Linear Ku LNB for 125W

[hondoharry]

I need a linear LNB for 125W. I'm confused about the LNB's where some are 0.1db, 0.3 db and 0.5 db. What's the difference?

What are the brand/price options and the best place to buy online? Any recommendations appreciated.

I bought some cheap 9750/10600 0.1db LNB's and they miss some transponders. Tried two and each one misses different TP's. Frustrating!!

Try selecting the transponder you keep missing and skew the lnb to maximize quality on those transponders and then scan.

Thanks for the help. I know the skew is correct but some TP's just show no quality at all while the same TP shows quality on another LNB but that LNB misses different TP's. They're both POS's.

Is your dish large enough for 125? You should have at least a 30" but the larger the better.

Spitfire 0.1db lnb are good, You got to play with the skew until you get the best quality, what are the quality on the other tp like?

I use a universal invacom lnbf but they don't come cheap. Skewing an lnb is usually the best way to solve the issue but many receivers are usually to blame as they miss tp quite often. What receiver are you using?

On the good TP's I'm getting around 50 Quality with a 0.90m dish (35"). Since no motor, no need for the Invacom.

I've seen 0.1db, 0.3, 0.5. What's the difference?

N o major diff at all, what receiver are you using?

0.1db, 0.2db, 0.3db ect... Is the noise level of the lnb, I haven't test it but it is said, the lower the noise level the better the lnb, for satellite with strong signal it is not necessary but for the weaker ones it counts.

A "Q" of 50% may be all you can get with your current setup, remember this is a digital signal, you don't need every micro-volt of signal you can squeeze out of the setup like you did back in the analog days.

If 50% is all you can get then you may need a bigger dish, as that would be the best way to increase the "Q", 90% of the linear satellites out there now have about 1/2 the output power that the Dish and BEV satellites do.

I have a 39" dish and with some very fine tuning and tweaking of the skew, 70 to 80% is all I can get on most linear satellites, (I also use a motor) these birds were originally used for "C" band, "Ku" band was added on the newer birds as an afterthought.

So, most of the linear satellite signals were to be used with 10 to 6 foot dishes that were modified (dish mesh size was made smaller) to be used for "Ku" band, that way you could pick up both "C" and "Ku" band signals.

If you have 50% "Q" now on a .3 dB noise floor LNB, going to a .1 dB noise floor LNB wont make that much of a difference, going to a bigger dish will, also using a higher quality coax can help, but not by that much.

For every 3" increase of dish size will gain you about a 2 to 3 dB of signal increase, depending on the receiver this may give you a 2 to 6 % increase in "Q".

I was testing with a Skybox F3. When I put on an old Coolsat brand 10750, all the TP's popped right in on the 9600/10750 LNB setting. The other el cheapos were 9750/10600.

[Costactc]

Universal setting: 9750/10600

Regular linear setting: 10750

Channels should scan in with the F3 without any issues, I have one that I'm using also on ku band.

Correction, the Coolsat 10750 came in on the 9750/10750 setting on the Skybox, not 9600/10750 which doesn't exist..
