    Default Iincreasing signal quality with C band LNB


    Dear Friends
    Can anyone advise which C band LNB is the powerful for weak signals. I am trying to get ARY and HUM Tv via Intelsat 10 at 68.5 E with an offset 205cm antenna (height) and 180cm (width).
    Currently i can catch the signals with 17K Nextwave LNB (60-70% signal strength, 20% signal quality), rest of the transponders are 60-70% signal strength but 50-70% signal quality)
    What if i use a 15K or 13K LNB. Will the signal quality increase for ARY and HUM Tv.
    By the way as according to lyngsat my area can cover the signal with 180-200m dish.
    Looking forward for your comments.

    Hi bassett
    I know we discussed this issue before but i am unable to get the proper signals for ARY (3864 H) and Hum TV (3774 H)......
    63-67% Signal Strength but 20% Signal Quality(stable at 20 not increasing even 1%, i can watch the channels but with lots of interfarence but sometimes pictures gets clear).....

    I tried the following operations:
    Adjusted LNB by scewing, moved the LNB in and out from the dish, inserted a conical plastic shape flask on the mouth of LNB (did not use any foil paper)......

    What is left else....i feel like the offset antenna is not suitable for C band....but what about the other transponders then.....like B4U movies and B4U Music (4064 H) they are perfect....
    63-67% Signal Strength with 65% Signal Quality The signals i am getting for these are moreover less the same as i used to get with my 3.20m prime focus dish in my previous house.

    By the way, mind you, the Vertical transponders are ok like 4124 V (Geo Tv)...signal strength is 50-60% with 45-47% signal Quality.....

    The only thing i did not try is currently i am using 17K LNB. What if i replace the LNB's with 13 or 15K....Will the problem solve.....
    Moreover you said that conical scalar ring is needed....but i can't find it here....what can be the replacement....

    By the way let me brief you about my setup...
    1- 2.00m Offset antenna ( 2.05m height, 185 cm width)
    "By the way which length should be considered as diameter?"
    2- 17K LNB Nextwave
    3- Chapparel dual band feed
    "what type of conical scalar be fit on this feed?"
    Please advise....

    There isn't a replacement, Off-set dishes require a OFF-set scaler ring, plain and simple.

    You say that some of the channels you have access to, without a problem, but you have a problem with a couple. tell us what is the FEC of the bad channels, the chances are there operating on an FEC of 7/8, and your viewable channels are on FEC 3/4. If that is the case, then the only way to fix it is get the correct scaler ring or a bigger dish. or both
    Did you e-mail the people in New Zealand , to see if they could supply you with a scalar ring..

    Large Off-set dishes are quite common in Northern Europe, Canada, and Alaska. The reason is the increased angle of the dish does not allow snow to collect and disrupt signals. Some dishes are fitted with Heaters,
    to prevent this.

    Hi friend
    The FEC for weak channels is 3/4 not 7/8. Infact almost all other channels which i get clearly are also 3/4.

    As for the scalar ring....i did contactvia mail but no one answered as yet.

    Pls comment solutions....

    Hum tv's FEC is 2/3. For ARY FEC is 3/4. I am also getting lower signal quality of around 35% for Hum Tv.

    You can get Offset Scalar ring from Chennai (Madras), India for Rs.375 with C-band LNBF. So it would be available in Mumbai around the same or even cheaper than that. If you have friends in India try to get them.

    Why Jim,,, In some parts of the world, that's all that is available, for reasons I have already discribed, and M8, a 5 meter off-set is a joy to behold.

    jim u r wrong .....we can receive any signal whether its c or ku band with any prime or offset dish ....with the same signal quality-the matter is depending upon the lnb.
