For ex galaxy Pacific Monolithics and Hills integrated downconverters.
Make a crossways cut on the old galaxy cable connector, and use a flat
driver to remove it. You may need to loosen nut first.
Unscrew the screw near the LNB, and put it somewhere safe
Slide the LNB out.
Split the LNB at the
narrow end; don’t
worry too much about being neat, you will be butchering this end later
cable anyway. Work the seam open to
the other end, if the seam refuses to split a few solid hits with a
shaped hammer or the back of an axe along the seam at the narrow end,
later on the curved part), should crack the seam a little, allowing you
pull it apart with your hands.
||4. Remove the
circuit board, and take off the
smaller radiation shield and put it somewhere safe.
Drill the 2 rivets holding the die cast metal out at the pickup end.
rivets on the wide end of the board) Don't drill any more out.
||6. Get a hack saw and cut off about half a
the die cast metal. If you drilled the holes out, the die cast end
off. Keep cutting into the track underneath until you see silicon, but
further. You need the rest of the board intact so it sits in the LNB
This is Optional, but I recommend doing it anyway, as it makes the
much more neatly; grind off the
components on the side that you removed the smaller
radiation shield from
(this will allow
cable to fit hopefully).Even if you
don’t grind them off, cut any
tracks leading to the little metal square at the wide end (where the
are) to the rest of the circuit.
Solder the CORE of the cable you intend to use to the little "square"
of metal on one side of the wide end of the board. (if you hold the
board up to
the light you will see it links via a hole to one side of the antenna
pickup) I have been told that you
should use silver solder if possible.
Solder the outer cable or "braid" to the other pickup.. you should be
able to make use of one of the rivet holes you drilled out earlier..
|| 10. line the cable up along the narrow end
of the board, and clip the
radiation shield you removed
earlier over it again to hold the cable in
11. drill or file a hole on the back of the
LNB casing, and feed the cable
through and replace the LNB casing over the circuit board. Very Tidy if
12. Use a small piece of masking or packing
tape to hold the two halfs together,
or just a clamp, and run silicon sealer along the seam, and all around
cable where it exits the LNB casing. May also want a little where the
antenna connector screws in.
|13. Feed your wire back through the
antenna's square tube, and slide the
LNB back into the antenna. (if you have a connector on cable already,
need to remove the square pipe to do this as the bracket's screw gets
|14. Re-attach the screw you removed
earlier, and screw the old cable
connector back into the antenna. you
may want to fill the end of the old antenna connector with silicon too
to keep water out.
|15. unless you added one already, attach
your plug to the end of the cable
that should be sticking out the back of the antenna now.
|16. Check all the screws are on properly
etc. Use your new antenna ;o)
