I was wonder if any of you use a SMW Type R Ku Quad Band LNB and what receiver your using .The Spec of the LNB is :-
Lo 10.00 ( 13v . No Tone ) 10.95-11.70 Ghz
Lo 10.75 ( 13v , 22Khz Tone ) 11.70 - 12.25 Ghz
Lo 11.30 ( 18v , No Tone ) 12.25 - 12.75 Ghz
Lo 9.75 ( 18v , 22 Khz Tone ) 10.70 - 11.70 Ghz

I was wondering what receiver you were using it with and what LNB settings you set the receiver at .

Almost any receiver could be set to use that LNB. But the question is why would you want to use that LNB? You need to understand LNBs a little better.

Yes I thought the same but this SWM Type R its a bit of a odd ball , If you switch the LNB settings to Universal 9.750 - 10.600 it would seem you only get 2 of the bands .
Lo 10.00 ( 13v . No Tone ) 10.95-11.70 Ghz
Lo 10.75 ( 13v , 22Khz Tone ) 11.70 - 12.25 Ghz
Lo 11.30 ( 18v , No Tone ) 12.25 - 12.75 Ghz
Lo 9.75 ( 18v , 22 Khz Tone ) 10.70 - 11.70 Ghz

This is why its not plug and play like your standard Universal LNB , Since this is a commercial Quad band LNB not sure what is the best receiver for it .

My thoughts so far are you won't find a consumer hobby receiver that is fully compatible with this LNB. It's a professional grade LNB designed for professional systems. These are your options with the Technomate TM-5402

SMW LNB, frequencies correct, polarisation as per position name:

Technomate position nameLNB settings, all singleASC1
1. 4.8e 10.7-11.7H18v, 22khz on, LO 9.7504.8e H
2. 4.8e 11.7-12.25H13v, 22kz on, LO 10750 4.8e H
3. 4.8e 12.25-12.75H18v, 22khz off, LO 113004.8e H
4. 4.8e 10.7-11.7V18v, 22khz on, LO 9.7504.8e V
5. 4.8e 11.7-12.25V13v, 22kz on, LO 10750 4.8e V
6. 4.8e 12.25-12.75V18v, 22khz off, LO 113004.8e V

With SMW set as Universal, frequencies incorrect, polarisation as per position name:

Technomate positionLNB settingsASC1
1. 4.8e Ku HUniversal4.8e H
2. 4.8e Ku VUniversal4.8e V

With a universal LNB, all frequencies correct, all polarisations correct, auto polarisation:

Definitely a challenging one. I don't think you'll find any of the usual "LNB type" settings will work, especially in Europe where the entire KU band is used.

You might have to set it up as several satellites using different LNB settings, just to cover the spectrum
- one with voltage set to 18 V and LNB as universal but with modified 2nd LO set to 11300, that would cover 10.7 to 11.7 and then 12.25 to 12.75
- a second satellites with 13V, 22k on, just to cover 11.7 to 12.25

You can't use a Universal LO on this LNB. Like I said you need to understand how an LNB works.

Just some examples of how you use this Specialty LNB. .
1st. This is a single polarity LNB. So it must be orientated on the feed horn in a Vertical or Horizontal position depending on the transponder specs.
You can't use voltage switching for polarity control with this LNB as it uses voltage for band switching as well as 22khz tone.
So lets say you want transponder 11065 H 2000. You set the L.O. to 10.00 22khz is off and you want the voltage to be 13V. With a voltage polarity control looking for a Horizontal transponder you will be sending 18V instead of the required 13V Some receivers have a voltage option you can set. Others you can lie to it and tell it it's a horizontal transponder since the polarity is determined by how it's oriented on the feed not by voltage.
if you want 12400 H 30000 you set the L.O. to 11.30 , 22khz off, voltage to 18V.
The LNB has four different L.O. settings listed on it and the frequency range it covers.

... you won't find a consumer hobby receiver that is fully compatible with this LNB.

Well, in relation to the IF of 950 - 2150 that a receiver can handle, I see no incompatibility issues.
When using the universal LOFs, it is just that the frequency and polarization shown on your receiver, doesn't match the actual frequency and polarization.
If you want frequencies shown right, you'd have to set up 4 satellites, each with its own LOF (the actual LNB LOF).

Another thing that would interest me, is, if the 4 'bands' of the LNB really do a cut-off at the max IF-frequency.
E.g., when using Lo 10.75 ( 13v , 22Khz Tone ) 11.70 - 12.25 Ghz, giving IF 950 - 1500, would there be a IF 1550 for 12300? (As the receiver would pick up IFs up till 2150...)
Because that would mean, when defining a single satellite with universal LOFs, that some programms would be listed twice, when doing a blind scan.

sub101uk, just curious what feed horn you are using, can you switch polarities? Doesn't look like a common waveguide connection for Ku.
Funny they would seperate the Ku band into 4 sectors rather than two. Makes it interesting to play with though! :)
Agreed most FTA receivers should work fine with it; as long as you can enter the LO frequency manually. Some receivers might even allow you to set it up as a universal if you can enter two LO values so you would only need to program in two satellites instead of four.

O, I forgot to check.
There is at least one parallel thread about this; information that is alas not shared with us.

So my reaction is sort of copy of what already was posted elsewhere. Sorry that I posted, and took the effort....
I'm out again!

Many Thanks to all those who replied yes it looks like the only way to use it is with 4 x separate satellite settings . The LNB a SMW Type R covers Ku Quad band LNB

Lo 10.00 ( 13v . No Tone ) 10.95-11.70 Ghz A
Lo 10.75 ( 13v , 22Khz Tone ) 11.70 - 12.25 Ghz B
Lo 11.30 ( 18v , No Tone ) 12.25 - 12.75 Ghz C
Lo 9.75 ( 18v , 22 Khz Tone ) 10.70 - 11.70 Ghz D

Or Dump a 500$ LNB and start all over again , Its being used on a Corotor so the LNB needs to have a WR75 flange , So what other Ku Quad band Lnbs with a WR75 flange are available ? I see that Norsat make one but you seen the silly price . The only Option for LNB settings are Universal , OCS , SATCR or Single at the moment the Lnb is set at 9.750 - 10.600 . There are 2 other settings 9.750 - 10.750 + 9.750 - 11.300 on both of these settings the receiver a Technomate TM-5402 crashes and locks up at about 22% So at the moment I have it working on Universal settings at 9.750 - 10.600 and receiving 324 channels on Astra 4A / Sirius 2

What seems to be the problem the last time I put a topic on ths forum on the 29 th May 2020 You came up then with a load of strange replies " What is wrong with you my friend " ? I am looking for help to sort this problem out and your not helping . If you have some thing to add to the topic please add other wise please go away .

To the other guy who gave there feed back many thanks .

Nothing wrong with me, mate.
Did you understand what I wrote May 29th, post #11 ?


I am looking for help to sort this problem out and your not helping .
Well, as you can see in post #7 above, I did analyze your problem and was certainly trying to help.

Alas, it was help that was more or less a duplicate to the help you already had gotten elsewhere, I discovered later on another forum.
So you are letting multiple people doing exactly the same helping at the same time, but don't let these people know what help you are already receiving, and what help you have already received.
Offering twice, thrice, or even more times exactly the same help to one person I find pretty useless, and frankly a waste of my time.


So, I repeat, I'm out again.

As I and many members of this forum have said to you over and over again , There is no law that states you cannot ask the same question on other satellite forums if there was any problem with my question I am sure admin would remove it . The only person who seems to have a problem with this is you ?

If you have any information regarding my problem with the use of a SMW TYPE R Ku Lnb with a domestic receiver and what LNB setting should be used I would love to hear from you other wise I see very little point in any replys that you may give .



So back on the topic if the SMW LNB cannot be used with a domestic receiver what other quad band LNBs are there available with a WR75 flange since its going onto a corotor I see that Norsat make 1008xu quad-band ku but looking at the spec it looks like it could be the same as the SMW Lnb and in that case only suitable for commercial receivers should this be the case what other quad band Lnbs with a WR75 flange are available .

Many Thanks
