Fig. 7 -Here

we show

three European

versions

of

1939 retractable

antennas

from

Telefunken.

The

tiltable -rod (controled

from inside)

is shown

in A. the

flip

antenna

in

B,

while C and D show

a three- section

rod antenna

in its collapsed

and

fully

extended

positions,

respectively.

Jumping

on the

Wagon

Buick

and Cadillac

quickly

joined

the parade,

and

soon

came up

with

vacuum- operated

antennas

as an

option.

Aver-

age

lengths available

varied from

25" to

96 ", the latter

gener-

ally

sold in

three sections,

and

it

was

recommended

that

they

should be coated

with a thin

layer

of light

oil to extend

their

useful

life.

The most

successful

of the

new

rod antennas

were the

rotatable

aerial

mounted

above

the

windshield

and controlled

from

inside the

car by a

knob

which could

flip a

spring loaded

rod up

or down (used

by Buick

and

Ford in

1937 as

shown

in

Fig.

8), and

the side -cowl

antenna

that

was supported

on the

side cowl

by two

stanchions.

Soon,

most

of

the

car

manufacturers

were

equipping

some

or their

models

with

the

whip antenna.

In

1940, Philco

and

Zenith

supplied

Ford

with car radios

that

had the antenna

rod

coming

straight

through

the roof

and plugged

into the

top

of

the receiver,

as

in Fig.

9). By pushing

up on a plastic

sleeve,

the telescopic

rod could

be

operated

from the

front

seat.

As claimed

by a

1937 advertisement

from

Snyder.

Inc., the

rod antenna

became

available

in "every

conceivable

style"

(see the

opening of this

article).

Antennas

were mounted

on

the

fender: at

the rear

of the car,

mechanically

attached

to one

end

of the

rear bumper;

under hood

mounts;

on the

front

A

Fig. 8 -Here

is a

rotatable aerial

which

was mounted

above

the windshield

and controlled

from inside

the

car

by a

knob

which could

flip a spring

loaded

rod down

(A) or up (B).
