2、銷使工具便于裝在工具套中,同軸電纜施工工具剝線,Stripping coax F-style,45-262 Stripmaster,45-524 Coax Stripper,30-433 Combo Tool,同軸電纜施工工具剝線Coax Stripmaster,Spring action grips & strips Speeds up 2-step stripping Different blades for: RG6 RG59 RG6 Quad,45-262,同軸電纜施工工具剝線Stripping coax with the Stripmaster 45-262,1. Place cab

3、le in smaller hole ” protruding,2. Squeeze handles together firmly & quickly,3. Place cable in larger hole ” protruding, squeeze,4. Stripped cable,同軸電纜施工工具剝線Stripping with the Coax Stripper 45-524,1. Set sliding window to cable size,2. Place cable in stripper with 1/8” protruding,3. Rotate stripper

4、in direction of lettering,4. Remove cable from stripper,5. Remove slugs,6. Stripped cable,同軸電纜施工工具剝線Adjusting the Coax Stripper 45-524,4. Check by restripping cable. What was the left side is now the right side upside down!,1. Remove hex wrench from handle,2. Turn stripper over,3. Insert wrench into

5、 adjusting grommets. Adjust by rotating 1/3 of way around at a time,同軸電纜施工工具剝線Replacing the blade cassette,Pull front door open Lift cassette up & out Insert new cassette & close door,同軸電纜施工工具端接About “F” Connectors,One-piece Most preferred, easiest installation Two-piece More pullout strength Twist-

6、on What twists on will twist off,The number one cause of video distribution problemsis tightening F connectors finger tight. Tighten them with an F connector tool.,同軸電纜施工工具端接 About “F” Connectors,Must be used for all open CATV outlets Eliminates leakage and ingress, which lead to poor signal quality

7、,同軸電纜施工工具端接F-Connector Tool,Using leverage to install an F connector will seat every connector properly Most video signal problems are caused by loose connections. Tighten all connectors with an F-Connector tool.,35-046,Thread connector onto end of tool,Push connector onto stripped cable,同軸電纜施工工具端接C

8、oax Strip & Crimp Tool,Cuts, Strips & Crimps RG-6 & RG-59 No need to carry separate tools Good for occasional contractor use,30-433,同軸電纜施工工具端接Terminating coax - CrimpMaster,Consistency & repeatability More leverage, less installer fatigue The same crimp every time 28 interchangeable dies For the ins

9、taller with more than an occasional crimp to do,30-506,與Crimpmaster 配合使用的同軸電纜連接器壓接模塊,同軸電纜施工工具剝線Stripping coax - BNC,Accuracy, efficiency, repeatability,45-520 Coax Stripper,Cut center conductor with35-060 CenterConductor Cutter,同軸電纜施工工具剝線To use the 45-520,1. Set sliding window to cable size,2. Place
