You'll need this for replacement of an antenna cable

Rich from Chicago, IL on 11/8/2012

Crutchfield Customer Review (What's this?)

Nobody out there manufactures a direct replacement antenna cable with two male ends. You'll need to add this to the female end of an extension cable for proper replacement.

Pros: Works as expected.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

It was included with my Kenwood indash CD unit purchase. [ Carlos  Oct 06, 2018 ]
put a new radio in my 04' Silverado and I needed an adapter to go from the female truck cable to the female port on the new radio. I'm not totally sure this will work but its the only male to male cable I've found so gonna give it a shot [ daniel  Mar 07, 2018 ]
Male snap lock end pulled off factory antenna cable. I was able to find replacement cable from antenna mount to midway junction at passenger door. I was unable to find the second half of the cable from midway junction to radio. The midway junction terminates in a female GM micro/delco connection. I will use the Metra 40-GM20 with GM micro/delco male end to Motorola female end, then add the Metra 40-UV42 adapter with male to male Motorola connectors to make my final connection to the receiver.
