AN TEN N A REQUIREM ENT
This transceiver w ill operate with any standard 52 ohm ground-plane, vertical, mobile whip, long wire
or other CB antenna. A standard SO-239 type connector is provided on the back panel for use with
popular PL-259 antenna plug.
AN TEN N A IN S T A L L A T IO N
When the TS-340 DX is used as a base station, any Citizens Band beam, dipole, ground-plane or
vertical antenna may be used. A ground-plane type w ill provide greater coverage, and since it is
essentially non-directional, it is ideal in base station to mobile operation. From base station to base
station, or point to point operation, a directional beam w ill give greater distance even under the
adverse conditions.
M O B ILE AN TEN N AS
A vertical whip antenna is best suited fo r mobile use. A non-directional antenna must be used for
best results in any case. The base loaded whip antenna w ill normally provide effective
communication. For greater range and more reliable operation, a fü ll quarter wave-whip may be used.
Either of these antennas use the metal car body as a ground plane, and the shield of the base lead as
well as the metal case of the transceiver should be grounded. A standard antenna connector (type
SO-239) is provided on the transceiver fo r easy connection to a standard PL-259 cable termination.
M O BILE IN S T A L L A T IO N
A location in the car or truck should be chosen carefully fo r convenience of operation and
non-interference with normal driving functions. Mounting may be under the dash or instrument panel
or any place a secure installation can be made. An easy-release mounting bracket is supplied and
additional perforated straps or brackets may be used as desired. The 12 V o lt cable may be connected
to any conven ent terminal, but preferably to the ignition switch to prevent unauthorized persons
from operation of your unit. With this method, the unit w ill only operate when your key is turned
on. Engine ignition interférence should not be a problem, and vehicles equipped w ith standard
broadcast radios should hâve enough suppression to eliminate ignition interférence. If interférence is
present, any skilled auto radio repairman should be able to eliminate it fo r you.
BASE S T A T IO N O PERATION
For base station use, a suitable regulated 2.5 AMP power supply is recommended. When a power
supply is used, simply connect the red (+) and black (— ) terminais on the power supply o f the (+)
and (— ) leads on your TS 340 DX
