1 CBand dish , 2 Stb, What to Do

afzal_q

Hello ,
I am in need of Urgent Help , I have a 6 ft Cband Dish (Universal Brand) Connected to my Melbon

Stb , i Am using it to recieve peacetv in my room ,now my brother also want to watch it in his

room , can you tell me what is needed to done with my current setup , i want both the connection

to operate independently, i am ready to purchase another melbon stb (at is Cheap Cost only 1000

Rs) , also now i have dual polarity single output lnbf ,so does using a dual output lnbf will

solve my problem ,or my channels will be splitted as when i asked a engineer who did this setup

for me told me channels will be splitted if you use dual output lnbf , i need your suggestion as

what can be done to solve my problem

also i have 2 Tatasky lnb one with one output and other with 3 output , can I use it place next

to my current cband lnbf and connect it to my melbon Stb , does it will work


also , it is difficult to find a Dual output Cband Lnbf in mumbai (india) , but i think single

output lnbf is easier to find , so if i buy 1 single output lnbf and place it next to my current

cband lnbf , will this works


, pleaaase help me i would be really thanksful to your Guys


Ps:my Only Purpose of Buying a Cband dish is to watch peacetv , i dont care Whether I get Other

Channels or not , but peactv is needed

Welcome to the forum afzal_q

Yes your only solution is to replace the single output with a twin or dual output and purchase a second lemon stb.....

Don't know what your 'engineer' is talking about as my understanding is that with a dual polarity twin output lnbf, two output cables and two stb's they should both work independently of each other.

wow Guys, this Forums Rocks, i just posted my Question and Even got a Reply , thanks Freind , for your replies , actually my engineer said you will be needed a new dish , new cable and a news stb , if you want second connection , he say if try to take signal from first dish then channel will be splitted , i want to ask can it really happen

Topper

No you cannot use a splitter as you will then have two stb's trying to control the polarity of one lnbf, it will only end in tears.

You did not say what kind of engineer he was.........., this is similar to the type that you need

Hello , I Just a Visited a Shop Today Looking for Cband Dual Output Lnb , First He ask what Are you needing it for , i told him about the my problem and told that i want to watch Peactv , Qtv and other Channels , he told that Cband Dual output Lnb Will split Your Channel , one outputs you Will get peactv and on other Output you will Get Q - tv , I want to Ask is these really Can happen, As Dual output lnb Can Really divide the Horizontal and Vertical Frequency to Different Outputs ,


He Suggest me this

If you want to Watch only Peactv only then use powerdivider
If you want to Watch to Peactv along with Qtv and other channel then Use Dual output Lnb With power Divider

Here are the cost what he told me are they correct

Lnb- 400
Feedhorn -250
POWER DIVIDER - 550
Labour charges -550

please help me

Everybody i talk to says Channel will get splitted , can you tell me why do Channels get Splitted?,when do these happens , just want to know

I don't know anything about C-band LNBs but is it that the dual port LNBs you are looking at have one port for vertical and one for horizontal? If so this is your problem. You need an LNB with both polarizations available on each port. (A bit like the difference between quad and quattro.)

Analoguesat

LNB's are active devices not passive devices (they reconfigure internally depending on the switching signals sent from the set to boxes)

Therefore you can have at least 2 states (or 4 for Ku band!) whereby a combination of voltages or electronic tones alters the parameters of the lnb.

Therefore each box requires an independant feed from the lnb if its to work properly. If you just split one cable then the boxes will be working against each other when two different channels are accessed.

can you tell me how to install the power divider , does it needed to install the at a specific point , i mean in the beginning or at the end ,

it is simple like these

i will connect the output from the satellite lnb to IN port of Power Divider
then i will connect Two output to Two Stbs,


is this all needed to done or anything more , also how can i determine which is master port of Power divider , i think master port connected stb decides what to see ?

Analoguesat

Forget the power divider and do it properly with a dual output lnb!

Hey Afzal,
Please tell me where to get power divider in Mumbai. I tried a number of shops in Lamington road but could not find it.
Also somebody please tell me if power divider works with Ku band LNB.

Thanks

Analoguesat

We have spent the last 2 days telling him why a power divider wont work, and the same reasons apply to Ku band.

Just buy a cheap dual or quad output lnb and stick it onto the dish. Far far simpler

Sorry Admin , if am Annoying , it is just that i m bit worried because i want to do this for my uncle , and dont want to mess anything ,




as for Suggestion given by the admins does this same Applies if i want to connect 3 tv to my single Cband dish , does using a 4-output lnb will work ? ,

narendralv

Dear Analoguesat,
I know what exactly I want and I asked for the same. Thanks for your advice anyways.

Ok , now what do you think of using a Dual Output Lnb , With It ,Will I able to Recieve all channels on Both the Output , and What about using an Stb with Output function, so that i will connect the output from this Stb to Another Stb , what are the Limitation to this Setup ,

Yes you will

and What about using an Stb with Output function, so that i will connect the output from this Stb to Another Stb , what are the Limitation to this Setup ,[/QUOTE]

You can only use one receiver at a time - same problem as the power divider.

You can do this but, when both STBs are on at the same time polarisation control signals come from STB 1 which means STB 2 can only view transponders that are the same polarisation as the ones being currently viewed on STB1. If STB 1 is switched off STB 2 then gains control over polarisation.
