Plate which is installed now has 120mm between horizontal holes. Of course, it is possible to make wider plate but then system will become less stable. And, anyway, multifeed-rail should be somehow connected to the plate.

Another try. I think this is more or less final result. Maybe some minor adjustments needed. Someday will do some reception tests. As multifeed is not my priority I made only 13cm between outer LNBs, but distance can be easily extended up to 25-30cm.

Excellent work. Reception tests will be very interesting before we place orders

@Sat1969 you will get discount as it was your proposal how to attach the multifeed rail :)
Even without tests I can say that reception results on the central LNB will be not worse than with original feedarms and LNB-holder, and that is because LNB can be adjusted in all possible dimensions with the aim to co-locate LNB's Phase center with antenna's Focal point. Reception on multifeeded LNBs will also be as they should be in multifeed.

Another work of art - RimaNTSS - ... very nice
It looks good on the pics .... it will look superb in real life ....
the adjustable c band holder rimas c band holder.jpg i got from you early this year certainly did :)

For those who did not see earlier there is collage I made with all needed dimensions (digits are in mm) of several CM dishes. Unfortunately I miss very much Channel Master 0.75m. So, if some of you have it, please, please let me know :)

Well, played enough with multifeed installation, but I do not like multifeeds and abandon this idea. However it is possible to make Channel Master dish multifeed capable.
I will go forward with making new feedarms for all my small CM antennas (0.75-0.9-1.0-1.2m). Of course they will have different sizes feedarms. But all the connection points to the dish and LNB-holders will all be same. When finish with small antennas, will think about 1.8m where another way of connection to the dish should be used, but LNB-holder can also be same. In case of using C-band LNB bigger clamp needs to be installed.
P.S. It is time to mow the grass! :N

Have made bunch of bits which will be attached to the face of the dish and hold the feedarms. They look complicated, and, in fact they are. But I like things to be over-engineered. :eek:

Wow, these look amazing.

Even if they look same, but for 1.2m dishes will be using 10x1.5mm pipe, for smaller antennas 10x1mm. M6 nuts will be welded on each pipe-end. LNB-holder will be same for every antenna.
And how does one place orders? :D

Seriously, though, I have enough project lined up to make a CM120 with new feedarms something that might happen, well, next year?
So, in the meantime, I just sit back and enjoy your projects... :)

I am in process of making more or less universal multifeed LNB-holder for an average offset antenna including 1.8m CM. Chap wants to install 2 C-band LNBs and 1 Ku-band LNB on his motorized 1.8m antenna. C-band LNBs will have ~80mm feedhorns, so this multifeed plank should be OK. Will make feedarms out of 12mm INOX pipe, and they will be adjustable in length.

Have finished the set (feedarms, connectors, multifeed with 3 holders) for a friend of mine. He will be installed all that to nis NSC1.8m and later to CM 1.8m. Dishes are different but length-adjustable feedarms will allow proper adjustments. Yellow wire has 1830mm and 1080mm marks - to place central LNB exactly in antenna's focal point. Feedarm pipes are 14mm in diameter.

Friend of mine has sent me PM he does not need anymore. Of course it is rusty and looks ugly, but all the parts are there. One M8 bolt was broken inside the hole, so it took some time till I got it out. There is no thread anymore, therefore I've drilled 8mm hole through the square bit and long M8 bolt will be used to hold the upper part of the PM. Then I cleaned rust little bit, got bored and put PM in the box till I get the right mood to continue.
