Connect

a

short

length

of

coaxial

cable

(RG-58

or

RG-8)

from

the

transceiver

or

exciter

to

the

coaxial

input

jack

on

the

1200-X.

A

PL-259

type

connector

is

required

at

the

amplifier

end

of

the

cable.

This

cable

should

be

as

short

as

practical

and

preferably

not

more

than

5

feet

long.
