Dear Friends,

I have noticed that local markets are flooded with C-band LNBFs with Input Frequency range starting from 3.7GHz, which means transponders with frequencies less than 3.7GHz will not be scanned or received at all. So you will miss out many channels from those transponders.

This issue is seen more in Single Solution C-band LNBFs, commonly used by Cable Operators and MSOs.

So please note that the Input Frequency Range should be from 3.4GHz to 4.2GHz (3400MHz to 4200MHz).

Do not buy the LNBF with narrow range, even if the dealer offers it at a cheaper price.

Sample of 3.7GHz LNBF:

Normal C-band Dual Polarity LNBF:

dear friend it is for your kind information and other friends

that this single solution lnb is use mostly where, there are mobile tower signal problem.

first of all many friends donot know how to use.

the use of this lnb is as below

first you set your dish on vertical or horizental frequency

for example you set your dish on vertical frequency

and now for horizental frequency less your frequency 600 number

for examples asiasat3s b4u movies and music frequency is 3880 H 27500 3/4

but you tune 3280 instead of 3880 H 27500 3/4
symbol rate remain same.

and tune it will tune the channels.

this is the way to use single solution LNB

I am using for Aisasat3s , Insat 4a 83 degree , pak Sat 1R on 38 degree and Pas 10 on 68 degree

because here are the mobile tower create problem in signals.

thanks
 
Very Good ...........Another important Point of lnb is Noise Figure, it is Figure of the lnb is a measurement of how sensitive the lnb is or how much noise the lnb will add to the signal you may be intending to receive.always Buy Low Noise Figure Lnb that Good For Week Signal Reception.
 
this LNB is also use for two receiver when you use Splitter just like this

which donot disturb your vertical and horizental frequencies on both receivers at same time when you use both.



thanks

many thancks dear ASIF

I did That And Many Horizontal Frequancies Had work ollright now on many satalites

Insat 93E --- Insat 83E -- Apstar 76E

But Still Some Problems

I can not Tune Horizonal Frequancy Less Than 3700 -- only 3700 and more are Tuned

The HD Freq - DVBS2 - olso does not work

Finally All horizontal Frequancy on PAKSAT 38E Does not work At oll - for example ( 4020 H ) -- ( 4060 H )

I Have Tried HD recivers only ( Deam Box 7020HD ) and ( VU+ DUO ) -- I Have An old ( Truman ) Reciver but didnot Try It

I hope You and other members Can Help Me with These Problems
 
I forget To Tell you about the Tuner Configuration

I have used this cinfiguration

LO = 5150

Hi = 5750

Threshold = ??? I have tried many ( 00000 --- 5150 --- 5750 --- 6200 --- 6350 )

But still the same three Problems I told you in the prives post

are there any Diffrent Configuration for The Tuner in dreamBox Or VU+

True. Tried for d2h tp which is dvb-s2 but not worked. How can solve the problem?

Thanks.
