How to mount an N-male connector?

Here you will find a step by step guide to install a GSM, 3G and 4G amplifier. In 4 simple steps, you will mount an N connector easily and quickly. There is nothing complicated, it is simply a matter of respecting the assembly order of the different elements of the N connector. Read more:

 

 

There are two main scenarios in which it is necessary to manufacture your "coaxial cable": either you must wire "to measure" (saving measure or control of signal loss in the cable), or the pre-assembled connector is too thick to pass through an existing conduit or hole.

Each N connector in our range can be attached without crimping. So it is very easy to make your custom GSM booster cable. If you prefer the N crimp connector, it is also available. Contact us about this before placing your order.

 

1. Required tools

Monter un connecteur N

  • - wire cutter
  • - a cutter (practical and burr-free)
  • - a wrench
  • - a flat key

Therefore, it is not difficult to find the necessary tools.

 

2. Cutting and stripping the coaxial cable

 

Monter un connecteur N

Start by cutting the coaxial cable to the desired length for your GSM 3G 4G amplifier. Cut well to make a clean cut. Deburr, if necessary.

Strip the outer jacket of the coaxial cable, 8 to 10 mm from the end. Be careful not to damage the ground wire of the coaxial cable when removing the sleeve!

Prepare the core and braid of the cable, as shown.

Gently sharpen the braid to make the core insulation (the center conductor of the coaxial cable) accessible, then strip the insulation from the center conductor 5mm.

 

3. Preparation of connector N 

This is what a disassembled N connector looks like

It is a good idea to arrange the different elements of the N connector before starting assembly: you will save precious time and make no mistakes in this order:

  • - rear locking screw
  • - pressure washer
  • - rubber ring
  • - cradle for the braid (and its pressure washer)
  • - contact insulator for core tip
  • - peg
  • - main body of connector N

 

4. Mounting the N connector on the coaxial cable

You can now proceed to assemble the elements, following the order of the elements listed above.

Instead of a long speech, just follow the steps in the images:

And here is the end result, once the connector is locked:

Note: The tip of the core must be soldered to ensure good contact. A weld will prevent the development of oxidation between the core conductor and its tip , especially in the long term. This step is not illustrated in images.

Once all the elements are assembled, it remains to lock everything by aiming the rear screw on the main body of the N connector. Use the open-end wrench and adjustable wrench to do this. No need to force the fit - when the fit becomes blocking (it's a clear feeling), you're good to go.
