CONNECTING AN
OPTIONAL ANTENNA
Your wa lkie ta lk ie c omes wi th a tele s c o ping antenna that is ideal for most applications. However, the walkie talkie’s
ANTENNA
jack makes it easy to connect
other types of antennas, too. For mobile
or base station use, you might want to
connect an optional external antenna.
Your local RadioShack store carries a
wide selection of external mobile or outdoor base-station antennas. Choose the
one that best meets your needs.
When deciding on a mobile or basestation antenna and its location, consider
the follow ing:
• The location of the antenna should
be as high as possible.
EXT
15
21-1649.fm Page 16 Thursday, August 5, 1999 11:33 AM
• The antenna and antenna cable
should be as far as possible from
sources of electrical noise (appliances, other radios, and so on).
• The antenna should be vertical for
the best perform ance.
Note: When connecting an optional antenna, always use 50-ohm coaxial cable,
such as RG-5 8 or RG-8. For lengths over
50 feet, use RG-8 low-loss dielectric coaxial cable. If th e coaxial cable’s connector
does not fit into the
EXT ANTENNA
jack,
you might also need a PL-259-to-phono
antenna plug adapter, such as Cat. No.
278-208. Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors.
Follow the installation instructions supplied with the antenna, route the antenna
cable to the TRC-236, then connect it to
the
EXT ANTENNA
jack.
Cautions:
• Do not run the cable over sharp
edges or moving parts.
• Do not run the cable next to power
cables or other CB antenna cables.
• Do not run the cable through a vehicle’s engine compartment or other
areas that produce extreme heat.
• Follow all cautions and warnings
included with the antenna.
16
21-1649.fm Page 17 Thursday, August 5, 1999 11:33 AM
Warning: When installing or removing a
base station CB antenna, use extreme
caution. If the antenna starts to fall, let it
go! It coul d contact overhead power lines.
If the antenna touches the power line,
contact with the antenna, mast, cable or
guy wires can cause electrocution and
death! Call the power compan y to r emove
the antenna. DO NOT attempt to do so
yourself.

CB OPERATI ON TIPS
The following tips will help you get the
most enjoyment from your TRC-236.
COMMON USES FOR A CB
RADIO
Business Uses
• Truck drivers and delivery personnel
can learn road and traffic conditions
and get assistance in locating destinations. A walkie t alkie is a lso good
company on those “long hauls.”
• On construction crews, a walkie
talkie qui ckly pays for itself when you
are calling for additional materials or
coordinating the activities of different work crews.
• For security officers, a walkie talkie is
more than a convenience — it is a
must for both safe ty and efficiency.
Personal Uses
• Keep in touch with home while driving to work, to the store, or to a
social activity. Let your family know
you are tied up in traffic or that you
will stop by the store on the way
home.
• If you are a two-car (or more) family,
walkie talkies are great for communicating with family members while
they are in their cars.
• Contact friends or neighbors — find
out “what’s happening” or plan a gettogether.
• Ever have car trouble or run out of
gas on the highway? What an assurance it is to be able to r adio for assistance.
22
21-1649.fm Page 23 Thursday, August 5, 1999 11:33 AM
• Camping, fishing, and other sports
are more fun with a walkie talkie.
Locate a friend or find out “what’s
cooking” back at camp.
