Polarity 101
jimmy34741
polarity fades the other increases.Thus mantaining an average
signal.Your dish recieves both polarities the strongest of which
prevails. The odd and even channels do not have a specific polarity
they have both .There is a seperation of channels via the ird
voltage.This is where all the confusion comes from plus the fact that
multiple voltages being combined from multiple IRDs overwhelms the
signal.Each IRD sends approximately 16 volts to the LNB to enable it
to block the low noise.Hince multiple voltages have an unwelcomed
effect on not only reception but over heats the LNB plus the other
IRDs inline. Since current favors the paths of least resistance Multi
switches have been credited for disapating the excessive
voltage.However a ground at each IRD is more effective! JOE TURN

LOL, zero you said what I was thinking, but you made it short and sweet.

Wow! you're really smart!
I suppose that you already know that circular polarity microwave
transmissions are called neither vertical or horzontal, but left or
right-hand..?
Linear polarity satellites transmit with horizontal or vertical
polarization.

I guess you know that the right word here is "polorization", or do
you? The polorization types are either vertical/horizontal or left
circulat/right circular (as in DTV).

Maybe you don't, since that's not at all true.

Also untrue. Whether you're talking about polarity, or polorization
(which makes more sense here).

>they have both .
"Polarity" is actually alternating over 40 billion times a second. As
for polorization, there is only one per transponder. The odd (Tp)
channels always have one polorization, the even ones always have the
other. This is to prevent adjacent channel interferance.

What??? What happens is that the voltage selects the polorization the
LNB can handle.

Nonsense. You'd have to know very little about electricity to think
that voltages (or currents) add this way. The problem is that if the
IRDs are supplying DIFFERENT voltages, one of more IRDs could be
damaged.

About the first half of that sentence makes sense. The DC power is
supplied to an amplifier and frequency downconverter.
>Hince multiple voltages have an unwelcomed

Nonsense.

Not very likely.
> Since current favors the paths of least resistance
Actually it follows all paths, just more of it folowow the path of
least resistance. Then you start talking about voltage, which is
something different.

Nonsense, anyway there's so source of excessive voltage.

Equipment qrounding is a good idea, but WHAT are you expecting it to
do here?

it had to be a narrower coned
Lnb as it might be picking up splater off the othe two birds!! But as
usual this was most likely a marketing ploy to sell the sat-c kits!!
remember the piggyback and the #1 pin bend and the bogus readings on
the Phoenix Mode>> Well heres a new one for you remember how every one
is saying that the old splitters for RG59 want work on the sat system
because of (possible)voltage damage and or channel lost>> which after
two years of the use of this splitter I still have no problem???? Now
theres a new one cost $5.00 now because it has a diode in it!He he
he>> What about the dual lnb??He he he(The word dual allows double the
charge$$ When in actuality it is a simple splitter mounter onboard a
single LNB that cost twice as much$$$$) Think theres a diode between
the two out puts?$?$?$ Notta !! Look familiar?? A picture is worth a
thousand words!! http://www.lashen.com/vendors/jvi/hfs-x2dn.asp All
that voltage chatter is more bs .AC current is supplied to the lnb by
the IRD for RF signal amplification, a diode would prevent the RF
signal from reaching the IRD@#$%^& Same as Radiation would prevent a
living being's survival of a trip to the moon!! all smoke and mirrors
My rule of thumb is 1 LNB per satelite(not per IRD)>>So why run so
many coaxs when one would be sufficient$$$Which brings me to the
Diplexor only necessary to combine & separate antenna's impediance
from the satalite's impediance@#$%^ lots cheaper to run another coax
and omit that device altogeather!!!!!
Also ignor those left and right hand polarity sells pitches no such a
thing polarity is not in either hand it's still in the bush @#$%^&

1.The production or condition of polarity, as:
a. A process or state in which rays of light exhibit different properties in
different directions, especially the state in which all the vibration takes
place in one plane.
b. Chemistry & Physics. The partial or complete polar separation of positive
and negative electric charge in a nuclear, atomic, molecular, or chemical
system.
2. A concentration, as of groups, forces, or interests, about two
conflicting or contrasting positions.

My guess would be that it stems from a need to feel self important to

In what way does this support your nonsense?
BTW, I use some splitters of this type. Not for DSS, but for the
Xantech remote control system (which also requires DC-passing
splitters).

My reply isn't really for him, but for anyone who might believe it.
When I was in 5th grade, I knew enough about electricity to recognize
significant amounts of that as nonsense.

inductance(the path of least resistance) and E=MCsquared.Whereas M is
mass and c is time constant and E is energy then eating pie realy
makes gas and the time it takes to consume mass is directly
proporsionate to time it takes to release gas!!

I'm not sure I agree on the self importance thing. Rather, (at least for me)
I think it has to do with the constant dynamic evaluation system in our
brains as our personalities are evolving, and dynamically being formed.
We constantally "dialogue" with others to "evaluate" our personal
feelings to either reinforce what we think as right or wrong, share
rationales with others to either shift, alter, accept, or reject our
inner rationales on our thoughts and findings. Basically we define
who we are on a lot of things by engaging in dialogue with others.
As far as the over night arm-chair experts that you speak of, well,
for starters, how do you know that they are not an expert. Also,
the environment of a faceless, anonymous medium such as Usenet,
is such that all social inabitions are removed. i.e., most people
would not talk the same smack that they talk to drinking buddies
in as bar that they would in a formal professional staff meeting
at the office at work.

people like to leave some evidence of their existence. Michelangelo
painted masterpieces and created outstanding sculptures. Others have
built industrial empires, designed fabulous homes, set enduring
records in sports, or even founded great nations. Those of us with
lesser talents have to be content with raising a family, working in a
job we enjoy, and having a close circle of friends
Others who lack even these meager talents attempt to make their
impression by destruction. Some manage to do this in very spectacular
fashion, for example the attacks of 9-11; the Oklahoma City bombing,
or even those who send their countrymen out as suicide bombers.
Again, the less talented have to settle for less spectacular acts of
destruction. One particular type is the graffiti 'jerk' (no way can
it be called an artist) with the can of spray paint, leaving his mark
on walls, trees, and signs. (I'm sure an analogy could be made to a
skunk marking his territory). Since little Jimmy lacks even those
rudimentary talents, he seeks to do his destructiveness by sowing
misinformation. Alas, he isn't even good at that, so he will be
condemned to spend the rest of his days working at some cheap burger
joint, sleeping in a cardboard box, and using the computers at the
public library.
