Full transcript

1. 0:00in this video we're going to take a look
2. 0:02at how to install a crimp style BNC
3. 0:04connector on some rg8 colax the same
4. 0:07connector will fit a wide variety of
5. 0:09different coax types that are all about
6. 0:11the same dimensions of
7. 0:13rg8x the items needed will be the
8. 0:16connector of course the coax uh couple
9. 0:19of pieces of heat shrink tubing I've got
10. 0:21some 1/4 in and some 3/8 in here that
11. 0:23we'll use uh pair of proper uh crimpers
12. 0:27we'll talk about that in a moment uh a
13. 0:29pair of cutters an exacto knife or maybe
14. 0:31if you've got a coax trimming tool and
15. 0:33then some heat source to uh to shrink
16. 0:36the heat shrink tubing when we're all
17. 0:37done now the first step is to slide the
18. 0:40heat shrink tubing and the Crim sleeve
19. 0:42on the coax before you get started next
20. 0:45we'll prepare the end of the coax by
21. 0:46trimming the outer insulation the braid
22. 0:49and then the inner insulation to meet
23. 0:51these Dimensions now keep in mind that
24. 0:53these Dimensions really apply to this
25. 0:56particular connector from this
26. 0:57manufacturer here uh and supplier from
27. 1:00Max gain systems uh always be sure to
28. 1:02follow the instruction sheet for the
29. 1:04connector manufacturer that you're
30. 1:06buying the connectors from because the
31. 1:08dimensions May differ because the
32. 1:10connector designs May differ I typically
33. 1:12start just by arbitrarily going back a
34. 1:14little bit further than I need to and
35. 1:17trimming the outer insulation here first
36. 1:19and then working my way toward uh
37. 1:21towards the end of the coax and then
38. 1:22trim the final Center connector uh at
39. 1:25the very end to me that makes it a
40. 1:27little bit more logical sense to try to
41. 1:28keep track of all the dimensions
42. 1:30with the end of the coax prepared
43. 1:32properly the next thing we want to do is
44. 1:33attach the center pin the center pin can
45. 1:36be attached either through crimping or
46. 1:38through soldering soldering is generally
47. 1:40more recommended that's what I'm going
48. 1:41to do here apply some heat to the back
49. 1:45side of the
50. 1:46connector and put a little bit of solder
51. 1:48through the visible wheat pole up here
52. 1:51and doesn't take much once you see a
53. 1:53drawing into the hole you're basically
54. 1:55done now make sure that uh you don't
55. 1:57have any excess solder on the outside
56. 2:00body of the center pin here that might
57. 2:01prevent you from inserting it properly
58. 2:03into the body of the connector and also
59. 2:05take a note there's a little bit of a
60. 2:07groove right here and uh when you insert
61. 2:09this center pin into the connector
62. 2:11you'll actually hear a click when it
63. 2:13gets inserted all the way so again that
64. 2:16you got to make sure that's perfectly
65. 2:17clean doesn't have any solder or flux
66. 2:19left in it now you can uh kind of rotate
67. 2:22around the uh center pin in the center
68. 2:24insulation to spread out the shield so
69. 2:26that it goes on the outside of the
70. 2:27crimping surface here and insert the
71. 2:30connector in place again you want you
72. 2:33want to push firmly till you hear that
73. 2:35click I typically like to push it down
74. 2:37on the table this way so I can actually
75. 2:38hear that click
76. 2:40happen right next we take the crimping
77. 2:42fural and slide it all the way up over
78. 2:45the breed and completely cover it make
79. 2:48sure you don't have any stray ends
80. 2:50sticking out too far if you do you can
81. 2:51trim them off and we get ready to crimp
82. 2:54now when it comes to crimping the feral
83. 2:56again you want to follow the
84. 2:57instructions that you that come along
85. 2:59with the connector and for this
86. 3:00connector we actually want to use a255
87. 3:03in HEX crimp tool and that's what we
88. 3:06have here okay we'll insert the
89. 3:09connector's feral into the crimping die
90. 3:11here and just before we crimp down on it
91. 3:13we'll make sure we're fully seated and
92. 3:16we'll bear down on this and make the
93. 3:19crimp that completes the installation of
94. 3:21the connector I'm going to add a little
95. 3:23bit of heat shrink tubing to seal off
96. 3:25the end of the connector and act as a
97. 3:27little bit of a strain relief on for the
98. 3:30end of the connector here right the
99. 3:32first step I put on here is a quarter
100. 3:34inch heat shrink and I've got a little
101. 3:36uh butane uh soldering iron here with a
102. 3:40blue tip on it that I'll use to shrink
103. 3:42the tubing around the coax and the
104. 3:47connector next I've got some 38 I'm
105. 3:50going to put on here this might be a
106. 3:51little large let to see if it shrinks
107. 3:53all the way down if it doesn't I will
108. 3:54just uh remove it but it looks like it
109. 3:57may do okay here this just adds another
110. 4:00little bit of uh strain relief here to
111. 4:03where the coax meets the connector
112. 4:05itself and that completes the
113. 4:07installation of this Crim style BNC
114. 4:09connector from Max gain systems onto
115. 4:12this rg8x coax
