what is different c band frequences between?

Intelsat 10-02 - Thor 5/6/7 @ 1° West

3977 L DVB-S/MPEG-2 17775 3/4

ABS-3A @ 3° West

3908 V DVB-S2/16APSK MPEG-4 9582 5/6



L AND V WHAT IS THAT? :confused: ARE THEY DIFFERENT C BAND LNB?

I DID HEAR / I KNOW

L=LEFT= H = HORIZONTAL

R= RIGHT = V= VERTICAL

I DID HEAR / I KNOW

L=LEFT= H = HORIZONTAL

R= RIGHT = V= VERTICAL

C-BAND uses two types of frequences:
L LINEAR
C CIRCULAR

LINEAR frequences had two types of polarizations:
H HORIZONTAL
V VERTICAL

CIRCULAR frequences had two types of polarizations:
R RIGHT
L LEFT


so:
Intelsat 10-02 - Thor 5/6/7 @ 1° West

3977 L DVB-S/MPEG-2 17775 3/4
means:
CIRCULAR frequency with left polarization

and:

ABS-3A @ 3° West

3908 V DVB-S2/16APSK MPEG-4 9582 5/6
means:
LINEAR frequency with vertical polarization

switching from LINEAR to CIRCULAR frequency is made with a depolarzing plate
usualy is a piece of plastic :thum:

My c band lnb empty

Dont use dielectric plate plastic ?

Which can watch frequence ?
