Learn how to effortlessly connect a BNC connector to an RG59 coaxial cable with our step-by-step guide. From tools to safety tips and troubleshooting, we cover it all!

It's a beautiful day, you've got your cup of coffee ready, and you're all geared up to install that CCTV camera or set up your amateur radio station. But wait, you've got to connect a BNC connector to an RG59 coaxial cable first! Don't fret, this task isn't as daunting as it seems. With a little bit of practice and patience, you can pull it off like a pro.

What You'll Need: Tools and Materials

Before you embark on this miniature voyage of electrical craftsmanship, make sure you have all your essentials at hand:

  • RG59 Coaxial Cable
  • BNC Connector (Crimp or Compression Type)
  • Wire Cutters
  • Coaxial Cable Stripper
  • Crimping Tool (if you're using a crimp-type connector)
  • Compression Tool (if you're using a compression-type connector)

Safety First!

This is electricity we're talking about; it doesn't take kindly to mistakes. So remember, unplug any device the cable is connected to and put on safety goggles. Safety is the cornerstone of all great DIY adventures!

Step 1: Measure Twice, Cut Once

It's an age-old adage but worth repeating. Measure the length of the RG59 cable you'll need, leaving some room for slack, and then cut it using your wire cutters. A clean, straight cut is crucial for a secure fit with the BNC connector.

Step 2: Stripping the Cable

No, this isn't a risqué dance move. You'll need to strip the outer insulation of the RG59 cable to expose its inner conductor and shielding. Here's how:

  1. Insert the cable into your coaxial stripper.
  2. Rotate the stripper around the cable to make a clean cut.
  3. Remove the outer insulation layer, revealing the inner braided shield.
  4. Push back the braided shield to expose the inner insulating layer and center conductor.

You should now see three layers: the braided shield, an inner insulation layer, and a central copper conductor.

Step 3: Fitting the BNC Connector

Crimp Type Connector

  1. Slide the crimp sleeve (part of your BNC kit) over the outer insulation.
  2. Insert the center conductor into the BNC pin until it's snug.
  3. Slip the main body of the BNC connector over the center conductor, making sure the braided shield is between the inner insulation and the connector.
  4. Place the crimp sleeve back into position, lining it up over the connector's end.
  5. Use the crimping tool to crimp the sleeve securely into place.

Compression Type Connector

  1. Slide the BNC connector over the prepped end of the cable.
  2. Push it in until the center conductor protrudes slightly out of the connector.
  3. Use the compression tool to compress the connector, securing it in place.

Step 4: The Test Run

Now that your masterpiece is complete, it's time for a trial run. Connect your cable to the equipment or system you're working on and fire it up. If everything's functioning as it should, give yourself a pat on the back—you've just mastered the art of attaching a BNC connector to an RG59 cable!

Step 5: Troubleshooting

If you do run into any issues, double-check your connections and crimps. If you still face problems, you might have to redo the connector installation. It's all part of the learning curve!

Final Thoughts

There you have it—the ultimate guide to connecting a BNC connector to an RG59 coaxial cable. So go ahead, take that sip of victory coffee. You've earned it!
