 UHF type (clamped screen) PL259

1. Cut end of cable even. Remove vinyl jacket 3/4in.
   Slide coupling ring and adapter on cable.
    
2. Fan braid slightly and fold back as shown.
    
3. Position adapter to dimension shown.
   Press braid down over body of adapter and trim to 3/8in.
   Bare 5/8in of conductor.
   Tin exposed centre conductor.
    
4. Screw plug sub-assembly on adapter.
   Solder braid to shell through solder holes.
   Use enough heat to create bond of braid to shell.
   Solder centre conductor to contact.
    
5. For final assembly, screw coupling ring on plug sub-assembly.

UHF type (soldered screen) PL259

1. Cut end of cable even. Remove vinyl jacket 1 & 1/8in.
    
2. Bare 5/8in of centre conductor. Trim braided shield.
   Slide coupling ring on cable.
   Tin exposed centre conductor and braid.
    
3. Screw the plug sub-assembly on cable.
   Solder assembly to braid through solder holes.
   Use enough heat to create bond to braid to shell.
   Solder centre conductor to contact.
    
4. For final assembly, screw coupling ring on plug sub-assembly.

N type

1. Cut end of cable even and remove 8.73mm (11/16in) of outer sheath.
    
2. Slide the clamp nut and pressure sleeve over cable.
   Comb out the braid.
    
3. Fold out braid back.
   Insert the ferrule between braid and dielectric.
   Trim off excess braid.
   Remove 5.55mm (7/32in) of dielectric without  damaging the inner conductor.
   Tin end of conductor.
    
4. Slide rear insulator over conductor and position against end of dielectric.
   Slide the male contact over the conductor until the shoulder of the male contact is pressed hard against the rear insulator.
   Solder the male contact to the conductor but avoid over-heating.
    
5. Fit front insulator in body and push sub-assembly into the body as far as possible.
   Slide pressure sleeve into body screw in the nut clamp tightly to clamp cable.

BNC type (male contact)

1. Cut end of cable even and remove 7.93mm (5/16in) of outer sheath.
    
2. Slide the clamp nut and pressure sleeve over cable.
   Comb out the braid.
    
3. Fold out braid back.
   Insert the ferrule between braid and dielectric.
   Trim off excess braid.
   Remove 5.16mm (13/64in) of dielectric without  damaging the inner conductor.
   Tin end of conductor.
    
4. Slide rear insulator over conductor and locate shoulder of insulator inside recess in ferrule.
   Slide the male contact over the conductor until the shoulder of the male contact is pressed hard against the rear insulator.
   Solder the male contact to the conductor but avoid over-heating.
    
5. Fit front insulator in body and push sub-assembly into the body as far as possible.
   Slide pressure sleeve into body screw in the nut clamp tightly to clamp cable.

BNC type (female contact)

1. Cut end of cable even and remove 7.98mm (5/16in) of outer sheath.
    
2. Slide the clamp nut and pressure sleeve over cable.
   Comb out the braid.
    
3. Fold out braid back.
   Insert the ferrule between braid and dielectric.
   Trim off excess braid.
   Remove 5.16mm (13/64in) of dielectric without damaging the inner conductor.
   Tin end of conductor.
    
4. Slide rear insulator over conductor and locate shoulder of insulator inside recess in ferrule.
   Slide the female contact over the conductor until the shoulder of the male contact is pressed hard against the rear insulator.
   Solder the female contact to the conductor but avoid over-heating.
    
5. Fit front insulator in body and push sub-assembly into the body as far as possible.
   Slide pressure sleeve into body screw in the nut clamp tightly to clamp cable.
