FOR A SUCCESSFUL INSTALLATION THERE ARE SIX POINTS THAT MUST BE
CONSIDERED BEFORE ASSEMBLING THE MT-3000AEL.
1.The MT-3000AEL can accommodate main boom diameters of 3” to 5”. If your crossboom is
smaller or larger, the mounting plates may need hole pattern modification. If you plan to use a
tower section as a crossboom, M2 has tower adapter plates available. Call us at 559 432 8873 to
discuss your special needs.
2. Multi conductor cable is needed to supply motor voltage / current and provide position feed-
back information. M2 can supply the required cable or you can purchase the ideal cable from The
Wireman. The ideal cable contains two #12 AWG wires ti power the 28 volt DC motor and two
#22 AWG shielded wires to return the square wave position information to the controller.
3. Tower and mast requirements vary with the size of the array and the environment. Generally,
towers like Rohn 25 or larger are adequate using mast sizes of 2 inch minimum.
4. Mast quality is crucial for large arrays. Do not use 1-1/2” water pipe (1-7/8” O.D.) as it is too
soft. For small 4 Yagi arrays 2: x .180 wall steel tubing is recommended. Tube steel should
meet ASTM 512, 513, or 519 specifications or equivalent. Simply stated steell with a psi rating
over 50,000 PSI ( Pounds per square inch) is required. M2 can supply your mast if no local steel
supply exists in your area.
5. Unless you need a tall mast for other antenna in your system, we recommend that the
MT3000AEL is mounted with no more than 1/2” of mast protruding above the mounting plate. This
will allow the system to rotate the full 180 degrees which aids during assembly and maintenance.
We recommend that no more than 2 feet of mast extend beyond the top of the tower. 3 to 5 feet
of mast inside the tower is adequate. We also recommend a top bearing and a secondary bear-
ing inside the tower above the rotator.
6. The azimuth rotator is also very important in a good installation. Our OR2800PXEL azimuth
rotator is totally compatible with the MT-3000AEL elevation rotator control box and the two control
units link together so only one RS232 cable is required if you use computer control for tracking.
Prop Pitch motors are also good for azimuth rotation and can be controlled using an M2 controller
that is similar to the OR2800 controller but with higher current transformer and motor control cir-
cuitry. Again this PP controller is compatible with the MT-3000AEL controller.
Other possible rotators that could be adequate for you array are:
HDR-300
Tailtwister (T2X)
Ham IV

MT-3000A PRE-INSTALLATION ASSEMBLY
All installations are unique in some way, which means it's OK to preassemble certain hardware, or rear-
range the assembly process to meet specific site requirements. A quick review of the assembly notes
and drawings should help firm up the appropriate strategy. Please remember to double-check all hard-
ware for tightness BEFORE it becomes inaccessible.
PRE-INSTALLATION TIPS AND CONSIDERATIONS:
The MT-3000AEL gear box is shipped dry without oil, see the gear box motor detail for filling instructions. The For
best results, test and calibrate the MT-3000AEL (positioner, cable, and control unit) on a work bench or tem-
porary foundation. This will familiarize you with the components and controls, their proper function, and allow test-
ing of the terminal wiring and connection. Upon completion, the positioner can be run to a known compass or land-

LEVELING BAR ASSEMBLY
The leveling bar is mainly an installation tool to help keep mounting pads parallel during main
cross boom installation.
Depending on your installation, topography & H-Frame type, your leveling bar can be installed in
many configurations. The leveling bar can be removed after installation or left in place as long
as it does not limit your system travel.

CHAIN & IDLER SPROCKET ADJUSTMENT
Excessive chain slop or play may develop after using system for some time. We have incorporated
in a chain adjustment to keep chain slop or play at a minimum.
Please review drawings shown for more detailed information.
To adjust system:
1. Remove the chain cover (Cover not shown on picture above). Position your array where it might
be slightly out of balance so to allow the chain slop to gather between the adjustment idler sprocket
and the large drive sprocket. Loosen the 1/2-13 x Locking nut on the adjustment sprocket slightly.
2. Use a 9/16” socket wrench to turn adjustment bolt.
3. Clockwise rotation of the adjustment bolt will tighten the chain. Adjust the chain to 1/8” of slop or
play. Over tighting the chain can put excessive tension on the idlers and gear box drive shaft.
4. Counter clockwise rotation of the adjustment bolt will loosen the chain.
Note: Over tighting the chain can put excessive tension on the idlers and gear box drive
shaft. A loose chain can allow elevation axis system movement
5.Tighten locking bolts and nuts testsystem. Look for consistent chain tension throughout your sys-
tem movement.
6. After test tighten all hardware and replace cover.

GEAR BOX MOTOR DETAIL
The New MT-3000AEL has been outfitted with a high performance high efficiency gear box
using all roller bearings and gear oil. The gear box has been assembled with a light coat of lubricat-
ing oil. No load testing can be performed during ground set up and test before gear box is filled with
oil. Gear oil should be installed before final installation. SAE 80/90 WT oil has been provided. In nor-
mal operation the motor shaft is only subject to oil splash, a splash seal has been installed for nor-
mal operation. Some oil seepage can occur if the motor is stored incorrectly. See drawing below
for storage position. Be sure to drain oil before storage or shipping.
Filling instructions
Remove oil fill level screw with washer and oil fill plug. Use SAE 80/90 WT oil & fill gear box to oil
level line using the open oil fill level screw hole as a visual guide. Immediately re-insert oil fill level
washer & screw & oil fill plug. Wipe any excess oil.
