My SAT-playground

[margusten]

chap from another forum did all the calculations and drawing

Hi, can You post a link to this forum.
Interesting modification. So You cut out original feedhorn part from BU.
I can try this on My 3M link dish. F/d=0,3

If you are happy with my drawing, there it is . Download it and print in such a way that size on paper is same as digits on the drawing.

There is family of Channel Master antennas gathered for photo-session ;)
I am missing CM 0.75m badly

 

[Captain Jack]

And you need to fix the 35cm one to function as a dish

 

[RimaNTSS]

This is unimportant detail. Anyway, the dish is nice and unique. And, BTW, you are God-father of this dish

 

[RimaNTSS]

I know, it is still some time till X-mas, but weather was OK today and I decided to do some decorations. in the yard. ;) It is only 14 meters of lamp string is needed to do one loop. I think I will make some decorations to other dishes as well.

I've got new toy today. Another toy (CAM-module with card for several 4K channels) will arrive soon.

 

[Ghostleader]

What configuration of tuners did you get RimaNTSS? I see there's a "+1xDVB-T/C" so it has an added DVB terrestrial/cable combo tuner as well as how many sat tuners?

 

[RimaNTSS]

@Ghostleader I added to the default C/T/T2 tuner and 1tb hard drive. Exactly this combination GigaBlue UHD Quad 4K Receiver 2x DVB-S2 FBC 1x DVB-C/T2 Tuner | GigaBlue | HDTV-Receiver (Sat) | Digital Sat-Receiver, accessoires - hm-sat-shop.de

I'm curious for the performance of Gigablue:
-What are some weak signals that still can be received? (And, of course, with which dish and LNB ). And how is the low signal reception compared to other receivers?
-How low is the lowest symbolrate that you can receive?
-Which multistream/PLS/MI-T2 transponders van be received?
-Is blindscan possible? If so, what's the performance of the blindscan?

 

[RimaNTSS]

@Lexzie so many questions to which, most likely, I will not be able to give objective answers. I am using for many years in parallel Dremboxes (7000s, 500s, 600s, 800s, 8000) and GB receivers (GB Quad, GB Quad Plus, and now also GB 4k). TBH, I do not see much difference in performance of those 2 brands. I think it is not easy task to compare 2 different receivers. Quality of the displayed picture is also very subjective. Of course, 4k is much faster receiver than anyone I've used before.
What I can, and probably will do- will choose some transponder from Astra 2E (UK beam) and do signal level monitoring on GB 4k and DM 8000 and then try to compare results.

 

[Lexzie]

That's nice, but all the other questions I find much more important.
About if the GB can receive multistream, low symbolrates (how low?), DVB-S2X? and if GB has a blindscan function (and does it find all frequencies?).

 

[RimaNTSS]

@Lexzie Will check all that due time. But, it would be much easier for me if you give me some examples of transponders (multistream, low SR, DVB-S2X). With BlindScan I have very small experience and it is not so positive because of the fact that after blind scan frequencies from different satellites scanned and made a big mess . But, will check that possibility as such.
Add later: Yes, there is Blindscan. How good is it.... I do not know.

 

[Lexzie]

I will give some examples ASAP.

 

[RimaNTSS]

Let me predict:
- multistream- NO;
- DVB-S2X - NO;
- Low SR - perhaps.... but not very low.

 

[Lexzie]

No multistream and no DVB-S2X surprises me, this article says all Gigablue receivers (with the right tuner) should have it: Multistream - OpenPLi Wiki

 

[RimaNTSS]

That was just my prediction. Will check it someday.

[Lexzie]

Thanks for trying. Could still be depended on the image you use and if you have the new NIM SP2246T tuner.
