    Default Need help getting KU band on Intelsat 19- WEWAK Papua New Guinea

    HI all and thank you in advance. I also apologize if this has already been dealt with elsewhere here and I may have missed it and or if this not the proper place to ask this here again.
    1. Why is that I am unable to even get KU Band signal from my location here in PNG?
    2. I am able to get C-Band channels without any problems here and why can’t it be the same for KU bands.
    My specs:
    Location: I live in WEWAK, north of Port Moresby in Papua New Guinea. Approx Coordinates: 3.5°S 143.7°E
    My set up.
    1 x C-Band (prime focus) 1.8m dish FTA strong satellite MPEG2/DVB S2 Works find on all FTA/Paid Channels
    1x 1m KU band offset dish Uni Ku band LNB LO 9.75/10.60 GHz, same FTA strong receiver
    I have a sat finder meter analogue that works perfect for me.
    Note: Using the same setup on KU band, I have been able to receive FTAs from other Sats esp JCSAT4B without problems.
    Why it doesn’t seem to be the case for Intelsat 19.
    I’ll wait for any tips, info or help.

    Are you saying you can receive C-Band from IS19 OK?

    Do you get Ku signal readings from IS19 on your sat meter?

    JCSAT4B and IS19 are almost completely opposite pointing directions from your location, so it's not a fair comparison.

    Perhaps your Ku signal path to IS19 is obstructed... does your Ku dish have a perfectly clear view to IS19?

    According to the IS19 footprints on Satbeams, your area is only covered by the SW Pacific beam.

    Which IS19 transponder/s are you trying to receive?

    based on this footprint your 1 Meter is too small

    Which is why I asked which transponders he's trying to receive.

    If it's the Aust/NZ beam, his location is not covered.

    A much larger Ku solid dish of say 3-4m may be sufficient.

    Satbeams show a SW Pacific beam for IS19 which covers PNG, but Lyngsat don't list any IS19 transponders with a SW Pacific Beam.

    I'm guessing the OP is after Aust/NZ and his 1m Ku dish just won't cut it.

    Thank you Administrator mtv and senior member apsattv.
    Firstly, let me say sorry double posting this same thread in different areas which is against the rules of this forum. It won’t happen again.

    (1) I am able to receive C-Band from IS19 with no problems. All FTA channels ok
    (2) NOT able to pick up KU signal reading from IS19 with the sat meter.
    (3) Dish has pretty clear view to IS19
    (4) I am trying to receive 12286H, 12526H, 12529V, 12613H and 12726H which I think are FTA from IS19
    (5) I know JCSAT4B is in the opposite direction, I wanted to be sure my setup was working (dish, KU band skew etc.) so I pointed there and pick up strong signals which carries TV wan. PNG’s Digicel Paid TV channels there. This proves my setup is ok.

    Back to KU on IS19 and from your replies, I gather that (1) from my footprint my 1M dish is too small and (2) My area is covered by SW pacific beam which does not have anything on unlike the Aust/NZ beam. (Will have to do more reading on Lyngsat and SATbeam sites)

    My solutions for now (1) remove my C-Band LNB from 1.8M prime focus dish and find for an adaptor/LNB holder to fit my KU band univ LNB on it and try again.

    (2) Look for a new larger Dish over 2M to try again.

    Thank you.

    you may be able to find locally a older 3mtr mesh previously used on c band they work ok on ku as well but you have to be half a mtr larger than recommended by sat beams ie 1.0 becomes 1.5 mtr etc

    Default KU band on larger mesh dish?

    Hi thank you for that tip.
    Am looking around now for an older mesh dish as you mentioned.
    I didnt know it could pick up KU band signal also

    Not quite correct.

    The mesh must be rated for Ku band.

    Not all C-band mesh is suitable.

    Just one question here
    Will the focal distance for the KU band be the same as that of C-Band LNB on the larger dish?

    Remember that as you go UP the frequency band, the signal becomes more difficult to receive so you need a bigger dish and of course, the signal must be directed at you a bit like a spot light beam.
    Over the years due to technology, Satellite beams are better directed to their target audience which doesnt help anybody not in the smaller footprint today.
    Solid dishes are preferred for Ku Band but making them bigger poses other problems such as needing substantial foundations to cope with their bigger wind loading area so using Mesh for the reflector reduces that but as posted, it must be spaced to collect and reflect the Ku band signal and not let it pass uselessly through.
    I stand unequivicably behind everything I say , I just dont ever remember saying it !!

    I couldn't see a 12529V transponder listed on Lyngsat.


    If you meant 12569V (Channel 9) no hope, as the signal is weak even in Australia and is multistream 16APSK which your box will not decode.
    Those signals are not intended for direct-to-home reception. Some people have had success with large dishes and a compatible decoder, but it would be extremely unlikely to receive in your area.
    Would be very interesting if you could manage it though.
    Lyngsat says 12613H is NW Pacific Beam. Note that only some channels are FTA on those transponders, others are encrypted.

    If you plan to try your prime focus dish for Ku Band, you will also need a prime focus Ku Band LNB.

    Keep us informed on your progress.

    If you mean your existing C-Band dish, yes, but you will need a prime-focus Ku-Band LNB.

    John Coutts... based in Lae, can advise you on the right setup. I know he gets all the ku band channels you refer to.

    Lae is somewhat closer to the Aus/NZ beam than the OP.

    Is John also receiving all the Channel 9 multistream 16APSK signals?

    What gear is he using?

    Yes
    Lae is within the path while Wewak is outside of the beam so its possible he's receiving it from 3-4M large Dish.

    There is no magic brickwall that stops the signal outside of published footprints. In many cases the publically available footprints you find on the web are not that accurate and are on the conservative side. The t.p you mention are all received in Indonesia on 1.8M and upwards sized dishes.

    My estimate for your location is eirp around 40.

    Your 1.8M should manage to load 12726 H which is usually the strongest t.p

    One thing you need to be aware of is the LNBF skew which can be tricky to get right

    Yes apsattv
    thank you...
    I'll be mounting a KU band on my 1.8 dish after removing the c-band one as soon as I get a bracket for it.
    I'm thinking the skew could be at 5 or 6 o'clock position.
    Will update on the progress after I try this out...
    Thank you
