Advice Needed Irte dish

[Heeres]

Hallo allemaal, Ik heb hier nog een oude Irte antenneschotel staan die ik wil opknappen, maar wat voor LNBF moet hier op de schotel komen? D is 150 cm in diameter en D is 16,8 cm, wat mij een f/d-verhouding geeft van 0,56. Ik zou het graag willen gebruiken voor ku band en is er iemand anders die hier misschien nog tekeningen van heeft?

Hello everyone, I have an old Irte antenna dish here that I want to refurbish, but what kind of LNBF should be placed on the dish? Dish is 150 cm in diameter and depth is 16.8 cm, which gives me an f/d ratio of 0.56. I would like to use it for ku band and is there anyone else who might have drawings of this?

Only to suggest what has been imaged is not the usual 1.5m IRTE.

One hole in the rim every 90 degrees.

So, a different IRTE dish, with other specifications, see Just Sharing This - IRTE Dish Specifications ?

f/D = 0.56 is different from f/D = 0.41
What feedhorn to use on a f/D 0.56 dish?

I use Shiply for big collection/deliveries. Often very cheap if you are in rush and they fit it in with other jobs. Thanks for the metioning Shiply... I did not know such service existed and arranged a collection of the 1.2m IRTE dish available on eBay yesterday morning.

So the 1.5m IRTE with f/D=0.5x, with extension petals becomes the 2.0m IRTE with f/D=0.4?

"Interesting" way of having a range of dish sizes....

Very strange

I didn't find that this was an IRTE dish, or more specifically the 150cm version.
In the first pages of the topic (that I had indeed found) IRTE isn't mentioned.
So I found it irrelevant for the subject at hand....

You appeared to be interested in ratios when the diameter is increased on a specific parabola.

I'm afraid that is a rather bad summary, of what I was interested in...

I've read post 8 again but can't see anything between the lines.

If it helps Prodelin also increased their prime focus dish range with panel extensions.
