Hello All:

Yeah Scott is right here. In my Ford Truck I connected the Battery
Ground to the fender, then ran a braid wire to the firewall, and then to
the Hood. That made a big difference, in reducing RF Hash Noises from
the Ignition System.

Those ground straps and their connections go bad!

Jay, Mr. Faraday would be proud of you.

IIRC Ford has had that problem almost forever since the advent of the
electric in-tank fuel-pump.

I'm kind of leaning towards bad ground. Run the CB's negative to
something
well-grounded like a bolt on the frame if possible. Did that with a 2001
Ford Ranger my roommate used to have and it got rid of the noise.

I'm not convinced either vehicle mentioned (mine or my former roommate's)
ever had a good ground to start with.

Another possibility if the truck turns out to have poor grounding in
general (such as my mid-90's Kia Sportage) is go with the best ground you
can reasonably get to and use something like the Ranger RCI 2950 and run
it with ANL/NB turned on and get good at reflexively adjusting the RF
gain.

I question that assertion. I had been running a detachable-face Midland job
that had sideband and that thing was noisy as all get-go on that.

Try a .01mfd disc cap across the power leads at both ends of the Fuel pump
leads. If you got/get a copy of any ARRL handbook in your public library -
look for the section on mobile radios.

Unfortunately, the cap will do little without something to work
against. A choke would be a nice addition to this filter.

Tim,
JMO now, but sounds like u have a bad ground on your system... This will cause all sorts of AC noise in the electrical sys.. Try grounding your ant bracket, especially if its mounted on the chrome tool boxes.. It not the alluiminum thats the problem its the chrome plating.. You have to run a ground , Directly from the bracket to Ground on bed etc... Hope this was helpful... Good Dx'n

That looks like a competition mobile antenna.

As Scott said, here's the best 10/11M omni base antenna on the market
today.

Overpriced. A fool and his money are soon parted.


There is no way I want a coil at the base of my antenna. Coils choke
the current. Coils should be at the top of an antenna. Jay's antenna
has no power wasting coils in the base. On the contrary, Jay's
antenna transfers more power to the antenna then with lossy
matching methods, like a coil at the base of an antenna.

My mobile CB antenna is a Firestik KW-7. The coil is at the top.
I can talk anywhere I hear with two MRF455's. I do 120 watt peaks.
I get out just as far as I did with the 667, use less current and
don't wipe out people I can't hear with a 2 pill biased box.
