SatMax Triple LNB holder

Fitting instructions

 

The Triple LNB holder is designed to be used on systems receiving Optus satellites D1 at 160E, C1 at 156E and B3 at 152E.  It will only work with LNBs that exhibit vertical polarisation when mounted flat as shown below. 

It is specifically designed to suit the PBI  LNBF.

 

It is suitable for use with most KU dish types of 80 to 90cm in diameter.

It was designed for the Triax TD88 and Hills 80cm“off set” dishes.. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Mounting

Absolute accuracy is essential when mounting the Dish mount.

If it is not vertical do not expect to set up this system.

It will not work.

 

1.  Mount LNBs on the holder as shown in the picture.  Do not over tighten the “F” connector nuts or you will destroy the LNB.

 

2. Connectors pointing downwards.  The LNB holder must be connected to the centre LNB. 

 

3   Connect your field strength meter to the centre LNB and a-line your dish to the Optus C1 satellite

(70 dBuV is typical).  TP 12407GHz.

 

  • If you are using a 10.750Ghz LNB then your L band IF is 1657GHz.
  • If using a 11.300GHz then your IF is 1107 GHz.

 

4  Connect your field strength meter to the left hand LNB and move the LNB upward for maximum signal on B3

(about 30 degrees from horizontal).  (70 dB uV is typical).

 

 

  • Use TP 12525Ghz and an IF of 1775Ghz using a 10.750LNb

 

5    Run the three cables to  a four way DiSEqC switch and programme your receiver to the appropriate satellite LNB port “A” or “B” or “C” or Port 1,2,3 as necessary.

 

6    The STB is usually set so that

  • D1 is DiSEqC port 1,

  • C1 is DiSEqC port 2

  • B3 is DiSEqC port 3

 

7    Make sure that the STB is switched off whilst connecting the LNBs.

       Damage will be caused to the DiSEqC switch if you do not do so.   The warrantee is void if this found to be the case.

PLEASE NOTE IF YOU ARE USING A TRIAX MULTI BLOCK  A GOOD SPECTRUM ANALYZER or EXPERIENCE IN MULTI SATELLITE SYSTEMS IS NEEDED  But If you understand the principles of the above then you should be able to set the Triax multi block correctly.
