HI ALL I NEED SOME ADVISE. WHAT IS THE BEST SINGLE LNB TO USE WITH MY 33'' ELLIPTICAL DISH - MOTOR OPERATED - USING A i-LINK RECIEVER . I WAS TOLD IT WAS BEST TO USE A SINGLE LNB WITH A MOTOR DRIVEN SETUP?? I WOULD LIKE TO PICKUP CHANNELS OF NEWS AND IMPROVEMENT TYPE SHOWS.I AM IN THE 21562 ZIP CODE AREA.I AM GREEN AT THIS ANY HELP WOULD BE APPRECIATED. RON BLASTERBOY

no reason to shout (aka turn off the caps lock)
so a few months ago when you asked the same thing you still havent got a new LNB?

Yes your right .You didn't help then and not now. Sorry if I offended you by shouting . As I stated today I am green at this and need help. If you can only help in the key board dept. then maybe there is a more knowledgeable guru of the FTA that can lent a hand.
With one motorized dish i would use an Invacom QPH-031 Quad-Polar LNB as pictured in my avatar. It is both Linear FSS and Circular DBS in one. Not much for circular transmissions right now but you can get "Charlie Chat" on 119W. You would also need a switch to select from the different outputs of the LNB.
The LNB is just one part of the equation. Dish, cables, feedhorn, connectors and switches all should be factored in. I have had good signal levels with Invacom and DMS, but certainly believe there is better. The Norsat line have some great performers, but can be get costly. This is here say as I have not owned a Norsat. Look for a low number on the noise factor, but do not be too concerned about one brand being a little noisier than another as they are not all measured the same way. Look for good stability. (i.e. low amount of drift)
LNBF
Since you only asked for LNBf recommendations, here are a few that I doubt anyone will argue with.
Which you choose might depend on whether you need to watch any Atlantic birds, and need a Universal LNBF or not.
SatelliteAV GeoSatPro Standard single output
SatelliteAV GeoSatPro Standard dual output
50% off GeoSatPro LNBFs for the holidays
Galaxy Marketing DMX 521 Standard single output
Galaxy Marketing DMX 522 Standard dual output
Others are good too, but the above are reasonably priced and come from our Forum Gold Sponsors.
edit: Oh, and this one too!
Invacom SNH-031 Universal single output (I have one of these)

Your previous post asked about 5 lnbs on a motorized dish. Anole directed you to getting multi lnbs on one dish and asked some questions - yet to be answered. Even the best guru can not answer an open variable question....
There are almost as many answers to that question as there are people on this forum. I am on dial-up, so my search never finished. What is an I-link receiver? A 33" dish is minimal size, How much weight can this unnamed dish hndle? I am using a stock lnbf on a 75E Primestar dish on the roof of my motorhome.The motor is a V-10, But it is difficult to aim with the motor(home)! (read that as a joke, please.)
Please pass on more information and someone would be able to give better information. Is trhere a lnb mount on the lnb arm and if so what size holder --- That makes a great limiter to the answers. What signals do you want to capture?

An I-Link receiver in most cases is not a good FTA receiver. It has an Ethernet port for (as sites say) "automatic updates". You can read into that as much as you wish.
Now maybe the OP bought it because some salesman said "it was the best" but you posted a real good answer. There are too many variables to give a good answer.

Good questions get good answers, crappy questions get sh*t for answers.
btw CAPS is considered yelling and therfore rude on pretty much every forum on the internet, its not something unique to satguys.
I use an invacom qph-031 and its by far the best ku lnbf Ive used so far. excellent noisefloor. Many manufacturers write the NF on the side of the lnb, 99% of those stickers are crap. SatAV posted something to that effect once before even.

Hi Blasterboy,
The invacom qph-031 does both linear and circular Ku, for most FTA you only really need a linear LNBF since the circular is almost exclusively for non FREE satellite reception (with the exception of some surprise ITC transmissions). Stating that you have an I-link receiver leaves much to interpretation, is it HD capable? AMC 21 (125W) has PBS and other programming that appears you are looking for. There are even HD channels, but we don't know what receiver you have and if you want HD then the 33" dish maybe a bit small. You may wish to check out "the list" for channels available.
Taking into consideration that English is probably not your first language:
Anole has sent you some good information and rv1pop has probed you for more information. Asking a question in a thread and then repeating the same question (In CAPS) without acknowledging the first post you made is just plain "not nice".(Pissing off the moderator doesn't help either)
If you feel you were misunderstood in the first thread then you need to have more CORRESPONDENCE (yes I did shout).
You are "green" you admit it, that's cool... Everyone needs to start learning some where. But, just because you ask a question in a forum doesn't guarantee an answer. And if the answer you get isn't what you think it should be... Asking it again in a different thread DOESN'T HELP.
Nobody here "HAS" to give you help, so don't act like it's your "RIGHT" to get any.
Have you heard of the old saying "You attract more flies with honey?"
There are so many knowledgeable and helpful people here on satellite-guys that the one thing I fear from your correspondence so far is that
you'll miss out on it.
So let's start over, shall we?

Iceberg is probably a walking database of satellite info and probably forgot more than most people will ever know!
Anyway, instead of starting a new thread I thought I'd add to it.
First I have a Super Dish and a nice Primestar (Round metal one). Mounting a feed may take a bracket or whatever but we all know it can be done with duck tape if you want to.
My question is. Is there really a need for circular and linear feed on a dish I listed?
I have been looking at:
DMX522 Dual Twin Double Ku Band Linear FTA LNB- LNBF
0.2 dB Dual Twin Double Ku Band Linear FTA LNB- LNBF HD - eBay (item 220592478469 end time Jan-14-11 10:51:34 PST)
and:
Digiwave DGL1189S CIRCULAR / LINEAR DUAL KU BAND LNBF LNB
NEW CIRCULAR / LINEAR DUAL KU BAND LNBF LNB - eBay (item 190369251400 end time Jan-24-11 16:45:26 PST)
I have a Viewsat Ultra that is going to be used somewhere like maybe in the basement with all my junk (my playground). I plan to motorize the dish, most likely the Primestar because it is so nice...It may end up with more than one LNB too, even though I'm gonna put a dual output on it to begin with. Might not have to put a motor on it...
Oh, before I forget. I have probably ask this question a few years ago but my neighbor had a tree growing and was not going to cut it down. I would've had to mount a dish on a 50' pole. She got a new pool and is cutting it down. I have already ordered a S9 and a Vbox V3000 (not here yet), a standard DMX741 (22 KHz switch version, already in use on my 6' Perfect 10 and love it), 4-way splitter with one port voltage pass thru, and a 4 port DisEQ switch.
I forgot to yell a little bit! HOORAY, SHE IS CUTTING DOWN HER TREE!!! HOPE TO BE UP AND RUNNING GOOD BEFORE SPRING!!!!
I have a good start!
Also didn't aim to hijack the thread but we are discussing the best LNBF for a smaller (not BUD) type setup.
I've already spent a good deal of money and wouldn't want to waste any now or otherwise screw up.

The function of the 118.8° + 119.0° LNBF was to receive two Dish Network satellites.
Both transmit circular. 119° uses 11250 LO, and 118.8° uses 10750
(as best I remember)
It is possible to scan up into the DBS band with your 10750 LO, so that's how the LNBF gets both.
You do not tell your receiver the LO is 11250, because it's not.
The LNBF has no switching between birds (shown in their specs)
This is a device developed for hackers, originally.
Anyway, getting linear signals on an LNBF designed for circular will work, but there is a significant loss so signal strength.
You cannot optimize it for both, with such close frequencies.
So, I will say this even without testing...
I wouldn't take the Digiwave for free, if someone sent me one!

I assumed one output was circular and one linear...like the invacom quad deal. I'm also thinking about adding another LNB to the BUD because it has 2 RG6's already ran to it. Used to be one C and one Ku. With the DMX741 I am only using one so a second LNB would be easy to hook up by hooking it into the switch in the basement. I could put a switch under the LNB cover too....as the DMX741 uses 22 Khz switching and still be using one cable to it. Searching about adding a DBS or FTA(style) LNB to a BUD. Don't want DBS.
I really like this DMX741 except for the plastic stuff...and that DMX522 looks pretty good. At the start of the thread they said watch out for drift. It specs at 70 db gain, +- 1 MHz and 0.2 db noise:
Input Frequency Range 11.7 - 12.75 GHz
L.O. Frequency 10750MHz
L.O. Stability 1 MHz (-40 - +70° c)
Ouput Frequency Range 950 - 1450 MHz
Noise .2 dB typical
Conversion Gain 70 dB typical
Input VSWR 2.5:1
Output VSWR 2.0:1 (max)
Connector F Type female
Impedence 75 ohm typical
Cross Polar Isolation >25dB (min.)
Image Rejection 45 dB (min.)
Phase Noise -50dBc @ 1 KHz
-75dBc @ 10 KHz
-95dBc @ 100KHz
Supply Voltage
Ca: 11.5 - 14.0 V = Vertical Polarization
Cb: 15.5 - 19.0 V = Horizontal Polarization
Operating Temperature -40 - +70 degrees Celsius
Storage Temperature -40 - +80 degrees Celsius
Relative Humidity 0 - 95 %
Throat Diameter 40mm
Oh my, and to think a couple weeks ago I had no choice...TREE!

Dont believe the marketing hype! There is not a .1 or .2 NR LNBF especially with 70dB gain on the market!
Nearly all LNBFs sold are between .6 and .8 with gain of around 60dB and +/- 3MHz drift. The only way to get a lower NR of .4 or .5 with 60dB gain and less drift is to have the factory sort and collect the higher performance units for a premium price.
Manufacturing specifically for gains of 60dB, below .4 NR and less than 3MHz drift results in a product factory cost in excess of the retail price of the units currently marketed as .1 and .2 NR.
Thank you! I know those marketing guys get paid to spec it as good as possible...
I had a .7 Ku on a Corotor II with the servo. It done very well and when I switched to the .2 DMX741 it may have gotten a little better...I have not peaked it good...too cold. I just inserted it into the corotor ring and called my old lady on the phone and had her tell me what it was....Rocket science, I know.
Ok, aside from the numbers on the label, can someone give me numbers from their point of view (real world)?
The spitfire is making a lot of smoke....but I want dual output. The DMX522 still looks like the best deal.
My testing of several Ku Linear LNBFs rated from .1 to .6 indicates that as SatelliteAV states above, there is very little if any difference in actual performance when tested on the same dish, on the same day, and the same satellite and transponder. With 6 feet of RG-6 and a Coolsat 6000, there was no measurable difference in signal quality when tested on the same weak but stable signal.
