DMX741U C and Universal Ku LNBF

[RDosetareh]

the ku performance was also abit lower then my invacom qph-031.

The LNBF is designed for a Prime Focus dish both on the C part and the Ku part. By adding a WSKU2C Conical Scalar ring, you are changing the shape of the LNBF converting it to a LNBF for prime focus, so your C band reception will be good.

Now, as for the Ku portion, since it's sitting behind the C band and is off from the focal distance of the dish, it will not give you nearly as good of a signal as it would if it would be able to be moved a bit more towards the dish to match the focal distance required by that dish.

W.R. here, I would first say a QPH L.N.B.,, well there isn't any better! Have one on site! Love it!
That said. I will say I did lose strength in the Ku band reception, but still had enough to work. I suspect the focal point is the why?? I'm still playing with that and will report back to ya. What I was truely surprised at was how well the C band worked with out any real adjustments, the close enough method?
I'm retired and play a lot and will keep you posted as to how it works out. I also have a " Bud " but not stood up. I did have the 4 footer ready to go and thats why I tried the new L.N.B. , still basically happy and not yet really tuned in! Again I'll keep ya posted!

dont get me wrong. the ku performance was good. and the cband "good enuff" performance is exactly that. it was easy to lock. i just couldnt achieve anything stable on my 39" pan this far north. a 4ft dish would be a nice toy to play with but with 3 10 ft dishes at my disposal (and all free) there is no reason to spend a couple hun on a 4 ft dish. and a conical scalar in my parts box won't hurt either. ive spent way more on way less so... i just cant wait to see this lnb perform on my 10 ft solid dish i scored. hopefully i get my pole up this week. and ill post results.

Mr. Crackt
W.R. here. I haven't played with mine as its been windy here, trees down windy! Tough to site one in when it's like that.
I also have a big old bud setting. I chose to try the new LNB on the 4 footer as kind of an experiment. I really didn't expect it to preform near as well as it has on the small dish. I'm seeing on other forms that folks are using them on 36 and even 32 inch dishes and seem to be happy. I would expect working on only strong single feeds?
I did have to make a new holder for the LNB as the one provided wasn't right for my dish. I made the angle's adjustable figureing it would be critical and very touchie. It wasn't! I got signal when it was way off, not saying it was great or worth having but enough that the reciever saw it and we could steer and tune from it. I was very surprised figureing it would be very fussie. I did start with C band.
I'm in Minnesota between Duluth and the Twin Cities. Near on a straight line, near exact center. With a 39 inch dish I'd expect you could be up working, not 100% but working reasonable well. If I may, were are ya located aprox?
If I sight 99 degrees, G16, I get the big networks from the caribean, I get them great with extremly good signal. Signal I'd have expected from the big old BUD! I do think it cost me signal on the Ku band. I no on 123 that some signals are very strong and some are lacking. I had all these signals good befor the LNB change. After, The weaker ones are fussie. But again I haven't really tried setting things or really tuneing things in, were running on the close enough start up setting yet. The wind has put a stop to adjusting things, got one more day of wind here.
If you try the big dish please keep us posted as I would consider going that route to if it really works out.
I again stress that this LNB gave me far better C band then I ever expected. It however did cost some signal strength on the Ku side. That said, I'm watching the same T.V. Ku side I was befor we did the change and now have gained the C band side. Was kind of a balance on signal strength but the T.V. set is still showing what we want to watch! There's much more on those satellites that I'm not gona watch so I don't care if I get. My goal is family T.V. not can I get it all cause its there!

im at 51 n. central canada. i was surprised with the cband performance too. i did lock some stuff at 72 , 99, 121. i believe. but it just was on the fringe of watchable on a clear night. i suspect the focal point of my dish is not very cooperative with the lnbs requirement. it seemd the lnb wanted to be further from the dish than the scalar would allow (the conical scalar had to be set at a position thatd make it bottom out on the 65mm bracket). im not dissapointed with the performance at all. i bought it as a toy and ive played with it so it money well spent in my eyes. im all about trying new things so. either way i think leaving the invacom on the 39" dish and setting up the bud will be by far the best solution. im off to the shop again to finish welding up my pole setup for the bud. now just for some dry weather so i can pour some piles and stand that 10 footer up.

I didn't realise how far north you are. I do suspect the 39 inch dish will leave you short. That said if you go with the BUD your C band ought to be great as that seems the high point of the new LNB, the Ku should do fine purely due to the over sized dish. Keep us posted!

HI,
I have some problem to decide, because one thing I don’t understand fully:

They mention 4DTV ??? means For Digital TV? In Europe 99% is Digital in Ku band…



Horizontal/Vertical in Ku, also left and right circular (in C), depending the satellite TV-stations



I like very much the (convertible) package to be put on an offset antenna/dish, the ones (big and small) we use for Ku here in (belgium)



Please tell me , reception of e.g. Astra 2 at 28.5°/Astra at 19.2°/ Hotbird at 13° East (Ku-stations Vertical/ Horizontal)

and e.g. PAS at 68° East, some atlantic/brazilian satellites in the West too (mainly C-band-stations circular L& R)



satellites with their specifications

What would you suggest?? or confirm?? Combo pack with DMX741U C/Ku LNBF with Universal Ku????



For I believe in this left combo Pack for Europa (to get near Asia till 80° East and some American special beams from/till 70°West)

for we live at 3.1 East, we can take quite a lot.



In the COMBO is NO DIALECTRIC PLATE?, otherwise in some pictures they mention this plate is necessary for circular and linear satellites….

So, do we need it? When do we need it? Depending type of the dish? Or??? What is it separate cost price?



Please help me out Thx

You need the DMX741U package.
