How to Install a PL259 Marine Antenna Connector on Marine CB Antenna

Dec 15, 2015

Our marine CB antenna with mount and standard marine CB antenna have PL-259 connector at their end. How to Install a PL259 Marine Antenna Connector on Marine CB Antenna? Watch the vide below for details:


Three ways to install a VHF radio antenna connector.

One of the most tedious painstaking jobs of installing a VHF radio antenna is the connector. First, go through your checklist to make sure that all the parts are there for your connector assembly. In the pack is the brass washer and Teflon spacer, the connector body itself, the coupling ring itself, the reducing adapter, and the cable strain relief.

Method 1: Solder.

We're going to put our strain relief on the cable, and then we will follow that with our reducing adapter and then our coupling ring. The threads have to be facing the end of the cable. Cut outside jacketing, making sure that you don't nick any of the braid to an inch and a half from the end, and just take this part of it off. Cut the braid and the dielectric back one inch from the end, and then remove it. Dielectric is the inside insulation between the braid and the center wire. Next, take this braid and fan it out, and then fold it back over our reducing adapter. Now, for those that don't want to solder through these little holes, which is the most difficult part of this connector, we have actually also included Teflon spacers and brass washers that cause a compression fit on this braid so that you don't have to solder it. So you take your brass washer and you put it on first, and then you put your Teflon spacer on.

Method 2: Limited Solder.

The solder holds the braid in place. Since we're proficient in our soldering, we're just going to solder this particular connector. We're not going to use these brass washers and Teflon spacer, just put on the connector body just and make sure that the center wire goes all the way through the end. Then screw on the back end. Be careful not to fray the end of that as you're trying to put it through. We're going to solder on the tip with our soldering iron to hold the center wire in place. And then put some solder on each one of these holes on the outside to hold those in place. We will use standard rosin core solder because this works the best for our application. After we finish doing our soldering, all we simply need to do is come to the end and cut off that extra little wire, and then we start assembling our connector body. So screw back on our coupling ring, and it goes all the way on and then becomes also the connector that hooks into the input. Then we' will just slide our strain relief onto the back end, and our connector is complete.

Method 3: Coax.

This connector is really easy to install. All you need to do is just cut your coax off flush just like that, and that is it for the prepping as far as the coax goes. Then you just take your coupling ring and put this onto the coax, just like this. Then you will just push the connector in. Take your standard pair of pliers and crimp on the back. Those have teeth in them that bite into that cable, and that is how it actually pierces through the jacketing to make contact with the braid. Then you just screw on the back end of your connector, and your connector's complete.

Now, that can't be easier. These're the three easy methods to take away all your connector pain.

  • Watching this video makes me think one thing: I want a boat. After a year of being stuck in the house I’m ready for some summer fun. Even a small passenger boat would be cool. Good information on the CB antenna too but I’d also get a cell phone booster for my boat. Why not make sure you get a good cell signal, even if it’s to make reservations at a restaurant with a dock?
