    Default Transform a 10 ft mesh dish into solid


    I need to do it because i can not receive many transponders on C-band and nothing viewable on Ku-band.
    Have someone already try this or can give some tips?
    I want to try to paint it with a mixture of cement (those used to repair crashed car) and paint to fill in the holes. Should it be ok?
    Sorry for bad english.

    ANY flat paint should do, avoid too much glossy, reflective paint as it will damage your lnb cap in the long run. avoid mixing it with cement or something similar that may alter the curvature of the dish. i suggest you lay down some thin foil over the dish to close the mesh then paint it over. however, it all depends on how you lay down the foil, lol. try to avoid wrinkles on the structure too. some suggest paint containing titanium dioxide (most paints do) or graphite paint. good luck.

    Thanks boknoy,
    I have already done this but maybe the paint i used were too fluid and the holes were note filled in. I think I will do a second try as your advices. Do you think it will improve a lot my reception if done correctly?

    Just a precision. I painted the dish with black paint. Does the colour have any effect on the reception quality?

    congratulations. i don't think color has anything to do with the reception quality.

    it will effect on high frequency like Ku band 12 GHz.. and so..
    the mesh dish good for receiving Ku signal need to be smaller than 2mm mesh. Solid dish have i think at least 5% to 10% gain to mesh dish.

    To make a comparison, with the same configuration, I have 64% quality level on Parabole Reunion using a 70 cm solid dish, only 54% with the 10 ft mesh dish. However, with the 10 ft, the Ku-band lnb is off by 6 cm from the focal point because it is placed near the C-band lnb which is iguess centered.
    On C-band, i can see most of the transponder only on very clear day.

    could be that you are simply way out of footprint to get a clear reception.

    a solid dish won't affect that much, almost negligible especially if the perforations on the mesh (the "holes") are kind of narrow enough not to let the ku band signals pass through. i believe the mesh dish was in concept for windloading problems with early actuators/motors but nowadays, even 2.5 solid dish can easily be handled by the newer motors so mesh dish are slowly dying a slow death, i think. windloading for both dishes are almost the same at 80kph. but if you belong to out of footprint side lobe signals, then a solid dish is much preferable to get that extra 5%-10% signal gain as most mesh dish have a tendency for poor side lobe signal rejection. also take into consideration that most mesh dish will easily bend and deform.

    There are a couple of ways of converting a mesh dish to solid... but really none of them will give you , the same result as a genuine solid dish, be it a spun alum solid or a panelled dish.

    The first way is to retain the mesh and use fibreclass mat over the mesh and spray it with fibre glass.

    The 2nd, is to remove the mesh panels and replace with sheet metel, panels the size of each segment , with a 1 inch strip down one side to overlap the next segment.
    I know of someone that did this with a five meter dish, and really the performace was reduced to a 3.7 meter dish.. hardly what you would call a success, and really for a reletivly small dish like a 10 footer, it's hardly worth the work.
    Some large dishes 7 meters and over, have a solid centre section, with the outside meter ring of the dish mesh, this to allow for Ku reception, and to cut down on the weight factor.

    Thanks for all contributions to this thread. A little precision, my dish is a 12 ft one, not 10 ft.
    I prefer the painting solution because it does not need to remove the dish, replace the panel and redo the pointing job (very hard work for me).
    I spent 4 kg of black paint now and only 1/5 of the dish is now totally covered . It is very ugly but I have 10% more quality signal in Ku-band, not good enough to view more channels.
    I plan to use brown and green paints to do the rest so it would look like an army dish in the jungle.
    Regards.
