LNB-1 Without Filter (Kit 72-0790)
To convert an antenna with a serial no. between
150800890 and 170100021 to a V7-HTS antenna
,
follow the steps below.
1.
Using a 7/16" open-end wrench, disconnect the
RF cable from the LNB (see Figure 9). To avoid
stressing the cable, hold the top of the connector
with your fingers while loosening.
2.
Using a Phillips screwdriver, remove and
discard the four M4 screws securing the LNB to
the OMT (see Figure 9). Remove the LNB.
3.
Make sure the rubber O-ring is pressed into the
groove of the new LNB’s mounting surface (see
Figure 10). Then secure the new LNB (KVH part
no. 19-0982-01) to the OMT using four new M4
screws (KVH part no. 14-0075-10N), making
sure that the LNB notch faces the OMT as
shown in Figure 11. Tighten the screws to
approximately 21 in.-lbs (2.4 N-m) of torque.
4.
Remove the protective cap from the LNB’s RF
connector. Then connect the RF cable to the LNB
making sure that the RF cable is aligned to
prevent any interference when the feed
assembly rotates (see Figure 11). Hand-tighten,
then tighten with a 7/16" torque wrench set to
15 in.-lbs.
