How do I change plug on end of antenna?
Permalink  
 

The plug on the antenna doesn't fit the best into my old delco radio.  A few years ago the shop in Anoka S&E checked out the radio and said is tested good.  They gave me a new end to install on the antenna wire.  I just don't know how to do this.  Is it pretty simple?  Thanks

I think it's just a crimpable coax cable.

If you cut back the plastic insulation you should have a braided shielding a nylon inner shielding and the center conductor. The braided shielding gets bent back inside the large connector housing the the center main connector out the front of the tip. I would put a touch of solder on the main connector. Just lightly crimp the housing over the braided shield.

 This is what i say went searching the internet John ; but didn't know if it would work for my antenna cable, since it talked about coaxial cable.

It either has a braided insulation layer or not. If it does not, such as a lot of tv coax, just strip it back and put the center conductor lead in the plug. The idea is that the center conductor can not touch the base of the plug, only the end that goes into the radio. If you look at the end of the connector there should be an insulator separating the male end piece that goes into the radio from the larger plug housing. Hope I explained that clearly. In the attached photo the cable comes into the connector and the insulation is stripped back. The center conductor goes into the tip and is soldered. The coax is then crimped to keep it in place. The red is the insulator that keeps the center conductor from touching the base.

Here is the connector S&E gave me to correct etc a loose fitting plug.  I see the insulation on the end. I haven't cut the old plug off at this point.  But as I understand, I should be able to heat the end to loosen the solder and just pull it off if it's not to tight.

 

no sure how much of the end of the new plug should be crimped.  I imagine you crimp it where the 4 holes are, just enough to help hold the wire in as the solder should help with that.

I have only soldered copper pipe and radiator core in the past.

No connector shown....
If you have enough cable just cut it off.
