CB Antenna in Existing Antenna Mount

[pnw]

I know it's probably been discussed, but I can't find the thread through the search tool.

Anywho, I want to install a CB/PA in my kj, however I think aesthetically the antenna looks great mounted on the existing AM/FM antenna.

I found the Wiki article on how to bore and tap. My question is in the electrical. I'm a noob on all the radio stuff.

I'm not sure why the splitter is necessary; also will the antenna still work for my stock AM/FM radio? Also, when using the existing mount, do I use a coax cable? The article makes it seem like I take advantage of existing wiring.

Thanks guys!


**Update**

Did a literally 30 seconds of research to find out what the splitter does. It makes the CB antenna the AM/FM antenna!

I mounted my antenna off the rear tire carrier, used a mount that clamps onto one of the stud nuts from the carrier to the body. A 12ft coax fits from the antenna to under the weather strip on the rear gate, run on the floor to the passenger footwell. My Cobra 29ltd classic is mounted on the plastic on the passenger side of the trans tunnel.

Do you have a pic of how you mounted it to the spare?
