Inverto Twin Black Ultra flange conversion...!!

[DX Excalibur]

Hello!
In the last days I have tested this 2 lnb's. I have modified the inverto black ultra lnb to have the exact dimensions like the Black Pro flange lnb. I have tested them on different sattelites and different transponders.I have buy all lnb's with 2 outputs, because I have see from the white tech lnb's that the single version is weak, and the twin white tech flage have with up to 1db more better signal then the white tech single lnb on the whole band.

I have made the test with my 1.4m Fe prime focus dish, Dm500 HD receiver and only 5-10 minutes between switching lnb's. Signal is in db's and from what I have see, the ultra lnb perform better in the band 11700-12750 with up to 0.5db better signal then black pro for dvbs transponders and more then 0.5db for dvbs2. In the band 10950-11700 signal results are same for both lnb's and for 10700-10950 the black pro has an advantage on horizontal transponders, and for vertical signal is nearly the same with a little advantage for the Black Pro.

11954 H 8.65/8.10
12032 H 8.60/8.15
12051 V 8.85/8.20
12207 V 9.10/7.95
12266 H 8.30/7.65
12344 H 9.00/8.55

I will test it also on my 3.0m prime focus to see the difference between this two lnb's, and write here the results.

Looking forward to seeing the results.

thanx for your report..but just a point , the black pro as you call it its in fact a red tech classic(white) ,,inverto or somebody else just made a black paint work on it ...and the hardware is old ..nothing new on it ..so i would advise to concentrate testing with Black ultra LNB ...regards

 

[samoloko]

are really Inverto flange red tech (white) twin better than single with 1 dB

 

[samoloko]

I am attaching picture from DX Excalibur Inverto twin ultra black
would you please tell me the exact outer diameter d and length L measures
are d constant value along L

regards

 

[DX Excalibur]

@samoloko, d = 21.5 mm
L = 50 mm
d is constant value along L

Looking forward to seeing the results.

I have tested also on the big dish and the results are the same, black ultra performs better then black pro(or white tech) only in the range 11700 - 12750.

I modified Inverto ultra black single to use with prime focus
when attached to waveguide with length 6,5 cm the result Is 2 dB lower than original flange white tech
measurment done with adenin satfinder plug In
at first when the unmodified Inverto ultra black was attached to Triax TD88 I could watch DSF at Astra 1H , after the modification No Signal at this transponder

make sure the inner juction between the C120 adapter and the lnb is completly clean

thank you for reply
the problem Is not In Inner junction
