Mine seems to be working well.
Getting a couple of 25.5E transponders with solid pictures.

CM feedhorn with InvertoC120 twin.

Compared to what Lancelot?

Well, this really.
Pic1 is the old MTI blueline 0.3.
Pic2 is with the CM FH and 0.3 C120.
Pic3 is a screenshot of the Aviation Chnl on 11075V 27500

Oops,30% quality increase,good result!

It's rather well known that the lnbf:s don't work well on the Gibertinis since they are meant for dishes with an f/d of 0.6.
The Channel Master feed also over-illuminates the Gibertini but I guess it lets in a lot less noise than an lnbf.

I use a CD-80 feed from the old days on my Gibertini 100 with a very good result.That feed under-illuminates the dish but I guess the signal is very noise free.

Can you get any thing off the orbit transponders on 25.5 east and can you get any horizontal transpoders on nilesat.

I can get 25.5 east but on my 1.2m but the signal drops out in the rain a 1.8m works fine in the rain as i am more west of the uk

Getting (some) of the H 7W fine with this in the evenings.
Some fine tuning still to be done weather permitting. Haven't tried the orbit chnls yet as this is just a lash up an need a few days to sort it. Promising though

ChannelMaster feedhorn works perfectly well on a Gibertini 1.5m, it has the right f/d ratio, despite what is claimed above. It certainly works better than Gibertini's own feedhorn, a poorly made and cheap piece of kit.
I've tried both feeds in low band weak signals on Gibertini 1.2m and 1.5m, CM beats Gibertini every time.

No LNBF can compete with a C120 LNB with the CM feed on the 1.5m.

I've been trying (unsuccesfully) to tell everyone that for a couple of months now snap.


Cheers.
