My SAT-playground

Hobbyist will come tomorrow to pickup 1.8m Prodelin. He said he will transfer it on the roof of his Zafira and it is more than 100km travel! Will see how it goes..... in worse case scenario I can loan my trailer to him. To make antenna ready to be installed I made this LNB-holder. Original feedhorn and adopted twin LNB will also go with antenna.

Fixed CM 0.9m on the mount I've got last week. Used 300mm (diameter) plate between the mount and the dish. Then discovered that I run out of proper size bolts which go through face of the dish. Of course I could get them next week from the shop, but just made them longer
It is too late to go outside and install dish, will do that tomorrow.

While drinking my morning coffee, I hanged antenna on the pole. I must say, it is very strong and stable. I think that also 1.2m antenna could easily go on this mount. BTW, beside Azimuth & Elevation control, this mount also has possibility to skew the whole dish ~10*.

I've started too work on the diagram of all connections which I am going to follow this summer. It is not fully complected as there are still some question marks. But my main target is to get 4 lines from 10 quad LNBs to the house, one line from another 10 antennas and reception from one H-H antenna. What is in the dotted red line is stuff in the garage, the rest is outside. All together 3 receivers with 11 tuners plus TV with built-in satellite tuner. There are also 4 terrestrial tuners in the system. So, together 15 satellite dishes and 2 terrestrial ones.
Receivers are green, dishes are yellow, DiseqCs (5 pieces 4/10) are in blue. Altogether 13 Quad LNBs and 7 Single or Twin LNBs. 15 dishes.... maybe little bit more.

Hi! For 1,8m Prodelin antenna I've got new flange LNB made of this http://www.amazon.co.uk/Micro-Twin-LNB-gold-Edition/dp/B004TTNJNI
I hope I measured original feedhorn's flange right and attaching LNB will not be problematic.

Ok this is a long time ago now but here's hoping....

Where did you get the adapter ring, did you make it ?.

 

[RimaNTSS]

Funny, but this LNB with the feedhorn went to another user last week, as he bought my 1.8m Prodelin. Friend of mine made LNB adaptation to feedhorn. Unfortunately that friend passed away couple of years ago but I am sure that @Trust1 can help you in this issue.

Made a new stand for CM dish. Still needs to be painted..... and no Lidl around to get nice paint

 

[RimaNTSS]

Got the package today. Guess what was inside ! Yes, new toys for playground. Thanks @Trust1

Have you now got a full collection of CM Dishes?

Have you now got a full collection of CM Dishes?

Except 2.4m, all European Rx dishes. 6 sizes.

Cassagrain came with no mount, so made one.

Now how is that for statement on this forum??
Eh, lads, if you are lacking a mount at any time, just make one...

 

[Captain Jack]

Nice dish. I like these unusual ones... Whatever happened to Arcon Sweety?

What’s the dome part is that the lnb?

 

[RimaNTSS]

LNB is fitted inside the body in the special plastic case. I do not think that all LNBs can be placed there, but some can.

My .75 CM came with original (I think) Az/El mount. But for well known reasons I will not be installing it . However, it is interesting design. I could use some mount from CM 120, but this antenna has different distance between the holes. So, creating new mount for small brother of CM family. Still thinking how to connect it to vertical pipe

 

[RimaNTSS]

I have always thought that CM standardized everything as much as possible. But , in case of 75cm antenna it is not true. First of all, as I already mentioned, distance between the holes for mount are different from what 0.9m-1m-1.2m antenna have. And secondly, LNB-holder is different and also the way how feedarms connected to it is also different.
But who cares about this if I made special mount, feedarms and LNB-holder for this beautiful dish. Made a test for LNB holder- tightened rope to the end of it and hanged antenna to the ceiling, together about 6kg. Test passed.
The mount will be hold by 30x3mm pipe.
Feedarms are 60/60/40cm in lengths and extendable, so will be no problems to locate LNB in proper position.
LNB-holder will be exactly the same as on other CM antennas in my yard.

Bravo!

Excellent work, @RimaNTSS!
Great to see such DIY enthusiasm with a streak of "because-you-can"...

Holder for antenna itself made from 42.4x2mm pipe. Also tested it by applying ~100kg of weight (did not take picture as hands were busy during the test ).
