Note: If you are installing the antenna assembly on a metal pole
mount, it may be easier to attach the feed arm after you have
installed the antenna on the Az/El cap. See Installing the antenna
assembly onto the mast on page 28. However, if you are using a
ladder, it may be easier to attach the feed arm to the antenna before
installing it on the Az/El cap.
Note: Make sure the feed arm is oriented as shown in Figure 24.
