Replacing an LNB-1
If you have an LNB-1 without a filter assembly,
follow the steps below to replace the LNB-1 with an
LNB-3.
1.
Using a 7/16" open-end wrench, disconnect the
RF cable from the LNB (see Figure 14). To avoid
stressing the cable, hold the top of the connector
with your fingers while loosening.
2.
Cut and remove the tie-wrap securing the RF
cable to the LNB (see Figure 14 and Figure 15).
3.
Using a Phillips screwdriver, remove and
discard the four M4 screws securing the LNB to
the OMT (see Figure 15). Remove the LNB.
4.
Using the 3mm hex key (
supplied in kit
), remove
the four M4 screws securing the filter to the
LNB-3 (see Figure 16). Discard the filter.
5.
Make sure the rubber O-ring is pressed into the
groove of the LNB’s mounting surface (see
Important!
Before removal, note the LNB orientation (the LNB
notch, shown in Figure 14 and Figure 15, faces the
OMT), and be sure to match this orientation when
installing the replacement LNB.
Important!
Do not remove the Kapton tape from the LNB (see
Figure 17).
