1.0 Health and Safety for Operators and Installation Staff

Prior to installation, verify that the installation site and supporting structure have been

investigated and found capable of withstanding all loads imposed by the proposed antenna

system, equipment and personnel. It is highly recommended that a RISK ASSESMENT is

carried out prior to the deployment to ensure the safe working area for everyone and the

risks have been reduced.

Working at Height – a brief guide http://www.hse.gov.uk/pubns/indg401.pdf

Risk Assessment – a brief guide http://www.hse.gov.uk/pubns/indg163.pdf

The TP100 has been designed as a ‘no-tool’ assembly, this results in moving

parts that could cause a finger trap. These are pointed out through-out this

manual.

Do not stand in front of the antenna whilst the system is operating. Do not

look into the feed system whilst the system is operating.

Due to the single case design the transit case is a 4-man lift

secure the feed arm stays to the feed carriage

Repeat both sides of the feed carriage

Offer the feed arm up to the underside of the reflector

Tighten all Thumb nuts so that there is no movement of

the components.

Assembly Tip:

Make sure you attached the feed to the

feed arm stays before you fix the feed

arm to the base of the antenna

OP-080316-E1 page 14

The antenna is now ready for pointing

OP-080316-E1 page 15

Appendix A – Pointing with MPAD1 PLUS and ODU Modem

Alignment with the satellite is obtained by setting polarization, elevation, and azimuth angles

which will be automatically displayed on the ‘M-PAD1 Plus ’ hand held unit.

“As a precaution/ backup, charts are provided in this manual to determine the values for your

earth station antenna site. “ΔL” is the difference between the earth station antenna site

longitude and the satellite longitude. Use “ΔL” and your earth station latitude to obtain

polarization, elevation or azimuth setting”

1. Power ON the Modem (the modem will take 1-2 minutes for Boot up)

Power ON/OFF Button

“Modem Booting Please Wait” will appear on

the M-PAD1 Plus whilst the modem is booting

OP-080316-E1 page 16

Once the Modem has booted and the GPS has locked the M-PAD1 Plus will display a T-AZ

& T-EL (the “T” standing for target angle). The target AZ & EL will be the position of the

satellite from your location.

The Polarisation will be displayed as Receive POL (i.e. this is the polarisation of the receive

carrier coming from the satellite)

2. Polarization of Feed

NOTE: you must know the Polarization you are receiving (Horizontal or Vertical, this

will be given to you by your satellite operator)

Loosen feed Horn clamp bolts and turn feed clockwise or counter-clockwise, depending on

the value calculated by the M-PAD 1 Plus hand held device.

Alternatively set the POL angle, east or west of the satellite as shown on Chart 1.

OP-080316-E1 page 17

3. Elevation - Initial Setting

The QDV120 is fitted with a pre-calibrated oil filled terrain compensation inclinometer (which

is mounted on the Elevation Head. The inclinometer has been set to compensate for the off-

set of the reflector.

The M-PAD 1 Plus will display the calculated elevation angle

Course Adjust Fine Adjust

Step 1. Release the top locking nut (could be

brass or hand nut depending on model)

Step 2. Rotate the locking nut to give rough

travel required to move the reflector to desired

elevation

NOTE: You can manually move the reflector

Step 4. Use the lower hand nut for fine

adjustment

Step 5. Secure the top locking nut

NOTE: for peaking you will need to release the

locking nut

OP-080316-E1 page 18

4. Azimuth - Initial Setting

The M-PAD 1 Plus will display the calculated Azimuth angle

Azimuth refers to the rotation of the whole antenna around a vertical axis. It is the side to side angle. The QDV120 azimuth mechanism will allow you to loosen the main mount bracket and swing the whole dish all the way around in a 360 deg circle.

By definition North is 0 deg, East is 90 deg, South is 180 deg and West is 270 deg. North can also be called 360 deg.

Course Adjust

Step 1. Release the locking levers (X2) one on

each side

Step 2. Release the four azimuth clamps on the

bottom of the AZ/EL head.

NOTE: these could be over centre clamps or

hand nuts depending on model number

Step 3. Set the look angle as denoted on the M-

PAD 1 Plus by moving the reflector with your

hand (using a compass)

Step 3 . lock off the reflector with lock levers (X2)

NOTE: leave the X4 bottom clamps loose until

final pointing

OP-080316-E1 page 19

5. Azimuth – Fine Adjustment

Note: that you find a satellite by pre-setting the elevation accurately and then swinging the whole antenna boldly in azimuth till the signal locks up - so an approximate azimuth angle is normally sufficient.

Inclinometer

Elevation fine adjust nut

Elevation locking nut

Azimuth fine adjust nut

Once the antenna is peaked then secure the X4 Azimuth clamps on the bottom of the

AZ/EL head

OP-080316-E1 page 20

6. Antenna Pointing Procedure (peaking)

Start with the azimuth direction and swinging the dish either side of the satellite till you lose

the signal. You need to identify two points on either side where the signals are down by

exactly the same amount (on your meter) and then put the dish in the exact centre.

NOTE: on the M-PAD1 Plus the lower signal strength bar is the MAX signal strength that has

been achieved, it will hold for a few seconds.

This can be achieved by using the fine adjust lead screw on the AZ’EL head (see section 5)

After setting the azimuth with the fine adjust, tighten the X4 locking clamps on the bottom of

the AZ/EL head. This locks the azimuth setting but will often simultaneously increase the

elevation angle, so you may temporarily lose the signal.

Elevation adjustment is best done with the bottom hand nut nut while allowing the weight to

keep tight contact (no backlash). Count the turns while moving from one low measurement

to the same low measurement. Then turn the nut accurately back to the middle position. Do

it accurately to 1/6th of a turn by counting the knurls on the hand nut.

Polarisation adjustment normally needs assistance from the network hub. The hub can

switch your transmitter on and make it transmit a continuous wave (CW) un-modulated clean

carrier on a frequency where it is unlikely to cause interference to other satellite services.

Your antenna is ready to transmit.

OP-080316-E1 page 21

7. Setting the satellite orbital slot

The orbital slot can be set from -180 to +180 (- is

locations West of South, + is for locations east of

south)

Remove the rear cover of the M-PAD1 Plus to expose the internal PCB.

To adjust the orbital slot press the ‘+’ and ‘-‘ input keys (reading on the front screen will

change) once the desired orbital slot has been selected press the ‘SAVE’ key

8. Dip Switch Selection

The MPAD has a logic circuit to allow you to select linear or circular POL.

Down UP

EL X Elevation off set

EL X Normal screen

POL X Linear (Ku-Band)

POL X Circular (no polarisation displayed on front LCD)

10 X Sets POL Mode to C0- POL (Vertical Rx pol =

OP-080316-E1 page 22

0)

10 X Sets POL Mode to Cross- POL (Horizontal Rx pol = 0)

A6 Not Used

Polarisation mode selection

Pin Mode : POL Down Linear

UP Circular

In the up position the MPAD2 will be set to circular polarisation, no POL skew angles

displayed

In the down position the MPAD2 will be set to linear polarisation, the POL angle for the

desired satellite will be displayed on the front LCD for both Horizontal and vertical RX.

Cross Polarisation mode selection

Pin Mode : 10 Down Cross POL Vertical Rx =0

UP Co-POL Horizontal Rx =0

Pin mode 10 switches between H pol at 0 deg & V pol at 0 deg. Switch up is H at 0 which

will relate to Co-pol on the 5W TRIA fitted and with the switch down it is V at 0 which will be

Cross-pol for TRIA & normal operation for most beams.
