Slept very late watching a bluray movie and woke up very late... took my sweet time before checking here. Sunday mah.
Wow... interesting and lively discussion since early morning today. Good, very good and there's one thing that most have shown here... are the machine gun bullets fired at the Monopoly, at Ass-throw, at the government and so forth but evidently most are BAD. I have been told to accept it since we are in Bolehland. Yes, can I accept it and still bark (complain) at a mountain that will always be there. Can all of you accept it and still continue to bark? I don't have to answer, as is shown by the comments by many folks here!
KU BAND AND RAIN FADE : LARGER DISH, A VIABLE BUT NOT PERFECT SOLUTIONYes, you are definitely right to point out that Ass-throw dish uses size 65 cm to be exact. I did not check the facts properly and appreciated it.
I applaud your detailed explanation of the KU band, C band and other technical mumbo jumbo. The one thing that you have shown to me is that you could be an expert in Satellite Telecommunications or at least very knowledgeable in this field. I acknowledge that. As for me, I know too little on this field and so, I wouldn't dare say that I know more than the average person. What I can say is that my knowledge has the help of everyone's good friend... the World Wide Web of "Google Search".
By the way, when you said that
common Pay TV nowadays uses 65cm dish, where did you find this out? I am confused because various dish sizes are used. You could be right. I am not sure here.

May not be correct information but have a look at this... http://www.trackdish.com/ku-band-coverage-for-india/
As I read over your reply analyzing what you are trying to point out, it seems to me (I think) that you could be moving away from the actual direction that my previous reply intended to... and that is RAIN FADE and a quick and viable solution.
Yes, you have correctly mentioned some detailed explanation of why KU band is chosen over C band for commercial TV transmission, of how higher frequency can better penetrate the weather conditions to reach our dish, of why KU band is chosen as it provides less interference because of the higher frequency. Great and informative reading. Thanks.
However, you should look at it in the perspective of the
common factor of the existing infrastructure used by
Ass-throw on the issue of "RAIN FADE" which was noted as one of the reason why the person fully terminated subscription. And that common factor is the KU Band and the 65cm Dish used by Ass-throw.
If you read carefully on my previous comments on using a larger dish, it is my intention to state an alternative solution to the Rain Fade issue eventhough it is not possible because of the "law" that do not permit home use of the large dish.
Of course,
there are other alternatives (as commented by folks here) to solve the Rain Fade issue, but many of those involve a much more arduous and hugely difficult to achieve remedies. Cable TV needs a good and solid nationwide internet cable infrastructure in place that can provide a fast and adequate speed to handle TV transmission especially HD BUT are we actually there yet? Even if cabling is ready or possible nationwide, there is also the issue of the huge capital investment to setup the Cable TV network itself. Then there is the alternative Terrestrial TV transmission using existing infrastructure that needs to be upgraded to broadcast HD and Dolby 5.1 audio but, again... are we able to do it now? I have heard for so many years of changing the Terrestrial TV broadcast from analog to digital which will release the analog spectrum for other uses. Am I right to say that TV3 will be changing over to Digital HD transmission next year? After all the years of dragged on delays, you cannot blame people for not believing it. Then again, such terrestrial transmission just cannot rival the nationwide coverage that Satellite TV enjoys.
As most (I think ALL) of you know, a very good alternative is to abolish Satellite TV monopoly enjoyed by Ass-throw. You may think why more Satellite TV broadcasters which uses the same KU band can help solve the rain fade issue... hehe... not actually solve it. When we have much more better channels with good contents at a reasonably low subscription rates then I would think many more people will be able to tolerate the "rain fade" better and many like me will be contented, keep our mouth shut when we can watch "free" Satellite channels similar to NJOI.
I wish to categorically state that I can be wrong here. After I have weighed over all the options to see which is the best and has the least time to at least address the Rain Fade issue. Its changing the 65cm Dish to a larger sized one which is of course not affordable for many people. For people who can afford it, at least a ready solution to reduce the rain fade is already available right now. Just look at the many large dish mushrooming in Bangkok, Thailand and Bandar Seri Begawan, Brunei.
Before you or anyone here immediately jump in eagerly pointing out any of my mistakes here, again I declare that I am NOT an expert here... So here are a few questions that I wish to ask you or anyone here...
1) Are there any other dish sizes besides the 65 cm used by Ass-throw such as the 75cm or 90cm type or as large as 3metres? Yes, all of us including me, know the answer to this BUT this points to my second question.
2) I don't care why KU Band is used and not C Band. I don't care about the reasons why one is preferred over the other. The question here is... can we use a much larger dish for KU Band reception?
CODE
Example of the dish sizes available... http://www.galaxy-marketing.com/complete_satellite_systems.htm
3) Is it true that KU Band reception requires just a compatible LNB (Low-Block-Noise) and Receiver/Decoder Box ?
4) Just by changing to a compatible LNB and Receiver, are we limited to only 65cm dish size for KU BAND RECEPTION?
5) Are we supposed to or can we use at least 2 LNB's on a LARGE Dish, one for KU Band and the other for C Band?
6) I think using a bigger sized Dish may NOT improve the clarity and sharpness of the KU Band reception BUT will a much larger sized Dish help in any way to address the Rain Fade Issue by improving the signal gain due to a larger parabolic dish surface-to-signal contact area?
You are absolutely right in your detailed technical explanations about KU Band and C Band and all the other explanations including the affordability of large dish.
The point is NOT one of, which and why, this or that, is preferred or used and NOT whether there are other
long term alternatives to address the "Rain Fade" issue.
I already do know about the KU Band and C Band and the various types of LNB and receivers used including the motorized Dish units... And I even know about the "ah-hem" (Dream***) Satellite Receivers which used the same Ass-throw Satellite Dish AND an internet connection to "break" (descramble) the encrypted Ass-throw signal in order to view the channels illegally (SD only). Don't know whether it works now. I do know about other things related to Satellite technology because "Google Is My Best Friend" and... yes, I repeat that I am NOT an expert.
I do acknowledge that you may know more than me and may even be an expert in the field of Satellite Techonology. However, it is totally unnecessary for you to explain it out to me those technical mumbo jumbo because my actual point is... In order to address the Rain Fade issue, there is no faster or better alternative option available other than just changing to a larger sized dish. The obstacles to using a large dish is the costly price, difficult to set and use, and the govt strict restriction of the large dish for home use. If you compare such obstacles to the other options to address the Rain Fade issue, using a large dish is at least better than the HUGE obstacles that the other option have to overcome which will undoubtedly take a long time. All it needs is our govt to stop the large dish restriction by carefully allowing selected KU Band systems (LNB, Receiver And
Much Larger Dish Sizes) which gives the least amount of interference to existing commercial telecommunications. Initially, large dish can be expensive which is beyond the reach of many but competition can bring the cost down. There are poor people in Thailand too but that doesn't stop the many large satellite dish from appearing there.
Why didn't Ass-throw use a slightly larger than 65cm dish? I don't need to answer that. Many here will answer for me. I "believe" that even a slightly larger dish size of 90cm can further help to reduce the rain fade issue. I know all the @%$@# reasons why this is not allowed. I believe/think using a slightly larger 90cm dish size or similar should be the best option to reduce rain fade because all it needs is just the govt approval and a dish cost that more people can still afford.
I could be wrong, I sensed a trickle amount of you trying to be cheesy with me when you put this question to me... quote... "Now after reading this, what do you think about Astro in terms of rain fade issue"
I loved it and do enjoy it when someone does that to me. I don't need to answer your question because I don't need to think about Ass-throw on the rain fade issue. Since many other similar Satellite Broadcasters also used the same DTH system which have the same rain fade issue, all I need to think about is, can we use a larger dish for KU band reception and what are the issues, advantages and disadvantages of using such large dish?
Ok... I end this with my question to you... Knowing that the rain fade issue will always be there, knowing that subscriptions are really overpriced, knowing that contents have an incredible amount of repeats with advertisement/commercials, knowing that there is a possibility that monopoly will continue after 2017... will you sign in or continue to subscribe to Ass-throw when you DO know that you MUST accept it because its Bolehland. Hehe... no offence yah? My apologies to you if I have. I loved a lively (maybe heated) discussions where nobody is perfect and can make mistakes.
Note : Edited to correct spelling and typo errors.Even if you use 90cm dish and above, it has signal improvements over 65cm but rain fade issue will still exist. It only mitigate a little bit, not eliminate the problem. Unless if you really got the money and space, you can use the satellite dish that Astro use in their headquarters, which the dish size is like 250cm-300cm (8-10 feet and above). Then you won't likely to experience rain fade issue anymore. But seriously, even Malaysia gov allows the people to do that, will you do it? Most people will think that it is not worth it, and it is better that you receive C band channels instead of Ku band pay TV channels. But if you receive C band and Ku band together in one big dish, then it's worth it.
You can use big dish for receiving Ku band signals, but your LNB needs to change to the High Gain LNB type if your dish size exceeds 120cm. The receiver doesn't matter, as long you use correct dish and LNB, you will be fine.
Yes you can use as many LNBs in a single dish, even for C band and Ku band, but it is pretty challenging and you need a lot of patience and time to set it up as it is harder to get adequate signal. It's up to you if you want to use C band and Ku band together.
Ku band without rain fade: 10 feet (300cm) or bigger. Or you can try consider 8 feet also. (Lol, seriously not everyone is willing to afford and use this big dish in their homes)
C band without rain fade: Recommended 6 feet (180cm). Minimum 4 feet.
*Subject to satellite output power for that particular transponder/channel.
The dish size matters between C band and Ku band is mainly because of the frequency used, as I've mentioned on my posts earlier. C band and Ku band frequency range is a huge difference.
