Thread: DMX741 C/Ku lnbfs

I was thinking about giving one of these a shot on my 10 foot dish. Has anyone here on this site had any experiences with this DMX741 C/Ku Standard LNB C Band Ku Band? If so what did you like or dislike about it?

I was wondering about the Skew and how it works with several satellites?

I am concerned with my dish type being mesh but I was told many moons ago it would work fine with Ku...

I seem to recall Linuxman saying nice things about it a while back:

Test, Comparison, and Review WS International DMX741 C/Ku LNBF

Sweet Review! Well that settles that heading to see where to buy one...

Thanks Anole!

Galaxy Marketing (sponser) has them

Is there anyway to use one an offset dish or would it be a waste of time?

Some folks have 6' offset dishes, and I believe it works okay, with a conical scalar.

For the 4' mini-BUD crowd, none of the dual-band LNBF's seem to do well on Ku, but do work on C-band.
Again, you'd want a conical scalar.

One of our members reported the C2 seemed to outperform the similar Ck1, at least for MiniBUD C-band operation.


Sadoun carries all

the GeoSatPro Ck1 & GalaxyMarketing DMX-741, the conical scalars, and the C-band only C2.

If you must do it, do it. But I am in the process of changing my two BUDS to c-band only Orthomode Feeds. I used CK-1's on them, and while they worked, I knew the C band could be better, and the Ku, well, my 1m Primestar kills either of the BUDS for ku.

Does it work? Yes.
Is it easy? Hell No. Its a PAIN to get it correct enough to get C and Ku the best they can be.
Would I do it again? ONLY if I had no other choice.

Well the thing seems to get decent reviews when reading about it...but the thing that concerns me is the Skew...I am sure of one thing I am too old to be running outside to a 10 foot dish trying to adjust the damn skew manually.

If it would get several good C-Band and Ku Satellites...That would be ok..I think it would be very hard for it to get all of them...The skew is where it's going to go south on... I did notice LAK seems to have good luck with his and I am wondering how well it does work for him on his 10 footer and what Receiver he uses?? I also wonder if this thing should be setup on your true south satellite?? If it does that's going to be a real pain in the *** for me as that dish is pretty high off the ground and on a hill to boot...


I have 2 Primestar dishes and infact I was trying to get one of those on a Satellite Yesterday. I had good signal on my Meter But the receiver showed nothing. I tried my best to remember the Correct LNB settings for the thing and just settled for 10750 and Standard as the type and still nothing. Pretty sure the LNB is working but I am almost certain I got some of the settings wrong for that LNB...I know one of the Dishes worked as I have used it before but it's been a while. The LNB's are the type that has one input and I think best I remember uses 22hz to switch polarity but again I don't remember it's been a long time...I think also they are linear lnbs but agian I don't remember..

but the thing that concerns me is the Skew

Skew is automatically adjusted when the Dish Moves, just like a Motorized Ku Dish
Ideally, you set with Dish a True South, but as you said not always easy.
What I did was drive the Dish to my true south, then disconnected the Actuator from the Dish Ring, and carefully walked it down to one side. Installed LNBF and reconnected to Arm.

The unit works and is very convenient, but no match if you are in a Quality Reading race, or very weak feeds.
