ESTeem Models 195MHC 

ESTeem

 

offers

 

different

 

types

 

of

 

antennas

 

ranging

 

from

 

¼

 

wave

 

to

 

5/8

 

wave

 

in

 

physical

 

size.

  

The

 

user

 

choice

 

is

 

dependent

 

on

 

the

 

application.

 

 

Communications

 

in

 

the

 

VHF

 

and

 

UHF

 

bands

 

are

 

normally

 

over

 

"Line

 

of

 

Sight

 

(LOS)"

.

 

Looking

 

from

 

the

 

antenna

 

of

 

one

 

wireless

 

modem

 

you

 

must

 

be

 

able

 

to

 

see

 

the

 

antenna

 

of

 

the

 

wireless

 

modem

 

you

 

wish

 

to

 

communicate

 

with.

 

If

 

a

 

large

 

object

 

obstructs

 

the

 

line

 

of

 

sight

 

view

 

it

 

is

 

unlikely

 

that

 

satisfactory

 

communications

 

will

 

result.

 

This

 

means

 

you

 

must

 

relocate

 

the

 

antennas

 

or

 

use

 

the

 

repeating

 

freature

 

and

 

a

 

second

 

modem

 

to

 

go

 

over

 

or

 

around

 

the

 

object.

 

 

The

 

Model

 

195C,

 

195M

 

and

 

195H

 

products

 

are

 

allowed

 

by

 

the

 

FCC

 

to

 

use

 

high

 

gain

 

directional

 

antennas.

 

 

It

 

is

 

noted

 

that

 

a

 

¼

 

wave

 

antenna

 

that

 

does

 

not

 

have

 

ground

 

plane

 

radials

 

requires

 

a

 

ground

 

plane

 

to

 

operate

 

at

 

maximum

 

efficiency.

  

This

 

can

 

simply

 

be

 

a

 

conducting

 

surface

 

under

 

the

 

antenna

 

that

 

is

 

a

 

¼

 

wavelength

 

in

 

diameter.

  

For

 

the

 

Model

 

195C

 

(450

470

 

MHz)

 

this

 

is

 

approximately

 

6.5

 

inches.

  

A

 

conducting

 

surface

 

can

 

be

 

anything

 

from

 

the

 

rooftop

 

of

 

an

 

automobile

 

to

 

a

 

file

 

cabinet.

 

 

Coax

 

Cables

 

 

To

 

minimize

 

signal

 

loss,

 

the

 

overall

 

length

 

of

 

the

 

coaxial

 

cable

 

should

 

be

 

as

 

short

 

as

 

possible.

 

To

 

avoid

 

corrosion

 

select

 

coaxial

 

cable

 

manufacturers

 

with

 

tinned

 

copper

 

braid,

 

where

 

possible.

 

Listed

 

below

 

are

 

representative

losses

the

 

VHF

 

and

 

UHF

 

frequencies:

In

 

a

 

severe

 

noise

 

environment

 

it

 

may

 

be

 

desirable

 

to

 

use

 

a

 

double

 

shield

 

type

 

of

 

coax

 

cable

 

such

 

as

 

RG

214/U.

 

 

Note:

  

Pre

made

 

coax

 

cables

 

can

 

be

 

purchased

 

from

 

the

 

factory.

  

A

 ‐

3

 

dB

 

loss

 

means

 

you

 

have

 

lost

 

1/2

 

of

 

your

 

signal.

  

A

 

+3

 

dB

 

gain

 

means

 

you

 

have

 

doubled

 

(x2)

 

your

 

signal.

 

 
 

 

Keep

 

the

 

antenna

 

feedline

 

as

 

short

 

as

 

possible

 

to

 

minimize

 

losses.

 

 
 

 

Extreme

 

care

 

must

 

be

 

taken

 

when

 

attaching

 

coax

 

connectors

 

to

 

the

 

antenna

 

feedlines.

  

If

 

there

 

is

 

any

 

error

 

in

 

making

 

this

 

connection

 

the

 

output

 

of

 

the

 

transmitter

 

will

 

be

 

greatly

 

reduced.
