WS International DMX741 Installation Manual

Digital C & Ku 13V/18V LNBF with Standard Ku
Congratulations on purchasing a new WS International DMX741 CKU band LNBF. This LNBF is com-
patible with your standard Free To Air satellite receiver and your 4DTV C band receiver. Please
note, to use this LNBF with your 4DTV satellite receiver, please do not use jumper cable supplied.
Please run a separate Ku line and a separate C band line to your 4DTV satellite receiver.
Your new LNBF should include the following:
Hardware Pack — Used to attach the CKu LNBF to the scalar ring and to attach the scalar ring
•
to the LNBF support arms of your satellite dish antenna.
Scalar Ring — This is used to hold the LNBF on the satellite dish (when using a prime focus
•
dish) and to concentrate the signal into the LNBF.
Coaxial Jumper — This is used to connect the Ku portion of your LNBF to the built in 22KHz
•
switch on the side of the LNBF
Main CKu LNBF — This is your main C and Ku band LNBF. The end connector is your Ku band
•
portion and the side connector marked "RCV" is C band.
Dielectric Plate — Is inserted inside the waveguide of the LNBF to pickup circular polarizations.
•
Please note, you will loose your ability to receive linear polarization while the dielectric plate re-
mains in the waveguide.
Installing your new DMX LNBF:
1. Attach the scalar ring to your prime focus satellite dish using the nuts and bolts supplied. Note,
the scalar ring has multiple holes to fit either a 3 arm or 4 arm prime focus dish.
2. Insert the LNBF into the scalar ring and tighten the bolts very little so it's held in the scalar ring.
3. Decide how you want to wire up your new DMX LNBF. These are your options:
Option
Receive only Ku signal
Ku Only
Receive only C signal
C Only
Receive both C and Ku via 1 coaxial
C/Ku 1-
Coaxial cable using the built in switch
Receive both C and Ku with your
C/Ku Separate
Coaxial 4DTV receiver or external switch
4. Turn the LNBF so that the "0" degree polarity mark is at 12 O' clock or 6 O' clock.
