Hi, It won't work very well at all.
You can probably still get a CB antenna that looks like a regular
AM/FM car antenna. Not the very best CB antenna in the world but it works
OK
and best of all it looks like a regular antenna.
Good luck and happy motoring!!

I'm new to this group and know very little about CB radios, so please,
no flames! I'm restoring a 1957 Buick Special and want to use a CB in
my car. I'm looking at possibly buying a Cobra 29LTD classic w/ the
supermod upgrade. My only problem is that I don't an antenna showing
on this car. My question is this: If I were to use one of those Helix
coil antennas, and mounted it under the seat, would it work just as
well as a regular antenna on the roof? My theory is that using one of
those helix antennas would compensate for the fact that I'm mounting
it in such a weird location (that is, if location even makes a
difference). Again, I know almost nothing about this sort of stuff.
All I know is that I definately want a CB in my '57 Buick. Any info is
appreciated.
