Did you mean you have used normal LNBFs (not LNBs) on your installations?
Feedhorns could be different, but I thin, here you wish to exclusively speak about Fibo feedhorn.
In that case, your question makes sense. Yes, it is possible to adopt universal LNBF to the Fibo feedhorn. Are you lookinf for single/twin/quad/octo option?

yea just the normal lnbs like this
INVERTO BLACK ULTRA HIGH GAIN TWIN LNB 0.2DB BUYME | eBay

ive already got a single, twin and quad inverto ultra black LNBs, so can i adapt them?

 

[RimaNTSS]

so can i adapt them?

Yes, you can if you have lathe available. If not, ask somebody to help you. You can ask @Trust1 to do that, he has done that many times

can you buy them ready made?

 

[RimaNTSS]

can you buy them ready made?

Yes, you can. But they should be made by somebody
Of course, it is possible to use original Fibo adapter, but then you should use flange LNB.

I too have a IBU LNB I would like to modify, I have seen in the past @RimaNTSS has done this and had some success. Would a conical scalar like this https://www.amazon.com/Conical-Scal...TF8&qid=1518226058&sr=1-9&keywords=c-band+lnb improve any signal on an inverto black lnb?

 

[RimaNTSS]

@mikeisyou In your link there is conical feedhorn for C-band, so, it is totally another story than this topic is about.

This wouldn't work for ku-band?

Not at all. This is only for C-band.

alright thats good to know,
how much do they cost compared to normal LNBs?

 

[mikeisyou]

Here's some interesting DIY homemade foil feedhorns

 

[RimaNTSS]

Have found the picture of some of my Gregorians
Of course, usual universal LNBF cost less than flange LNB. So, it makes sense to use them.

how many fibo gregorians you got mate?

im glad at only getting the one lol

 

[RimaNTSS]

Not all Gregorians are Fibos! But, speaking about double-reflector dishes (not necessary Gregorian), I"ve got ~10 +/- 2 ..... not all installed.

[RimaNTSS]

Are you kidding?! Of course it is 4.6m Gregorian Andrew dish! Did not you see the picture of mine SAT-playground?
Sorry, page 59.

just seen it, it looks sick (as in wicked), im happy for you mate

so are you into feed hunting?
bet you can find all sorts of feeds with that 4.6m dish

btw where abouts are you from? which country?

 

[RimaNTSS]

btw where abouts are you from? which country?

I am from one of the countries where we drive right side of the road, to be more precise - Latvia.
I am not so much interested in feedhunt. SAT-hardware is my deviation.

You don't need a feed horn for Ku band LNB's they have one built into the LNB it's self, adding something like the one in the photo above will do nothing to improve the signal to the LNB, it will however help a bit with signal rejection from another dish (or other high frequency signal source) that may be very close by to your dish.
