna without back braces continue to page 8.
Assemble mount and put mount in birdbath position (See picture C below).
Step 1: Install the brace clips to the back braces before placing on the antenna lip and ring. Have all 4 brace
clips installed on the brace before going to the next step. See brace clip and back brace photos below.
Step 2: Install brace clips to the ends of the 4 back braces and install the ½” nut on the threaded rod end of the
back brace, threading it down approximately 4 to 4 ½” down the threaded rod (see FIG. #13).
Step 3: Take the first panel and install it to the ring of the mount finger tight. Be sure to find the pilot hole on
the mount and on the antenna. Take the back brace that is ready and put the threaded rod through the tab on the
ring (see photo A). Take the other end of the rod with the clip and attach the brace and clip to the lip of the
antenna section (see picture B).
Step 4: Insert ½” x 3” bolt (see FIG. #17 for washers and rubber placement) from the antenna to the mount.
Have one person continue holding the panel in place while the second person attaches the back brace.
(Remember the threaded end of the back brace should already have the ½” nut on the threaded end about 4-4 ½”
on the threaded rod and the bent tab already installed on the ring, see FIG. #15). Insert the threaded rod of the
back brace into the bent tab and bolt brace clip on the edge of the antenna with 3/8” x 1 ½” bolt, 3/8” nut and
3/8” lock washer. Make sure everything is finger tight.
Step 5: Pick up the second antenna panel and be sure the numbers line up and bolt in place just like the first
panel. (see FIG. #9) Once secure you can begin bolting the two units together by placing the ¼” x ¾” bolts
through the templates. Again only finger tight. Continue for the next 2 panels. To allow for greater ease in
aligning the templates we recommend that you use an alignment punch tool. (see FIG. #10).
STEP 6: You will notice all 8 bolts in the face of the antenna have been installed from the antenna to the ring at
this point. You now remove every other bolt from the face of the antenna and replace them with a feed strut.
