it

may

be

to

FM

antennas

Your

unit

approaches

the

thereotical

limit

in

FM

sen-

Sitivity.

However,

the

performance

of

your

system

is

determined

to

a

very

large

extent

upon

the

signal

condi-

tions

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

obstruc-

tions

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

installa-

tion.

If

you

live

in

or

near

an

urban

area

the

indoor

antenna

(supplied)

may

serve

adequately.

However,

if

or

if

you

live

in

a

which

is

of

it

may

be

necessary

to

Consult

with

your

dealer

or

service

man

about

the

best

method

of

selecting

and

erecting

an

outdoor

FM

anten-

na.

The

choice

of

lead-in

(feeder)

wire

is

also

important.

The

flat

ribbon-shaped

twin

lead

performs

well

elec-

trically,

is

cheaper

and

is

somewhat

easier

to

handle

in

routing

through

windows

and

around

rooms.

Coaxial

cable

is

more

expensive,

does

a

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

if

coaxial

is

selected,

make

sure

the
