Hi Folks,

I have installed the CB in my TJ. The 120 cm antenna came with 4.5m wire
with prewired connectors and base. I have put the antenna on the rear
bumper on the left side. The antenna cable is going under the centre
console to the middle and then under the carpet all the way back to the
end. Antenna cable is not near the bundle of cables going back for the
lights, etc. The power leads are direct to the battery. However, I have
some noise issues.

1) With the engine off, it works fine. I was briefly talking to someone
who is about 7 kms away and the sound was okay.

2) When I turn the ignition key on, there are two noises. One noise is
just a very low base kind of noise that goes away after a couple of seconds
of turning the key off. Second noise is a whining noise in the radio at
the turn of the key, which I am assuming is the fuel pump as it goes away
in a couple of seconds while the key is on.

3) When I turn the ignition key on with the antenna cable disconnected from
the radio, there is still a whining noise at the turn of the key, which I
am assuming is yet again the fuel pump, but its not as loud as when the
antenna is connected.

4) With the antenna connected, once I start the engine there is a base
noise which is independent of RPMs. There is also a whining noise that
goes up in pitch with RPM, but this whining is not extremely loud. I am
assuming this is the alternator noise. There is no ticking noise.

5) With the antenna disconnected, the whining from the alternator is
greatly reduced but there still is some base noise which does not change
with RPM.

With my limited knowledge that I have acquired so far, I think I have a
couple of issues. One is that the coax cable is providing some grounding,
thus I have a ground loop problem. Second, I am picking up noise from the
computer and alternator.

How do I deal with these issues. I know these kind of questions probably
belong in a CB related newsgroup. But I was hoping that someone with a TJ
had installed a CB radio in their rig and resolved these issues.

Thanks in advance for all the wonderful suggestions.
