A Real

Charmer. No,

the Cobra V isn't some

kind of late model

snake, it's

a glitzy new

CB

rig

which just

blew

on the scene from the windy

city.

The

Cobra

is

right in step with

the latest trends

in CB gear -little

in size,

all transistorized, low

cost, efficient; and

it claims to be the

first rig on

the market with

a "special protective

circuit

for

transmitter

components."

In the

performance department,

the

Cobra

V

has transistorized

transmit

/receive

switching

(that means

no moving parts and

therefore less

chance for

mechanical failure when

a tired

old

relay

drops dead

of

fatigue).

There's also

a clever

new

voltage

filter to improve

the

clarity of the

signals inhaled

by the

Cobra V.

B &K Cobra V

CB

Transceiver

Running a

whopping

100% modulated

5 -watt

input

on any

five

channels, the set puts up quite

a

showy front

with

a

walnut

grain

finish ('neath

that

frilly

walnut

finish

is an all steel

housing).

For those

wise

guys out there in the reading

audience

who come

on strong

with

the

fancy

12

a

what's

new

product

column

that's

fun

to

read

tech talk,

we

note that the Cobra V comes on

strong with better

than

half

a

microvolt

sensi-

tivity (for 10 db S /N) and

a

selectivity

of

6 db

-O.K.?

You can

get

enough literature on the Cobra

V

to

stuff a megacycle if you drop

a card or

letter

to the manufacturer, B

A'

Matchless Antenna? We've

seen some

wild

looking things

connected to the output of CB

rigs but the Antenna

Specialists

MACH

III makes

the rest

of

them

look like as tame

as a tranquilized

bunny rabbit.

Not

knowing

exactly

how

to

describe

it, the best

we

can do is

simply

parrot

the description of

the thing as

stated

by the

manufacturer: "A spiral shaped,

printed- circuit

coil,

waterproofed

and

shock -suspended

inside a

wing- shaped

ornamental base."

This

all

boils

down

to

the fact

that this circuitry is a "involute

transducer"

(wha

?).

Now that the engineering is clear to you (be-

cause

it

certainly

isn't

to

us) we

can

get into the

performance

of

the

little

devil.

It's

a

32 inch

steel

whip, basically, set into

a futuristic cyco -lac

plastic base

containing all of

the sophisticated

jazz

we just told you about (don't ask us to re-

peat it please).

Available in a

variety

of

mounting types (with

or

without

shock

spring),

the MACH III is

DC

grounded for optimum SWR across the band.

The

antenna

may be peaked up to your particu-

lar rig by means of an adjustment in the base.

Prices (depending

on

mounting hardware)

range from

$12

to

$25.

who

figured

this

one out are at Antenna Specialists,
