10.  Perform 

coarse elevation

 adjustment by loosening the large knob on the elevation 

adjustment assembly and sliding the inner and outer cylinders with respect to one another to 
lengthen or shorten the elevation arm.   Lock the assembly by tightening the knob.   Attach the 
magnetic inclinometer to the lower box-beam segment of the antenna support arm as shown in 
Figure 11.  Fine adjustments   to elevation will be made by rotating the entire elevation adjustment 
assembly clockwise or counter clockwise as required to fine tune the reflector dish in elevation in 
step 17 after the radio has been installed.

11.  Install the 

upper dish

 segment.   Place the upper dish segment on top of the lower,  

engaging the latch pins and alignment bolts/pins to ensure a smooth-appearing parabolic fit.   
When the two segments are aligned, and form a smooth parabolic surface, engage the latches 
and/or pins.

12.   Dismount the 

radio arm

 from its transit position, on the back of the antenna support 

arm.   The radio arm is held in its transit location with a single wing nut and washer.  Replace the 
washer and wing nut for later use.   Install the radio arm by inserting the open slotted lower end of 
the arm (Figure 5) over the bolt in the end of the antenna support arm.   Slide the radio arm over this 
receiving bolt at a shallow angle.   The radio arm simply slides over this bolt.   Note how the hole in 
the radio arm will then align with the lower dish dowel stud at the base of the antenna as the radio 
arm is raised into place.

13.   Remove the 

side arms

 from their transit storage location on the back of the antenna.   

These two arms are simply held in place by friction and have no transit retention hardware.   Install 
the radio side arms by slightly loosening the wing nuts on each side of the lower dish segment.   
Similarly, the radio arm has two wing nuts which will accept the other end of the radio arms.  Lift up 
the end of the radio arm, which will cause the lower dowel stud in the dish to engage the alignment 
hole in the radio arm.   Complete the side arm installation by dropping each arm over its respective 
wing nut studs.   Finger tighten the wing nuts.

14.  Install the 

radio

 (with horn and bracket) by removing the two wing nuts and flat 

washers on the radio arm.  Lower the radio and bracket over the two captive hex bolts.  Secure 
with washers and wing nuts.  Check the polarization of the radio.  Connect the radio to its 
power supply and receiving/transmitting electronics.
