ADONIS,

How do you know that the Alternator Whine
is coming in from the Antenna ?
..
Turn the Radio On and the Volume Up so that you can
clearly hear the Whine.
..
Disconnect the Antenna from the CB Radio does the Sound
of the Whine Stop or is it Greatly Reduced ?
+ Then in-fact the Antenna is the Source of your Noise
{Whine} Problem.
- However if the Whine is just as Loud as when the
Antenna is 'connected' then the Problem is elsewhere.
..
Two Possible Elsewheres :
* The CB Radio Ground.
- Recheck your Radio's Case Ground Connection
+ Use a 4"-8" piece of Braided Webbing as a Ground Strap
between the Auto's Frame and the Radio's Case.
* The DC Power Input Wires.
+ Use a Noise Suppression Capacitor on both DC Power Leads
going to the Radio.
+ Wrap the DC Power Leads in Foil.
