Figure 6-6: Crimping Instructions for TNC RF Connector
When performing the Performance Test procedures presented in Section 15, the
following antenna elements must be field-tuned (trimmed/cut
) for maximum
performance/minimum reflection:
• Part number AN-225002-003 (136 – 174 MHz, 3 dBd) — For length cutting
information, see the instructions included with the element.
• Part number AN-225002-004 (136 – 174 MHz, 2.4 dBd) — For length cutting
information, see the instructions included with the element.
• Part number AN-225006-001 (132 – 960 MHz, 0 dBd) — For length cutting
information, see the charts in Figure 6-7 on page 32, and/or the instructions
included with the element.
Other antenna elements used with the radio are factory-tuned and therefore they do not
require tuning in the field.
NOTE
1. Before cutting the cable to a shorter length, refer to the previous
WARNING. Some antenna cables should never be cut, while others
can be cut to as short as 6 feet.
2. Trim the end of the cable to the dimensions shown at the left, taking
care not to nick the cable’s inner conductor or its braid/shield.
3. Slip the crimp sleeve over the end of the cable, with its flanged-end
facing towards the end of the cable.
4. Place the contact onto the cable’s inner conductor. The end of the
contact and the cable’s inner die
lectric must “butt square” together, as
shown to the left.
5.
While holding the contact tight against the dielectric, crimp the contact
to the inner conductor using an appropriate crimp tool.
6. Flair the cable’s outer braid/shield and then gently but firmly push the
contact (and cable end) into the connector housing until a gentle snap
is felt, indicating the contact is locked in place.
7. Slip the crimp sleeve in place, butting its flanged-end against the
connector housing.
8. Using an appropriate crimp tool, crimp the crimp sleeve securely to
the cable end and connector housing. When crimping, hold the
housing and sleeve firmly together, and to the cable end.
