jgarg,
Are you in Australia? I wonder what Satellite receiver box and size of the dish have you used? and you can pick up HTV, Thuan Viet channel ok? what signal quality can you get may I ask? Your feedback is greatly appreciate.

Where can I buy (or where did you buy) the Yuri LNB?
Anyone knows a cheap retailer for a 3M Sat Dish.
I rang up the guy who installed my system 3 years ago, he said the 3M dish would cost $700 for the dish itself, I think I have came across a web page the normal 3M dish is about $370 but I forgot which web page it was.
The Yuri LNB is the last resource before I will spend some $ to replace my existing 2.3M dish, it's a one-off money spend so I think it worths it.

jgarg has already stated his dish is 2.3m mesh and his profile says he's in Melbourne eastern suburbs (Australia).
giangs,
As above... possiblt just a better LNB and accurately adjusted on a 2.3m dish.
Remember, the bigger the diss, the stronger it needs to be, so a good heavy duty 3m mesh dish typically sells for $500 to $800
I've never used Yuri LNB's but from comments I'v read, they perform quite well.
I've installed CalAmp and Norsat... excellent LNB's, but with separate feedhorns, they can cost up to $800.
Obviously, they are intended for commercial use, but there are some keen (and rich) individuals who want the best performance.
giang,
For 3m dish, you may need to consifer wind loading so for gusty wind condition, it can withstand the loading and at the same time it may not damage your roof (if it is roof mount), for my case, I will consider adjust the dish and may change to the better LNB. If all can not work out then change to 3m dish is the last resort

I'm lost, don't know which one to buy.
Which one is for FTA, C band and good signal pickup?
You can cross many off that list and LNB's don't care if you use them for FTA or PayTV. You need a LNB with an LO of 5150mhz/C-band.
I personally feel the gain from a better LNB will not give you a signal that is that much better than what you are already getting. I reckon the larger dish is what you need to look at.

You are probably right.
However, I just want to try spending small first, then spending big later.
I still have 4 more Satellite systems from my relaltives who will learn experience my "guinea pig" system so they upgrade their system.
What's is the difference between LNB and LNBF? or are they the same?

Giang,
my brother just remind me that you have to make sure your new LNB mounting diameter is the same as the existing, otherwise you may need new mounting kit which is quite trouble some.
He also advises that the lower noise temperature (Kelvin degree) the better
Keep me post about your adjustment, I am still waiting for the installer to come over adjusting my dish.
Last night, I try to delete all the channels and re do the blind scan, all the HTV channels disappear but VTV, I assume that the signal for HTV are quite weak so it does not appear.

Most of the LNB's you've listed are Ku Band...
As mentioned, you need C-band 5150MHz LO and from that list, there's nothing that stands out, except the Norsat, which is only single polarity and is priced over a thousand dollars... and you'd need to buy a separate feed horn on top of that!
Unfortunately I sold my 3m dish and haven't put up it's replacement yet (3.7m) otherwise I would have been able to check reception as a comparison.
(too busy installing others to do my own)
As mentioned, the noise temperature of an LNB is usually a good guide, but a lower figure doesn not always mean it will perform better.
The best performing LNB's are the PLL (phase locked loop) type... but they are expensive... a bigger dish costs less.
Another consideration is... can you physically fit a 3m dish and are there council permit restrictions applying to dish size/height in your area?
Try the Star 3009 C-band LNBF. Seems to help a lot on this bird.
Have tried a Supernet HL-222. The supernet output plenty of strong signals but none of them seemed to be real! That is: It created them all!
Uh Oh Oooops!
Which make/model of LNB are you using?
The actual quality levels don't change with diferent receivers.... only the displayed values, which are usually not accurate anyway.
They are an indication only.
You could have 10 receivers of the same model and you'll likely see 10 different readings.
For the signal readings to be accurate, the receivers would cost thousands of dollars each.
Eg: the spectrum analyser I use to align dishes & LNB's costs $10K.
