Help with 1.8 cm prime focus satellite dish

[wisbech]

I got 1.8 cm prime focus satellite dish and after I set all up I noticed that the (round metal thing in the middle of the dish is missing)
I don’t know what is it called?
Now do I have to buy this thing what is it called and where from can I buy it?
Or it won’t effect the single
Thanks

Without knowing the make of dish, and the type of LNB you are fitting, it is difficult to know whether you can fabricate something to fit.

This is of course if you are talking about the feedhorn, and not the backplate holding the dish onto the mount.


Where did you buy it from, and can the seller/dealer not supply you another ?

This is exactly what I got and its 1.8 cm prime focus (Archsat dish)
And what I meant is this whole in the middle of the dish I can’t remember if the dish spouse to be like that or I lost the metal round ring which it fits on the middle of the dish

hello
if you are refering to the hole in the middle of the dish there is not much to worry.
this is usualy a null spot and not much signal there at all.
some dishes have a cover plate and some have a hole.
if you look at the signal reflected on a prime focus the null spot has nothing there.
this is because the feed horn on the front shadows that spot in the center and its at the bottom of the curve as well

Generally cover is included, but if you are somewhere near equator and elevation of dish is high, manual says to remove that cover, to allow water to drain.

Looks like another incarnation of the Jonsa/Fortecstar.

Wow, 1.8 cm. I've never seen one so small!!!

I guess you mean 1.8 m

I was given one of those a few months back.

(I kept the bolt pack)

Thanks guys for your replies
I bought this dish from eBay for £100 and I thought that was cheap a few months back
The dish make is (ARCHSAT) and it’s not fortecstar
Have anybody heard about this make?

I would guess probably not. The reason Rolf said Fortecstar is because the picture you posted is the same as used for the Fortecstar offering.

Badge engineering still lives!

It's a Jonsa. If you look on the ARCHSAT website, its says so. Identical to the Fortec star ones, which are also Jonsa.
