2.10

The

antenna

counterpoise

provides

an

artificial

earth

for

all

antennas

when used

on

ground

of

poor

conductivity

such

as

desert

or

frozen

snow

and

ice

and

should

always

be

used

with

the

ground

wave

vertical

and

end-fed

antennas.

Іп

use,

the

four

wires

are

spread

radially

around

the

RT320/1

and

the

Short

lead

is

connected

to

the

earth

terminal

of

the

RT320/1.

Тһе

counterpoise

should

always

be

used

if

doubtful

about

the

ground

conditions,

because

its

use

will

never

reduce

performance

and

will

often

improve

it.
