Legacy LNB-1 (Kit 72-0797)
To convert an antenna with a serial no. earlier
than 150300409 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 3). 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 4). Remove the LNB.
3.
Attach the new LNB and filter assembly (KVH
part no. 02-2152-01) 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 5. Tighten the screws to
approximately 21 in.-lbs (2.4 N-m) of torque.
NOTE: A filter is added to the new LNB because the
OMT in this serial number range does not include a
built-in filter.
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 5). Hand-tighten,
then tighten with a 7/16" torque wrench set to
15 in.-lbs.

Important!
Before removal, note the LNB orientation (the LNB
notch, shown in Figure 3 and Figure 4, faces the
OMT), and be sure to match this orientation when
installing the new LNB.
