jimmym40 Posted August 16, 2007 Share Posted August 16, 2007 Can someone explain this to me. I thought satellite engineering was far advanced to let the rain interfere. What about the military satellites, do they get blacked out - no way. I know, this is Thailand, but still? Link to comment Share on other sites More sharing options...
Florin Posted August 16, 2007 Share Posted August 16, 2007 The short answer is that the dish they provide is far too small for what it's supposed to do...also, I'm sure they chose the cheapest grade materials possible. Link to comment Share on other sites More sharing options...

I thought satellite engineering was far advanced to let the rain interfere.What about the military satellites, do they get blacked out - no way. I know, this is Thailand, but still? There are two bands mainly for satellites. one is KU and one is C. KU bands cannot go through the clouds well. And that is what UBC satellite uses. C bands on the other hand are alright even with the dark big clouds. am sure you would get better answers to what you are looking for by some other posters. i just know basics Link to comment Share on other sites More sharing options...
Sanpatong Posted August 16, 2007 Share Posted August 16, 2007 am sure you would get better answers to what you are looking for by some other posters Too much honour... I'm blushing at my keyboard. Here it goes: UBC dishes are made from recycled coke can lids in the very same workshops where they make baht-bus coverings. That's why you see people collect can lids so industriously. Two mysteries solved for the price of one. Link to comment Share on other sites More sharing options...
Wash Posted August 16, 2007 Share Posted August 16, 2007 (edited) Can someone explain this to me. I thought satellite engineering was far advanced to let the rain interfere.What about the military satellites, do they get blacked out - no way. I know, this is Thailand, but still? I installed UBC 8 years ago and for the first few years was constantly presented with the no satellite signal even from very slight rain. I thought that was just the way it is. I finally put in a service call and had them come out to check things out for me and because we are very rural had a 500 baht service call to pay. It was well worth it. They ended up checking the signal strength using the regular settings from the box and found a signal strength when not raining of around 175 and were very concerned about it. They relocated the dish and properly aligned it and the signal strength improved to 255. I still get the no signal notices but it is from pretty good storms now and not any where near as frequent as before they properly aligned the dish. My suggestion is to use the Settings and check the signal strength and if it is less than 250 call them to come fix it. Good luck.

mr_hippo Posted August 16, 2007 Share Posted August 16, 2007 A quick and easy solution but please do not tell everybody. Take an empty water bottle, clear but not straight-sided, cut a slot in it and slip it over the transponder - not only will this stop the outages due to the weather but it fools the satellite into thinking that you have got the platinum package. As I said, don't tell everybody! Link to comment Share on other sites More sharing options...

I had similar problems when it rained. I thought it was normal until one day I got fed up and told the wife to call the service center. They came out tested it and made some adjustments, no problems ever since. Link to comment Share on other sites More sharing options...
roietjimmy Posted August 16, 2007 Share Posted August 16, 2007 As tigerbeer states, UBC operates on the Ku band frequency which is highly suseptable to interference from rain. If the guys from UBC positioned the dish exactly at the satellite and there no obstuctions you will have a strong signal at the dish. A lot of signal loss can occur between the dish and your decoder box however. You need to make sure all your coaxial cabling and connections are good to avoid signal loss. UBC will come to your place and check all for a price but no matter how good a job they do, expect to lose signal when a very heavy rain approaches. Fact is the UBC dish is too small to collect enough signal when it rains heavy. Military systems use a much bigger dish but who wants a 5 meter dish sitting on their roof!

billp Posted August 17, 2007 Share Posted August 17, 2007 Well, it really doesn't matter how big the dish is or how well it's aligned, satellite signals just won't pass through very heavy rain, hail or snow (not that Thailand ever has to worry about the latter). The signals are actually very weak, measured in milliwatts, thousandths of a watt. I work for an international TV station, and we sometimes lose our own signal during particularly heavy storms, even though we have big dishes on the roof, installed by equally heavy-duty engineers. But it's true that if your antenna is aligned properly, you'll increase your chances of getting a clean, stable signal. Link to comment Share on other sites More sharing options...

ignis Posted August 17, 2007 Share Posted August 17, 2007 My dish is 3.4 m, and mostly always on the KU band, never have any problem with rain, unlike the Internet when it rains I always lose the ADSL conection. Link to comment Share on other sites More sharing options...

jimmym40 Posted August 17, 2007 Author Share Posted August 17, 2007 This has been enlightening and "entertaining". I did have the UBC guys come and install the dish and I watched - they did get the highest level reading, I think it was 250. And there no obstructions direct to the satellite. Getting fed up with this UBC, I heard of a new satallite service, I'll have to do some investigation... Thanks all. Link to comment Share on other sites More sharing options...
tigerbeer Posted August 17, 2007 Share Posted August 17, 2007 the size of the dish DOES matter and also like i said before, depends on the band the satellite uses for transmitting information. Link to comment Share on other sites More sharing options...

Check out this (site only in Thai) as an alternative http://psisat.com/. Can't be too bad as their systems are visable all over Thailand. I'm not a user but sure others can give comment on PSI.

BTW, If you buy a big enough screen and projector, you can start up your Drive in Theater. only good for FTA channels. unless you know and speak mandarin or a little indian tv interests you, you basically have not much to watch. do a search on this forum and you would find many have been fooled by dreamboxes etc etc which probably gives you free "paid" tv from indonesia or the Philippines for only a couple of weeks or months at most. A reprogramming of the box is needed and that person who sold you that box sure as hel_l aint gonna give you free service. edit: i don't have UBC and i don't have a dreambox. i do however have BitTorrents Edited August 17, 2007 by tigerbeer Link to comment Share on other sites More sharing options...

silverhawk_usa Posted August 17, 2007 Share Posted August 17, 2007 I had satellite TV in the U.S.A and the system used a similar sized dish as the UBC dish. When it rained heavily or when heavy snow clouds moved in we lost the signal. Same as here (the rain that is). Link to comment Share on other sites More sharing options...

UBC in Thailand is the exact same system. Link to comment Share on other sites More sharing options...
