1. Press and hold “POWER” for two seconds to turn on the 

interface box. Wait until the interface box finishes “connecting 
to antenna.” The antenna may enter the search routine after ten 
seconds. Pay attention to the pinch points as the antenna raises!

2. Wait until the antenna has at least raised to a position 

in which the LNB arm is parallel to the roof. Then, press 
“POWER” and “SELECT” at the same time. The antenna 
should stop moving.

3. Unplug the interface box. 

4. Remove the four reflector nuts and bolts with a ½

 wrench, 

and remove the reflector. Discard the reflector, nuts, and bolts.

5. Remove and set aside the 

four nuts and bolts holding 
the LNB guard to the feed 
arm. Then, slide the LNB 
guard down the feed arm 
and toward the reflector. 

6. Remove and set aside the 

two screws holding the 
LNB to the feed arm.

7. Carefully slide the LNB out from the feed arm. 

Disconnect the coax cable from the LNB using a 

7

/

16

 wrench, and set aside the LNB.

8. Once the LNB has been 

removed, remove the LNB 
guard from the feed arm.

9. If there is not already a line marking the top of the stiffener 

plate, draw a line to mark the top of the stiffener plate. 

10. Using a ½

 wrench, loosen and remove the four bolts 

holding the reflector bracket and stiffener plate to the skew 
housing. At the same time, carefully remove the stiffener 
plate and LNB arm assembly. Set aside the stiffener plate 
and four bolts; you will need these later.

11. Identify the fourth outer hole 

in the adapter plate. See 
numbered holes to right. The 
fourth hole marks the bottom 
of the adapter plate.

Note: as the antenna raises and turns, the adapter plate may become 
skewed, and the fourth hole may not be directly at the bottom of the plate. 
If unsure of the fourth hole, remove the four screws from the center of the 
adapter plate; a small post is located directly above the fourth hole.

12. Position the reflector bracket against the adapter plate. Make 

sure the fourth outer hole in the adapter plate is centered in the 
bottom slot of the reflector bracket. The third and fifth outer 
holes should be close to opposite edges of the bottom slot.

13. Place the stiffener plate inside the reflector bracket. Make 

sure the second and third outer holes in the stiffener plate 
are centered in the bottom slot of the reflector bracket (see 
above). The second and third outer holes in the stiffener plate 
should additionally align with the third and fifth outer holes in 
the adapter plate.

14. Install bolts through the four outer holes in the stiffener plate, 

and tighten.

15. Slide the LNB guard onto the feed arm.

16. Run the sheathed cable through the feed arm and connect the 

cable running through the feed arm to the LNB. Tighten the 
cable until fingertight, and then use a 

7

/

16

 wrench to tighten a 

quarter turn more. Do not overtighten.

17. Slide the LNB into the feed arm, and re-install the two screws 

(removed earlier) through the underside of the feed arm and 
replacement LNB. Tighten.

18. Slide the LNB guard up the feed arm and over the LNB. The 

front of the LNB guard shoud be ~½

 in front of the LNB and 

should not be touching the LNB. Install the four bolts through 
the four holes in the LNB guard. Thread a nut onto each bolt, 
and tighten. 

19. Slide the new reflector on to the lower hooks of the bracket, 

ensuring that the upper holes on the reflector line up with the 
upper holes on the reflector bracket. Insert two bolts through 
the upper holes on the front of the reflector through the upper 
holes on the bracket. Thread a nyloc nut on each bolt, and 
tighten the nuts.

WARNING:

 

Do not use old reflector hardware to install new reflector. 

Failure to use new bolts/nyloc nuts can lead to property damage, personal 
injury, and/or death.

20. Plug in the interface box. Press and hold “POWER” for two 

seconds to turn on the interface box. Press “POWER” again to 
stow the antenna.
