The ONX-CATV has two RF ports with field
replaceable barrel style connectors. The ONX ships
with two F- 81 splice style adapters rated to 3 GHz.
These F-81 adapters are 1.2 in (307mm) long with
a 0.5 in (132mm) distance between either end and
the tightening nut. They are shipped installed into
the RF ports to the recommended torque

After some use these F-81 adapters may need to
be replaced. When replacing these adapters, an F-
