Not the structure, but the mere fact of being in the path of the signal means the feedhorn blocks some signal. Thats why an offset dish has more signal gain than a prime focus dish of the same size.

i found it in a naira land forum
Make Your 1.8m Dish To 1.9m - Satellite TV Technology - Nigeria
Looked at those pictures and what they are calling "feedhorns" are LNB holding arms not feedhorns!Not the structure, but the mere fact of being in the path of the signal means the feedhorn blocks some signal. Thats why an offset dish has more signal gain than a prime focus dish of the same size.

Feedhorn is the 'pipe' part of the lnb that guides the waves to the lnb itself (the electronics)
The said holding arms are normally about just 8mm thick. I don't think thieir presence would significantly block signals falling on a 6ft dish. What is happening there in my opinion is, they are adjusting the focal length that was wrongly made by the manufacturer and thus improving the signal.
Some on the thread are also reporting that the modification does not improve the signal at all despite removing the arms. Meaning the original focal length was correct.
They are also saying that by removing the holding arms they are changing the pf dish to offset dish which is just rediculous. I Guess someone doesn't know the fundamental differences between prime focus and offset dishes.
But you wouldn't expect someone who calls dish arms 'feedhorns' to know that.
Nice effort though.
On a 90cm,eh?Even the tps on 12130h and 12168h?I nabbed them once but when a plane flew over my roof they disappeared forever😀.To quote the prezzo,I 'will revisit' this bird.52.5e is another one of those sats I regard as a fat sheep in the FTA pen.In terms of fta,I have simple tastes and I dream of a day when i will get just one sat that nabs my favorite mix-animal docs,football,cartoons and movies.On a 90 cm Nairobi

Yes in English. Most of time we don't talk of channels that are in Arabic like Nat Geo, Cartoon Network, movie & news channels.... But only football channels.
Huh?Then maybe I should stop hating my ES-21 gold lnb so much for not getting anything on 68.5e(even though I am on a 90).The moment you insert a dielectric plate where it's not needed, signal evaporates.
Remove the dielectric plate if you're on 68.5 friend.Huh?Then maybe I should stop hating my ES-21 gold lnb so much for not getting anything on 68.5e(even though I am on a 90).
I don't know why recent strong patches fail to pop the maize that are powerful. You will just watch them rolling keys but no pics.SRT 4955 software v2.71p just in. Crosat.

Says "solves issue with Hotbird". A bird you can only receive with a 20 meter BUD in these parts of the world.Eager to hear whether this one is the game changer or not. Haven't tested it yet.
