Cables of this type are produced within 2–60 m range of lengths. A non-standard
length cable can be assembled by using special tools manufactured by companies
like AMP, Molex, and others. Assembly is carried out in accordance with the manual
delivered with the tool. In doing this, it is necessary to arrange the twisted pairs
in the connector as recommended. Only the screened cable and appropriate
connectors should be used. The maximum cable length is 100 m, however it would
be preferable to limit the cable length to 30 m if a high quality radar signal is
to be obtained.
External lines to the HF-box are connected by means of coaxial cables with BNC
connectors (plug). If the connection is made to the already existing matched coaxial
line (internal matching in the HF-box is turned off), a tap cable to the HF-box should
have a minimum length (preferably not more than 1 m). With the matching turned
on, however, the maximum length of the cable is determined by the characteristics
of the cable used and may be several hundred metres.
Directions on the Splicing of Category 5 Cable for RJ-45 Connection
Baring of category 5 cables with four twisted pairs is carried out with a special
HT-501 type tool.
The cable is bared for the length of 14 mm from the end of the cable. When baring
the cable, be careful not to cut off the cable screen lead-out (the screening foil is
removed together with the insulation).
Before laying the wires, set the appropriate fixtures on the cable, including RJ-45
connection screen.
The laying of wires in both RJ-45 connectors is identical to that in the standard
“patch” cable.
Before putting on the screen on RJ-45 connector, turn the cable screen lead-out
by 180 degrees so that it is under the squeezed part of RJ-45 connector screen.
Cut off the surplus of the cable screen lead-out.
Having completed operations on the laying of the cable lead-outs and the screening
lead-out, and having put on the screen on RJ-45 connector, crimp RJ-45 connection.
For crimping use a special Molex 69008-1100 type tool designed for the screened
cable with four twisted pairs.
Check cable making by means of RJ-45 link tester.
