A little less analogue, and a lot more crap.

I see now that there seem to a few dealers selling the Invacom quad C120s again - Some seem to be white and others dark grey but is there any difference in these? I will get one just for futureproofing.
Since Invacom is part of a group that also tooling for mid-sized satellite dishes and complimentary revolving feed systems, it was probably thought better to ramp up manufacture again than let the market go to another.

Thanks for this topic, actually I think Invacom are a piece of crap, I did a lot of tests and they perform worst than a cheap lnb.
Better stay with Inverto black pro single or if you need a quad lnb, any brand on the market will perform a lot better better.

Made some pics from different offset horns .
With non of them the waveguide of that PF scalar makes a smooth connection with the throat of a offset LNBF

Years ago I bought for the fun a PF feedhorn adaptor to attach to a standard LNBF for offset dishes .
Since the new Inverto lnb has a wider outer feedhorn , this adaptor does not fit over a LNBF but it is possible to tape it to this Inverto lnb

Hi Trust, RimaNTSS - one question regarding this topic : would on offset 125 Gibertini this modification for example with gibertini feedhorn c120 and Inverto Black Ultra or Megasat single bring any improvement in better reception result ? This question is only out of curiosity...

It is hard to say. When you do LNB modification to be able of attaching it to the feedhorn, it is very hard to do it perfectly. I think that perfectly adjusted IBU will give you not worse results than the same LNB with attached Gibertiny feedhorn. But knowing the fact that we are all hobbyists here, why not to try to modify IBU by the feedhorn.

Add: And why not ask all forum members, not only me and Wim? :cool:

Tnx RimaNTSS ! to be honest it was adressed on both of you, because i read that you did that stuff in the past and you have the tools to do it, but of course all members of this forum are welcome with their own experience...

Personally, on the gibertini 150, the original gibertini fedhorn and the megasat flange single gave me worse results on the entire engine path. The best results were given by the Ibu twin in combination with the scalar ring. However, the megasat gave me better results on the 28E, as did the ibu and original gibertini fedhorn. Inverto black ultra is not suitable for useful 28e, as well as for positions 19E, 13E. It is significantly worse than other lnbs. At least from my geographical location.
