Black Ultra Twin & Single LNB comparisons

[hairybadger]

That would tie the dish up, so you couldn't zap to a different satellite.

Well, yes, obviously..... "so that I can record a program on one transponder while watching one on another on the same satellite"

That would drive me crazy. On my Ultimo all four tuners are completely independent of one another.

It's a compromise. I have the T90 for regular watching, the other (smallish) dish on a motor is really just for playing.

Have just ordered an Inverto Black Ultra High-Gain Single LNB from the uk, status shipped, on arrival will compare its sensitivity against the Inverto Black Ultra High-Gain Quad LNB on the same setup.

Looking forward to the comparison.

 

[skomedal]

Shall keep you informed.

I have seen a post from you saying BU LNB feedhorn Is optimised for low Ku band better then Andrew feedhorn
would you explain why Is that - Is there a specific scalar proportions
I like to know how scalar ring proportions - ring height and distance relate to reception In Ku band

Inverto ultra black single versus quad signal strength fringe reception astra 1N @28.2E bbc/itv from central southern norway, 100 cm tm dish, tm5204 hdci m2 stb, 5 meter brand new high quality copper braided coax.
Comparison done on the veranda thus could bypass the diseqc motor clear blue sky temp ~+20c, every position ( every 2 mm with skew test left center right ) tried on the long necks ( had hoped the extra longneck on the single would let me find the sweet spot on the dish ) spent 4 hours testing ( dish is mounted head height at the end of the veranda firmly anchored top and bottom ).

Conclusion :-

The quad had a slight edge over the single on all TPs ( 8 ) tested signal strengths on the quad were level 96/97 quality 88/92 the single were level 96/97 quality 85/92.

Also tested a wildcard LNB the Maximum v4 quad 0.2 Db on the same setup and TPs results were level 97 constant quality 90/95.

As you can guess I have left the maximum in place.

Hope this helps ppl with fringe reception.

Regards

Ps. Also tried all the TPs on astra 2F level 97 quality 8 so no lock.

there are better than ultra black LNBs
look here _http://forum.dxtv.de/wbb/thread.php?threadid=21167
and that Is not all because BEST HG model has even better gain

Shop owner Ponny told that member Elchromo has very good results with that lnb , listed at satshop24 as a PLL (X-tal controlled lnb)
I ordered 2 to test , therefor i modified one to direct2fibo .
I noticed there were 2 adjustment screws at the body , normal for the common DRO lnb's , so i opent one and there are no X-tal in it .
At my test i could find some TP's were stronger and some weaker according to the BU , overall the same result .
If someone's interrest is on such better performing TP , than the BEST lnb is for you the winner .
I mentioned the lack of those X-tal at that forum , but Ponny did not react , so i wrote him a PM .
Without answering or comment , he changed the advertisment to very stable occilator

thank you for Input
which freqs are stronger and which weaker according to BU - I guess you are talking about single lnb
have you tried HG serie - 70 dB gain

 

[Trust]

I took not much attention to that lnb since it was not what it should be (X-tal PLL)
Compaired it quickly against my BU at Nilesat 7º W at a few TP's , at most TP's the same quality .
---------------BU---------BEST
-----------sign./qual.--sign./qual.
10.758 V 83/66 80/66
12.467 H 83/70 80/70
12.226 H 78/63 80/67
11.939 V 82/69 80/67
10727 H 77/25 sometimes a lock with the BEST no lock at all .

Keep in mind both lnb's are modified for use with a 120 cm Fibo Gregorian
The BU as Direct2Fibo and the BEST flanged

I was told that the quad is better than a single, just waiting for mine to be put up, my existing LNB is 8 yrs old so I should notice a difference ?!

 

[samoloko]

sat-tv-fan
did you try Best quad lnb

Update

At last warm enough to tweak the dish.

Get fine weather lock on the uk psb ( freesat ) channels on astra 2E and 2F with no pixelation ( even had all the hd ) the maximum lnb still gives the best results when tested on 3 different stb boxes.

Might save up to invest in a larger dustbin lid
