Original tri-band antenna splitter?
« on: November 16, 2010, 09:51:07 AM »
I have this box mounted behind the glovebox, attached to A/C-duct.



Is this original antenna splitter (?) for am-fm / cb?

My car ( -79 T/A ) had the tri-band motor antenna option. Was this part of that option? Where are those two plugs on the right supposed to go? What else did this do?

What was "correct" radio-cb combination at-79? I've seen both, separate cb-unit and cb integrated into the radio.

Sami,
Factory was a small silver box with output and input leads.  The original box says delco on it.  At one point had a lot of delco antennas from a former radio shop that I bought out.  If you need a schematic or drawings from GM/Delco sent me your email via PM.  I'll get it to you.  Just give me a day or so.

Thanks for the input.

I believe this is a Delco box as well. I'll try to take it out today evening, we'll see what's in that black label.

OK! Here comes a new picture...



It's a Delco unit made for Genral Motors Corp, made in Japan. Type FCC DATA GM CBD-20 B.

I believe it's part of CB-system, somekind of "brain unit". What do you think?

Looks like a dealer installed unit.  Its not factory.  The factory in 1979 used an integrated CB radio w/Mic and a Am/Fm/CB antenna in which the AM/FM cables and the CB cables were split off into a small silver box.

Yes, I'm sure you are right, thats what I thought also.

Does anybody sell these tri-band power antennas any more. I've seen reproductions of normal power antenna without the cb-coil but I haven't seen any that would include CB.
Or maybe you olds403 still have them in your stock?

That is most likely the cb with the controls in the mic. So unless you can find the special mic you may be SOL

all three cb radio's i have had have that box... the radio was missing from my 80 y84, but that box was still installed under the map pocket inside the console. and looked like a factory installation.

i have another am/fm/cassette/cb that also has that box...don't know what it originally came in.

i also have an am/fm/8track/cb that has that box, was original equipment in a cadillac...

none of them had the large round type connector though...im pretty sure that was for the mic, with the cb controlls on it like was mentioned earlier...but im thinking for some reason you can substitute an ordinary gm mic in its place.

i see them both for sale on evilbay every once in a while...

Sami, I sent you the details via email.  The CB antenna parts you are looking for have not been available for ~20yrs and not reproduced.  I have NOS Delco old stock of most of them.
