*Note:

 

It’s

 

advisable

 

to

 

have

 

someone

 

watching

 

the

 

feed

 

while

 

it’s

 

being

 

driven

 

as

 

if

 

the

 

pot

 

isn’t

 

correctly

 

calibrated

 

there

 

is

 

the

 

possibility

 

to

 

damage

 

the

 

assembly

 

if

 

the

 

LNB

 

hits

 

the

 

pol

 

motor

 

or

 

the

 

reflector

 

harness

 

is

 

coiled

 

around

 

the

 

feed.

   

 

7.

 

Observe

 

the

 

physical

 

alignment

 

of

 

the

 

feed:

 

The

 

RX

 

waveguide

 

should

 

be

 

facing

 

downwards

 

with

 

the

 

TX

 

reject

 

filter

 

to

 

the

 

right,

 

vertically

 

with

 

the

 

LNB

 

horizontally

 

above

 

the

 

assembly

 

with

 

the

 

coax

 

exiting

 

to

 

the

 

left.

 

Later

 

revisions

 

of

 

this

 

system

 

use

 

an

 

additional

 

length

 

of

 

waveguide

 

with

 

the

 

filter

 

above

 

the

 

assembly

 

horizontally,

 

and

 

the

 

LNB

 

facing

 

downwards

 

on

 

the

 

left

 

side

 

(as

 

shown

 

on

 

the
