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.

It connects the Skew Assembly to the Mount

10

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.

Hi/Lo Screws

4 Places, (note recessed holes).

Attach to back of antenna by

inserting screw through these

holes from this side.

Button Head Bolts

4 Places, note that this bracket

will be attached to the mount

first and then using the button

head bolts fasten the antenna

from the front side to the bracket

with bolts provided.

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
