RadioShack PRO-84 Scanner Radio - 200 Channels
http://www.radioshack.com/product/in...ductId=2180625
This is a Small Handheld Scanner with a relatively short
Antenna connected to the Radio via a BNC Connector.

MOST LIKELY - When the Scanner's Backlight is used :
The Scanner uses more Power; and this Reduces the RF
Gain of the Scanner; resulting in Less RF Signal being
heard along; with more internal Noise from the Radio.

Usually the simple Answer is a Bigger Antenna.

RadioShack Pro-84 Scanner Help :
Many Scanner Radio Problems can be "Fixed"
with a Better Scanner Antenna

Here are some Scanner Antenna 'Options' :

1 - For Mobility try a "Telescopic Handheld Scanner Antenna"

Thank you for your help. The thing is that I have a large old CB
antenna(has 2 large pieces of copper wire extenting a few feet in
opposite directions). I sometimes have it connected to and for some
reason the interference happens more often with that antenna than when
I use the small antenna that came with the unit. Also the
interference tends to go away when I turn the backlight on when using
the old CB antenna. LOL maybe my scanner is just cursed.

W2T,

The large old CB Antenna just may be 'too big' for this
small Handheld Scanner.

-IF- Your primary Interest is in the hearing the CB Band :
Then Buy a CB Radio and use a CB Antenna to do so.

Citizens' Band (CB) Radio Band -Info-
http://en.wikipedia.org/wiki/Citizens'_band_radio

A simple Snake Antenna for the CB Band for Scanners
made from a single piece of Coax Cableshould work with
out overloading the Scanner.

First buy a 20~25 Foot long piece of Coax Cable
with BNC Connectors on both ends.

CB Band {Amateur} Vertical Antenna Calculator
http://www.csgnetwork.com/antennaevcalc.html

Snake Antenna - Antenna Construction Steps :
* Measure-out from one of the Ends of the Coax Cable
19 Feet 6 Inches and 'cut' the Coax into two pieces.
* Take the 19 Feet 6 Inch piece of Coax Cable and then
Measure-out form the BNC Connector End 8 Feet 8.25 Inches
and carefully 'cut' around the Outer-Cover of the Coax,
being careful not to cut into the Inner Insulator.
* On the BNC Connector side of this 8 Feet 8.25 Inches
'cut' {very near to the 'cut'} place a Clamp-On Ferrite Bead
and place a Plastic Wire Tie on the Coax on each side of it
to hold-it-in-place.
* Make a Long 'cut' down the remain section of the Coax
away from the BNC Connector.
* Remove the Outer-Cover of the Coax from this section.
* Carefully 'snip' the Individual Wires of the Coax Shield
at the 8 Feet 8.25 Inches 'cut'.
* Remove the Coax Shield from this Section.
* Fold-over 1.5 Inches of the End-Tip of the Inner Insulation
back on to itself froming an Eye-Loop. Secure with Three
Plastic Wire Ties leaving a Half-Inch Eye-Loop for Rigging.
* Attach a Nylon-Poly Rigging Rope to the Eye-Loop.

You now have built your own End-Fed "Snake" Dipole Antenna
for the CB Bands to use with your Scanner.

NOTE - If you started out with a 25 Foot piece of Coax with
BNC connectors on both Ends : You have a 5 Foot 6 Inch
piece of Coax left over to make a shorter A2L Antenna
to use with your Scanner.
Note - A2L = Almost-A-Loop -because- it is not electrically
connected as a Loop -but- is shaped like a Loop -hence-
'Almost' A Loop.

A2L Antenna - Antenna Construction Steps :
* Measure-out from the BNC Connector of the Coax Cable
Two Feet (2') and carefully 'cut' around the Outer-Cover of
the Coax, being careful not to cut into the Inner Insulator.
* On the BNC Connector side of this 2 Foot 'cut' {very near to
the 'cut'} place a Clamp-On Ferrite Bead and place a Plastic
Wire Tie on the Coax on each side of it to hold-it-in-place.
* Make a Long 'cut' down the remain section of the Coax
away from the BNC Connector.
* Remove the Outer-Cover of the Coax from this section.
* Carefully 'snip' the Individual Wires of the Coax Shield
at the 2 Feet 'cut'.
* Remove the Coax Shield from this Section.
* Take the Inner Insulation and from a Single-Turn Loop
with it with 4 Inches overlapping to create a One-Foot
Diameter A2L Loop. Secure this Overlap with three
Plastic Wire Ties evenly spaced.
* Bend the Loop and Coax so that the Coax extends down
from the Loop. {Looks like an outline of a Lolliipop}
http://www.resene.co.nz/kids/stencil...lollipop_l.jpg

Place the A2L Antenna Element next to a Window; on a
Desk-Top; hang it on a Wall; or Wear-It while walking around.

FWIW - This One-Foot Diameter A2L Loop Antenna picks-up
the 800~900 MHz Frequencies fairly well.

- Thank you for your help. *The thing is that I have a large old
- CB antenna (has 2 large pieces of copper wire extenting a
- few feet in opposite directions). I sometimes have it connected
- to and for some reason the interference happens more often
- with that antenna than when I use the small antenna that came
- with the unit. *Also the interference tends to go away when
- I turn the backlight on when using the old CB antenna.
- LOL maybe my scanner is just cursed.

W2T,

The large old CB Antenna just may be 'too big' for this
small Handheld Scanner.

-IF- Your primary Interest is in the hearing the CB Band :
Then Buy a CB Radio and use a CB Antenna to do so.

Citizens' Band (CB) Radio Band -Info-http://en.wikipedia.org/wiki/Citizens'_band_radio

A simple Snake Antenna for the CB Band for Scanners
made from a single piece of Coax Cableshould work with
out overloading the Scanner.

First buy a 20~25 Foot long piece of Coax Cable
with BNC Connectors on both ends.

CB Band {Amateur} Vertical Antenna Calculatorhttp://www.csgnetwork.com/antennaevcalc.html

Snake Antenna - Antenna Construction Steps :
* Measure-out from one of the Ends of the Coax Cable
19 Feet 6 Inches and 'cut' the Coax into two pieces.
* Take the 19 Feet 6 Inch piece of Coax Cable and then
Measure-out form the BNC Connector End 8 Feet 8.25 Inches
and carefully 'cut' around the Outer-Cover of the Coax,
being careful not to cut into the Inner Insulator.
* On the BNC Connector side of this 8 Feet 8.25 Inches
'cut' {very near to the 'cut'} place a Clamp-On Ferrite Bead
and place a Plastic Wire Tie on the Coax on each side of it
to hold-it-in-place.
* Make a Long 'cut' down the remain section of the Coax
away from the BNC Connector.
* Remove the Outer-Cover of the Coax from this section.
* Carefully 'snip' the Individual Wires of the Coax Shield
at the 8 Feet 8.25 Inches 'cut'.
* Remove the Coax Shield from this Section.
* Fold-over 1.5 Inches of the End-Tip of the Inner Insulation
back on to itself froming an Eye-Loop. *Secure with Three
Plastic Wire Ties leaving a Half-Inch Eye-Loop for Rigging.
* Attach a Nylon-Poly Rigging Rope *to the Eye-Loop.

You now have built your own End-Fed "Snake" Dipole Antenna
for the CB Bands to use with your Scanner.

NOTE - If you started out with a 25 Foot piece of Coax with
BNC connectors on both Ends : You have a 5 Foot 6 Inch
piece of Coax left over to make a shorter A2L Antenna
to use with your Scanner.
Note - A2L = Almost-A-Loop -because- it is not electrically
connected as a Loop -but- is shaped like a Loop -hence-
'Almost' A Loop.

A2L Antenna - Antenna Construction Steps :
* Measure-out from the BNC Connector of the Coax Cable
Two Feet (2') and carefully 'cut' around the Outer-Cover of
the Coax, being careful not to cut into the Inner Insulator.
* On the BNC Connector side of this 2 Foot 'cut' {very near to
the 'cut'} place a Clamp-On Ferrite Bead and place a Plastic
Wire Tie on the Coax on each side of it to hold-it-in-place.
* Make a Long 'cut' down the remain section of the Coax
away from the BNC Connector.
* Remove the Outer-Cover of the Coax from this section.
* Carefully 'snip' the Individual Wires of the Coax Shield
at the 2 Feet 'cut'.
* Remove the Coax Shield from this Section.
* Take the Inner Insulation and from a Single-Turn Loop
with it with 4 Inches overlapping to create a One-Foot
Diameter A2L Loop. *Secure this Overlap with three
Plastic Wire Ties evenly spaced.
* Bend the Loop and Coax so that the Coax extends down
from the Loop. {Looks like an outline of a Lolliipop}http://www.resene.co.nz/kids/stencil...lollipop_l.jpg

Place the A2L Antenna Element next to a Window; on a
Desk-Top; hang it on a Wall; or Wear-It while walking around.

FWIW - This One-Foot Diameter A2L Loop Antenna picks-up
the 800~900 MHz Frequencies fairly well.

Here is another simple CB Radio Antenna to use with a Scanner
-or- for that matter a CB Radio or any other Radio used primarily
to Monitor the CB Radio Band. Works for 10 Meters too.

Workman BS-1 Dipole Antenna -cut- for the CB Radio Band.
Frequency Coverage : 26.065 MHz to 27.085 MHz

This is a basic Dipole Antenna with 9-Feet per side comes with
a Center Connector and Coax Cable feed-in-line. Can be used
Indoors in a Corner of a Room with the Arms along two Adjacent
Walls or Outside under the Eaves of the House.

INDOOR Base ANTENNA for CB Radio - Wire Dipole - New
http://cgi.ebay.com/_W0QQitemZ160194837706

The Coax Cable has PL-259 Plugs on the Ends so a
SO-239 Jack to BNC Jack type of Adapter is required.

Usually the simple Answer is a Bigger Antenna.


Got a soldierless BNC Connector from Rat Shack;

hooked 5 feet of wire to it

put a small suction cup on the window &

Hooked it all up..

cost : $ 5:00

Great reception.. !
