How to do-it-yourself on renewing an antenna's coaxial (shielded) cable connection. Transcript provided for the hearing impaired: Alright so today on Repairs101 I've got a frayed piece of coaxial cable on a two-way radio antenna that needs repairing. OK so here's the deal: coax is used on electronics like two-way radios, radar and something called television. Now here's a sample I put together, really the tip should be soldered as well as the shield should be soldered to the fitting. This is what a bad installation looks like. I guess he was in a hurry or something, I don't know. So I cleaned it up and I dismantled it. I had a heck of a time getting this plug out. (There it goes!) Obviously the wire needed to be fresh-ended. So I marked the wire for the core and the shield -- just the same as the old wire. Once the end is prepped you want to slip on a shrink tube. Next I took a terminal and I bent the ring back and then I spread apart the saddle a little bit. I put it all together and spread the shield away from the dielectric. Be sure your dielectric is cut so that it's flush to avoid any signal leakage. I trimmed the ring off, then I gave the saddle a real good squeeze. Then a little solder here, a little solder there. A little solder there, too. So then shrink tube, two layers thick. And then last but not least was this little plug that I stuck on with some silicone. Finish up with a continuity test from the antenna to the core and again from the fitting to the base. Alright, thanks for watching and don't forget to subscribe!
