@italy2006 Nice picture of your antenna. And how did you measure it 130 cm, from where to where?
does this way increse signal even aliitle?How did you measure it?
It is hard to say as you did not show any pictures of your antenna. But, if you wish to go "the feedhorn and flange LNB" way then you better make sure that the illumination angle of the feedhorn is matching the opening angle of the anten
It is hard to say. This is not standard feedhorn which only exists at your disposal. So, only you can give the answer whether such a feedhorn brings you positive reception results.does this way increse signal even aliitle?
Why don't they use white plastic instead black as this would reflect a good part of the suns heat? They could call them 'White Ultra' which I think they used to do. Another option would be to spray the casing white.@italy2006 a 'sun shade' for your IBU could help. All my Inverto Black Ultras suffer in strong sunshine. Something like a short section of gutter pipe attached with zip-ties will help to stop the LNB cooking in the sun.
I'm thinking that I may have the same problem with the Black Ultra on the Gibby because I'm getting enough signal to lock up most channels on 12594/V/27500 on 53E on the SX88 in the morning and evening ATM, but the levels are dropping off in the middle of the day when it's sunny & hot.@italy2006 a 'sun shade' for your IBU could help.

Sounds like it. I first noticed when I had a fixed 90cm on 10E, I was getting better signal when it was lightly raining than in full sunshine. Then when I tried to tweak the skew for a feed on 24W I noticed I would get lock when my hand was holding the LNB to adjust it, but when I let go within 10 to 20 seconds the signal would disappear.I'm thinking that I may have the same problem with the Black Ultra on the Gibby because I'm getting enough signal to lock up most channels on 12594/V/27500 on 53E on the SX88 in the morning and evening ATM, but the levels are dropping off in the middle of the day when it's sunny & hot.
Might that be similar to the issues that you have without the "sun shields"?
Thx - will be getting some white guttering from Screwfix later today!!Sounds like it.

signal is good for some frequencies but it decereaes during midday and warm weather.solution?@italy2006 a 'sun shade' for your IBU could help. All my Inverto Black Ultras suffer in strong sunshine.

what is best cover fo cooling inverto lnb?Ok !
It seem that the INVERTO IDLB-SINL40-ULTRA-OPP is a good choise if i add a sun cover

I will try it on my fixe CM and anyway if it's not good i will put them on a sat dish for 13° and 19,2°I've never tried one. It looks to have the same body as the Black Ultra Twin, but not the same electronics - according to the image it has a 4G filter which the Black Ultra lacks. I've seen used ones on eBay where the white plastic has turned yellow in the sun.
