AM

outdoor

antenna

In

steel

buildings

or

at

a

great

distance

from

the

transmitter,

it

may

be

necessary

to

install

an

outside

long

wire

antenna.

The

end

of

this

should

be

stripped

of

insulation

and

connected

to

the

At

this

keep

the

connected.

FM

antennas

Your

unit

approaches

the

theoretical

limit

in

FM

sensitivity.

However,

the

performance

of

your

system

is

determined

to

a

very

large

extent

upon

the

signal

conditions

where

the

antenna

is

placed.

The

reason

is

that

FM

broadcast

signals

travel

in

straight

paths.

Therefore

they

can

be

blocked

by

natural

Or

man-made

obstructions

such

as

mountains,

hills,

or

buildings.

At

large

distances

from

the

transmitter

the

curvature

of

the

earth

acts

as

a

screen

between

transmitter

and

receiver.

Consider

the

signal

conditions

in

planning

your

installation.

If

you

live

in

or

near

an

urban

area

the

indoor

antenna

(supplied)

may

serve

your

needs

adequately.

However,

if

desired

stations

are

weak

due

to

natural

obstructions,

or

if

you

live

in

a

building

which

is

made

of

steelreinforced

concrete

(which

acts

as

a

shield)

it

may

be

necessary

to

install

a

good

outdoor

antenna.

FM

outdoor

antenna

Consult

with

your

dealer

or

service

man

about

the

best

method

of

selecting

and

eracting

an

outdoor

FM

antenna.

The

choice

of

lead-in

(feeder)

wire

is

also

important.

The

flat

ribbon-shapped

twin

lead

performs

well

electrically,

is

cheaper

and

is

somewhat

easier

to

handle

routing

through

windows

and

around

rooms.

Coaxial

cable

is

more

expen-

sive,

doesa

much

better

job

of

minimizing

interference,

is

less

prone

to

the

effects

of

weather

and

close-by

metal

objects,

and

is

nearly

as

good

a

signal

conductor

as

the

ribbon

type

wire.

The

latter

is

particularly

true

of

foam-type

coaxial

cables.

Coaxial

cable

is

somewhat

more

difficult

to

install

at

the

point

where

the

cable

enters

the

building.

If

coaxial

cable

is

selected,

make

sure

the

antenna

is

de-

signed

to

drive

that

type

of

cable.
