CAUTIONS:
INSTALLATION POLE HEIGHT
The pole must be tall enough that the dish face will clear any structure or
obstacle that it may encounter. Restriction of the movement in such a
manner could cause damage to the dish face, mount or both. It is up to the
installing personnel to assure that proper clearances are maintained.
MOUNT ALIGNMENT
IMPORTANT!! Before tightening the mount bolts to the installation pole,
go to your HTML screen and select “Calibrate Dish” (See Calibrate Dish in your H3
Operating Manual under “Advanced Functions”.) Following a completed
“Calibrate Dish” rotate the whole mount on the installation pole until it conforms
to the instructions below. Once this operation is complete, tighten the Mount
Retaining Screws. This will secure the MESA HPX mount to the pole. Face the reflector
EAST for NORTHERN Hemisphere
WEST for SOUTHERN Hemisphere
5
Attaching the Mount to the Mounting Pole
Step 2
When placed on the fixed Mounting
Pole, the MESA-HPX Motorized Mount
should be in this approximate position.
From this position it will be easier to
attached the Antenna, Feed Assembly,
and run the cables as required.
To secure the MESA Mount to the
Fixed Pole remove all six Cap Screws
from the 3.5” MESA Pole Base. (Red
Arrow)
Orient the mount in accordance with
the instructions given in “Caution”
section of this manual and then insert
2 of the Securing Screws (Blue Dot) and
tighten securly. This step squares the
outer pole to the inner pole (levels).
Now replace the remaining 4 Securing
Screws into the MESA Mounting Pole
and tighten.
6
ATTACHMENT OF THE ANTENNA TO THE MOUNT
Step 3 (For Prodelin Dish suggestions see Appendix A)
Attach the Antenna to the MESA mount using the hardware supplied by the Antenna manufacturer in
the locations shown by the (Red Arrows). (4 locations)
Attach the Antenna short arm brackets (if supplied) to the MESA Mount using the hardware supplied
with the MESA Mount in the locations marked by (Yellow arrows.)
Assemble the Dish RF Arm Assemblies as per the Antenna manufacturers instructions using their
supplied hardware.
7
Mounting of the Feed Assembly
Step 4
Pre-grease with low temperature synthetic grease the Feed Assembly where the two Feed Clamps join
together (Green Arrow).
Secure MESA Skew Assembly using the Feed Assembly Clamp Screws supplied with the SkyWare
Antenna (Red Arrows).
Secure MESA Skew Assembly Connector Bracket to the SkyWare Side Arm Tube using the screws
supplied with the Connector Bracket (Purple Arrow).
For wiring see Skew Wiring Diagram in this
manual.

Wave Guide Spacer
Place between the Wave Guide and
the Transmitter with “O” ring
towards the wave guide.
The Wave Guide Spacer rests in the cradle supplied by
Prodelin. The retaining ring which is shipped the
antenna must not be used. If used it will cause
binding and prevent the rotation of the wave guide.
9
ROUTING OF THE TX COAX, RX COAX AND SKEW CABLE
Step 5
The RF Skew Assembly rotates 102 degrees Clockwise and Counter Clockwise from the position shown in
the picture below. It is extremely important to allow the Coax Cables enough slack to complete this full
travel without applying any stress to the LNB and BUC connections.
The example shown below is a typical wiring configuration which accomplishes this by Zip Tying the two
coax cables together (Red Arrow) and then attaching the cables to the Waveguide RX Filter (Green
Arrow) allowing a cable loop large enough to let the Skew Assembly travel +/- 102 degrees (204
degrees) as shown.
Skew Assembly with LNB shown in Horizontal Field.
Near the top of the RF Arm secure the Coax Cables and the Skew Cable together (Purple Arrow) using
another Zip Tie.
NOTE: Use dielectric grease or coax sealent to prevent water intrusion into the Coax Cables.

SECURING OF CABLES FROM THE FEED ASSEMBLY
Step 6
Near the bottom of the RF Arm secure the Coax Cables and the Skew Cable together (Red Arrow) using
another Zip Tie as shown.
Step 7
Completing the wiring from this point is critical.
See Pictorial Illustration on next page.
You should start your cable runs from the LNB/BUC/Skew Assembly and work down to the bottom of
the mounting pole. This way the cable lengths and all cable loops will be uniform.
Remember that Elevation moves approximately 90 degrees in total travel.
From the lower RF Arm run the cables under to the back of the Antenna and Zip Tie to the bottom of the
Angle Bracket that attaches to the Dish (Red Arrow). Make sure you are tying the Cables to the same
side of the MESA Mount that the Connector Box (Yellow Arrow) is located.
Once you have tied the cables to the Angle Bracket you MUST make a Cable Loop approximately 8” in
diameter to allow for full MESA Elevation travel (Green Arrow).
The Cable Connector Box also doubles as a Cable Clamp for the 2 Coax Cables which will pass through
the connector box and the Skew Cable which will terminate inside the Box.
On the right side of the Connector Box both coax cables and the Antenna Controller Cable will exit
together. Make another Cable Loop approximately 12” in diameter and tie the cable about half of the
remaining pole height from the ground (Purple Arrows) to allow 270 degree Azimuth Travel.

CRITICAL WIRING INSTRUCTIONS
Critical wiring instructions
The MESA Mount Connector Box (Yellow Arrow) serves several functions.
1> Allows easy access to all wiring of Azimuth, Elevation, and Skew motor connections.
2> Simple Controller Cable connections. (Terminal Block)
3> Cable path management to simplify and guide cables.
4> Built in Strain Relief of all external cables.

* The Skew Motor Shares the Azimuth and Elevation connections. To run the Skew Motor, the
controller needs to switch both Azimuth Outputs at the same time to either Pos or Neg Volts
and do the same with Elevation Outputs to the opposite voltage. This will prevent the AZ and EL
Motors from moving when Skew Motor is moving.

inserting screw through these
holes from this side.
Button Head Bolts

Prodelin Antenna Mounting Brackets
PRODELIN 1.2 Meter DISH When mounting the Prodelin 1.2 meter dish it is acceptable to use the provided “High/Low”
screws to attach the dish to the mount. If the dish is expected to be removed several times during the
usage of the system it is “highly” recommended that the “carriage” bolts be used instead. To do that,
follow the instructions below.
Appendix A: Attaching the Prodelin 1.2meter Dish to the MESA 123A
Tools : drill, 5/16 drill bit, socket wrench, ½ inch socket, 9/16 inch socket, 3/16 allen wrench. Included
parts: 5/16 washers (12), 5/16-18 X 2-1/2 button head bolts (4), Hi/Lo 5/16 X 1 1/4 screws, MotoSAT
120HS Prodelin dish brackets (2).
Hi/Lo Screws
These screws are designed to be
installed only once because of the
cutting action of the threads. If the
Antenna is going to be removed several
times this attachment method is not
recommended. They are used in
conjunction with the dish brackets
pictured below.
Button Head Bolts
These bolts are to be used when the
Antenna will be removed often. . They
are used in conjunction with the dish
brackets pictured below.
19
This is a picture of the MESA mount (Prodelin only) that has
the antenna brackets installed waiting for the antenna to be
mounted using the Button Head Bolts. They must be
removed and attached to the back of the antenna if the
Hi/Lo option is used.
20
Preparing the Prodelin Antenna for the option
Using a 5/16 drill bit, drill the holes through to the front of the
dish as indicated.
Insert from the front side of the dish the (4) 5/16-18 X 2-1/2
“carriage” head bolts with (4) 5/16 washers.
The Prodelin dish is ready for installation onto the MESA mount.
Attach the dish to the mounting brackets on elevation mount
plate with the (4) 5/16-18 X 1-1/4 Hex head bolts using (4) 5/16
washers
